Additives for PU sealant

The additives for PU sealant portfolio is developed for sealant manufacturers needing control over curing speed, adhesion, and long-term flexibility. These additives enhance cohesion, reduce shrinkage, and improve UV and chemical resistance. Perfect for OEM building, automotive, and electronics applications, they ensure smooth application and stable curing. They also prevent bubble formation and cracking under temperature cycling. With custom additive packages available for one- or two-component sealants, we help global producers achieve superior sealing and bonding performance in demanding environments.
