(p-toluenesulfonyl isocyanate) PTSI is a chemical, also known as TI or additive-TI. It is used to reduce moisture problems in polyurethane-based (1K & 2K) coating systems, sealants, adhesives, polyurethane elastomers and inks. PTSI helps you to ensuring the quality and shelf-life of urethane-based products.
Moisture scavengers allow formulator to produce high quality polyurethanes.
Properties
Due to the rapid reaction with water, there will be no water vapor when heated, so that for example no bubbles will form. Undesirable reactions of the end product with water (e.g. in isocyanates) are therefor also prevented.
Due to the reaction with water (or hydrogen atoms) problems with water or moisture are avoided or greatly reduced. The reaction produces toluenesulphonamide, a crystalline product which has no disturbing effect in the end products. CO2 may also be formed
