KUPA 429
General description and applications
KUPA 429 is polyurethane rigid foam system for spray
KUPA 429 reacts with MDI offering fast curring good adhesion to the walls and glving foam with good insulating properties
Due to its good flow the foam in cabinet is homogencously distributed and show ,in addition ,a good structure and absence of holes .
