TL321 is our best aliphatic urethane for top coating epoxy. It is considered a high performance product and has the best overall ratings, abrasion resistance and chemical resistance. Unfortunately there are many areas we cannot ship it.
TL322 is the next step. It meets many VOC laws and still outperforms many other products.
All of our aliphatic urethane provide increase chemical resistance and UV resistance over epoxy top coats and other types of urethane. Also, we are able to tint many of our urethane. This increases the products ability to hide stains and increases UV resistance but it not generally recommended for broadcast systems (paint flake or quartz)
