Commonly used products in the field of polyurethane CASE
Application areas: polyurethane coatings, adhesives, elastomers, polyurethane acrylic coatings, fabric coatings, polyurethane pastes, leather finishes, composites, etc.
Characteristics: Delayed, heat-sensitive
Function: Extend the open time, delay the rise of viscosity, does not affect the post-curing
Use system: MDI/TDI/IPDI/HDI/H12MDI/ADI/XDI/mixed isocyanate
Delayed catalyst effect picture Introduction: In CASE field (adhesives, coatings, elastomers), the most commonly used catalyst is DY-12 (dibutyltin dilaurate), which has good selectivity to -NCO and -OH and high activity, but in the preparation of complex products, the operation time given to the workers is short, and it can’t satisfy the construction demand, in this condition, Shanghai Deyin Chemical Co. Ltd. has developed a series of delayed catalysts to recommend more suitable products for different isocyanate systems and construction conditions.
