TECHTHANE® 90SS-MB TECHTHANE 90SS-MB is a high performance, high build urethane elastomer spray lining offering the highest level of fine particle abrasion resistance in a batch-mix spray. It also possesses other properties such as high tensile strength, good elongation, and adhesion. As an aliphatic-hybrid urethane-urea, 90SS-MB has significantly better hydrolytic stability, UV stability, and resistance to many chemicals than aromatic urethanes, and is not affected by moisture as are standard urethanes. It applies quickly with coats of up to 20 mils (0.50mm) DFT on horizontal or vertical surfaces which also cure quickly. Typical applications involve abrasion resistance, or where a very hydrolytically stable urethane is required. |
