Why choose Mclogan Chemicals?

Mclogan Chemicals are bought in large quantities from the top manufacturers to ensure that our customers are getting the lowest possible prices, but still the highest quality products that they are used to.  In this blog we will highlight each chemical, how to use it and how these chemicals are the exact same as some of the brands you may be using.

  • Mclogan Screen Opener is the same product as the Sprayway 957 Instant Screen Opener; use this spray to unclog your screens.  This can happen when you screen print where your ink may begin to dry and get clogged in the mesh.  Some screen printers also use this product to clean their squeegees.
  • Mclogan Flash Adhesive (Super Flash Adhesive 384) when doing multiple color printing jobs flash adhesive is the best chemical to use when you flash your different colors.  Regular adhesive will start to break down during an 8-10 second flash, which can move your shirt and then the colors/image will not line up correctly.
  • Mclogan Spray Adhesive this is mainly for single color screen printing, or if you needed to secure your paper stock.
  • Mclogan Degreaser product made by CCI.  This is your FIRST step in screen printing to ensure that your screen is free of all grease before you put on your emulsion.  Emulsion will not stick to any type of oil or grease.  This degreaser is a concentrated liquid that will make 2 gallons per 1 gallon of degreaser.
  • Mclogan Emulsion Remover Concentrate product by CCI.  This is another concentrated liquid that will make 4 gallons per 1 gallon emulsion remover.  After you are done screen printing use this emulsion remover concentrate to remove your emulsion.  This will ensure that your screen is ready for it’s next job and application of the Mclogan Degreaser.
  • Mclogan Textile Press Wash this product is made by CCI as an eco friendly citrus smelling screen wash.  Prevent build up of plastisol inks on your screens with this wash, to ensure that you don’t stain your screen or get ghostlike images from your image print.
  • Mclogan Screen Wash (Fast Open 032 Water Based Screen Opener) Aerosol can used for a fast and easy clean up after screen printing with water based inks such as Mazdar 9500 Series, Matsui 301 Series and Permaset Inks.  You can not clean a screen with water that you’ve used for water based screen printing…it just doesn’t work.

Add these cost effective chemicals into your shops and let us know if you have any questions.

How Weather Effects Screen Printing Ink

Mixing screen printing inkScreen printers who have their own shops have probably learned the hard way when dealing with screen printing ink and the climate in which they live. Properly storing your inks for winter and summer, based upon your location is crucial to prolonging the life of your inks.

In winter, water-based inks and emulsions can freeze since they have a high water content.  It’s best to keep these inks above ground, and in insulated rooms.  The screen printing ink shouldn’t get too cold since that will change up the viscosity, which will then make it much harder to print.

We  suggest ordering a 3 month supply of all of your screen printing ink before winter.  If that isn’t an option for you then the best time to order a product, when you have to worry about weather, is on a Monday since the product will constantly be transit.

In the summer, store all screen printing ink in a cool area away from direct sunlight. Any excessive heat, about 180 to 240 degrees, can start the gelling process and make your silk screening inks thick and hard to print. Always get in the habit of mixing the inks before printing to help break down any false body that has occurred due to heat.

When dealing with heat there is usually humidity too.  100% cotton textiles will hold more moisture; more so then 50/50 blends of nylon.  It’s advised to dry 100% cotton textiles at a higher temperature.  You will want your screen printing garment to reach 212 degrees Fahrenheit before the curing process can start.  When drying your garments they will release moisture, so it is best to load up your dryer with test prints to test what cure temperature you should be using depending on the conditions of the day that you are printing.

Some people have problems with under curing in the summer due to them blasting the air conditioning, or due to the placement of their conveyor dryer.  You want your conveyer dryer to not be in direct contact with drafts from windows, vents, fans, etc.  These factors can cool down your dryer leaving you with a cooler dryer temperature then needed to ensure a solid cure.

How To Avoid Unwanted Marks While Screen Printing

Screen printingThere are many important steps that screen printers must go through while screen printing to ensure a perfect product.  Unfortunately, all screen printers occasionally get unwanted marks or ghost images on their textiles.

Here’s some mandatory steps that you might be forgetting that will mess up any job.

  • Screens must be replaced.  When Franmar D-Haze Remover  Gel is used it is so strong that it will actually weaken the mesh.  When your mesh is distorted, or in some way damaged then it is time to replace your screen and this will depend on how much you are printing.  Aluminum screens are also recommended over wooden screens since the aluminum screens will not warp.
  • Periodically replace your squeegees.  Your squeegee is one of the most important tools to successfully screen print.  Any deformities in the squeegee blade can relate back to an unwanted mark or uneven print.  Anyways have extra squeegees on hand in your shop in case something happens to the one you are using while printing.
  • Mesh tightness and consistency with screen printing.  When you push or pull your squeegee you want the mesh to slightly come into contact with your garment.  As you move the squeegee the tight mesh should spring back to it’s original tightness.  When setting up your screen you want the screen to be about an 1/8th of an inch away from the textile, and this is what screen printers call off contact printing.  If your mesh is too loose then you will have problems with the ink pooling and creating a ring/halo around your design.
  • Clean your  silk-screen.  At the end of your  silk-screening job your what to take your Mclogan Emulsion Remover Concentrate to remove the image.  Then take your Franmar D-Haze Remover to remove the ghost image.  Make sure before you begin your next screen printing job that you use the Mclogan Degreaser, or the Ulano #3 Screen Degreaser to ensure that your screen is ready for your emulsion.  Having a screen that is not properly cleaned or prepared will make it harder for your emulsion set the mesh.

If you’ve experienced any of the problems shown below while screen printing then hopefully this will help with your next job.  Make sure to stop by our website to purchase your Mclogan Emulsion Remover Concentrate and McLogan Degreaser.

Ulano Emulsions – MFG Spotlight

  Ulano EmulsionsThe process of silkscreen/screen printing uses a light sensitive coating to record an image. This chemical coating is called the emulsion.  The screen is completely coated with emulsion and then exposed to the light under a positive of the desired image (similar to photography).  Afterward, the emulsion washes away from the unexposed areas with water, so the ink will go through and the design becomes a print.  Within the silkscreen/screen printing process there are also different kinds of emulsion to use, depending on the kind of ink and equipment you are using.

1. Ulano 925 WR:  Ulano EmulsionsA lot of beginner start screen printing with water-based inks for their textiles so Ulano 925 WR is a perfect emulsion to start with.    Ulano 925 WR comes with a syrup diazo sensitizer for easy, fast mixing.  Beginners usually use the sun to expose their screens; Ulano 925 is the best for this since it has a longer time allowed in the sun (time depends on the UV index) during the exposing process.

~Diazo:  This type of emulsion is thick and durable. It is easy to see when the emulsion on the screen is exposed because the color changes.  A quart will cover between 20 to 25 screens, if they are the standard 18- by 24-inch size.  It can be messy however, and needs to be mixed with a sensitizer or activator before it becomes light sensitive.  This emulsion will keep for six to eight months before being mixed with activator, but after you mix it the shelf life is only three months maximum.

2.Ulano Emulsions  Ulano QTX is an emulsion that is ready-to-use since it does not require mixing like the Ulano 925 WR.  It is ultra-fast exposing SBQ photopolymer direct emulsion formulated for textile printing.  This high solid content allows for superior coating properties, better bridging of coarse mesh, and it dries fast.  QTX is used for plastisol inks, and short run water-base printing.  QTX will break down over time if you continually use water-based inks.  Do not use strong solvents during the printing or wash-up period.  QTX is presensitized, and must be handled in safe light conditions before exposure…no UV light.

~Photopolymer:  This is a professional quality emulsion that has much quicker and more stable exposure times.   Photopolymer can take the image in seconds and dries fast after being coated.  You can apply several coats quickly, creating a thick layer of emulsion that will work well if you are printing on a rougher textile, like sports clothes or denim. Pure photopolymer is often sold “pre-sensitized” so it does not need to be mixed.

3.Ulano Emulsions  Ulano QT-DISCHARGE is specially formulated to resist discharge inks and is compatible with water-based and plastisol inks too. You may wonder why people bother with buying the other two emulsions when this one can do it all, and the answer is that people find emulsions that work best for them…it’s just a preference.  Ulano QT-DISCHARGE  requires fewer coats than Ulano 925 WR, dries more quickly and exposes twice as fast.  QT-DISCHARGE has a high (41%) solids content, providing good stencil build per coat, excellent mesh bridging of coarse mesh, and fast drying. It utilizes a powder diazo (rather than 925WR’s syrup).

~Dual Cure:  This emulsion combines qualities of diazo and photopolymer together.  It has a fast exposure time and changes color when it’s finished exposing. Dual cure also gives the screen a heavy coating and holds the image well.  Dual Cure does need to be mixed with an activator chemical and has the same shelf life as the diazo. Inexperienced printers can also use it successfully, but the fast exposure time makes it a little more challenging for beginners.

If you have problems with the emulsions you use, here are a few pointers to help you:

  • Using lower-wattage light bulbs to expose screens can result in images that aren’t crisp or in the emulsion washing out where it’s not supposed to. Instead of spending a lot of time touching up the screen with screen filler, try using dual cure emulsion.
  • Although the Diazo is the most forgiving of the various types of emulsions, it is also the slowest to expose. Dual cure hardens (cures) faster and can especially make a difference for those using a weak source of light for exposure.
  • Use a reliable, industry-supplied light source…like a Ranar CBX Exposure Unit or a Ranar 24×26 Exposure Unit.
  • Certain emulsions must be mixed with a distilled/bottled water.  Using tap water which has certain bacterias can ruin your emulsion.
  • For emulsions that you mix allow them to sit for 15 mins before using.
  • Use a scoop-coater to apply the emulsion evenly on your mesh.
