UV Process Supply, Inc. founded in 1979 with the goal to service the growing UV Curing market. At that time there were only companies producing UV coatings and/or Inks, and UV Curing equipment. The realization was that it took more than these two components to do a “process”. What else is needed to create a successful application?
With that five product categories were created to address the problems associated with the physical properties of the process.
Safety Products was the first category, and hand cleaner was the first product. Most waterless hand cleaners are made with mineral sprits, and that solvent used with acrylates can lead to skin problems. We created a waterless hand cleaner that was oil based rather than solvent based.
Next was our skin lotion, which contains aluminum hydroxide able to neutralize the acrylic acid based coatings. Gloves were all tested with the most popular monomers to insure that they would provide proper protection when used with clean up solvents. Thus we do not carry vinyl gloves as they do no not provide proper protection with UV Coatings and inks.
Barrier creams were a natural requirement as they present additional protection especially around finger nails and under rings, where inks might collect unnoticed. In the area of eye protection, all products are rated based on the ability to filter UV light. Even our splash goggles filter UV as to always insure optimum protection.
Ink and Coating Handling is our second category and represents two features associated with the process. First is safety related; that if you can pump the coating, there is less physical contact with the material that can cause a problem. We learned to specify the proper pumps for UV Curing from customer experience. They learned that if they were using a piston pump, it would seize, when the friction of the piston would cause minute polymerization on the interior wall of the pump.
So the pumps need to be either double diaphragm pumps or peristaltic. All wetted parts in the pump product line has been soak tested in the popular monomers to insure that there would be no swelling or adverse effect on the pumps life. Storage containers need to be able to provide oxygen as it prevents jelling and curing in the container, black polyethylene containers are the best way to store UV inks and coatings. Metal should not be used. To offer a full line of UV appropriate products we have selected from each of our suppliers the best for UV Curing products.
Keep in mind that we have access to hundreds of other products from these vendors which may not be considered “Best for UV”, and we can provide them at competitive pricing.
