PU CASE Additives | VALIREX & VALIKAT Bi, Zn
Isocyanate Blocking Agents & Bismuth, Zinc Catalysts
for Polyurethane Coatings, Adhesives, Sealants and Elastomers
There are two segments in our PU CASE product range. One segment includes chemicals that allow to block isocyanates in PU systems. The other segment contains metal-based polyurethane catalysts with varying levels of bismuth and/or zinc, which allows for different end-properties of the PU formulation. By adjusting the bismuth and/or zinc concentrations, the reaction profile between the polyol and isocyanate can be fine-tuned. This leads to an ideal processing time and manufacturing efficiency.
To achieve the desired end-properties of your formulation, such as hardness, flexibility, and durability, it is crucial to make a well-considered selection of PU catalysts and additives. This will create an ideal rise and cure profile.
Isocyanate Blocking Agents - VALIREX NOVAL NEXT
If you're looking for a solution to enhance the stability of your polyurethane coatings and adhesives, our VALIREX NOVAL NEXT products are the perfect choice. These chemical compounds work as a blocking agent for isocyanates by creating stable, inactive derivatives. When the blocking agent is removed, the derivative re-activates, allowing isocyanates to react with polyols during the curing process. Blocked isocyanates offer several benefits, including extended storage stability.
