Aldehyde scavenger improves automotive interior air quality
A new-generation aldehyde scavenger reduces formaldehyde and acetaldehyde in automotive molded foam, helping eliminate new-car odor and meet increasingly strict cabin-air standards without altering foam processing.
Raising crosslink density in waterborne PU coatings after water evaporation
A key challenge for waterborne coatings is the crosslink density of the film once the water has evaporated. The right catalyst accelerates molecular crosslinking during and…
Waterborne polyurethane catalysts: improving WPU resin cure
Traditional waterborne polyurethane can suffer from slow cure and poor water resistance. Targeted catalysts address these limitations, raising crosslink density and broadening the application window for…
High-activity PU curing catalysts solve slow cure in humid weather
In high-humidity conditions the cure speed of polyurethane coatings is severely affected, lengthening construction cycles and risking lower film quality. High-activity catalysts restore fast, reliable cure…
