Cilbond® 48 is a clear, single-component bonding agent designed for both cold and hot-cure applications (65-275°F/20-135°C) with castable polyurethane systems and injection-molded thermoplastic polyurethane (TPU) systems on metal and plastic substrates. It provides exceptional corrosion resistance and offers the advantage of fast drying. Cilbond® 48 can be used without the need for a pre-bake process and has been specifically developed for use in dynamic conditions where hydrolytic stability is crucial.

Chemical Family: Polyurethanes (PU)

Application Method: Brush, Dip Coating, Roll Coater, Spray

Compatible Substrates & Surfaces: Epoxies, Fabrics, Fibre-reinforced Plastic (FRP), Glass Fibre Reinforced Polymer (GFRP), Metal, Plastics, Poly(p-Phenylene Oxide) (PPO), Polyamide, Polybutylene Terephthalate (PBT), Polyesters, Polyether Ether Ketone (PEEK), Polyethersulfone (PES), Polyethylene Terephthalate (PET), Polyphenylene Sulfide (PPS), Polyurethane, Thermoplastic Polyurethane Elastomer (TPU)
