CeTePox 691 FM Branched polyether-urethane CeTePox PU - Prepolymers >> Polyether ADHESIVE CeTePox 691 FM branched polyether-urethane with capped isocyanate groups like CeTePox 600 FM, reduced viscosity Medium-viscous ether-urethane-polymer with blocked, amine curable isocyanate groups; solvent-free; modified with dioctyl adipate. Usage of CeTePox 691 FM in corresponding formulations gives tough-hard to highly elastic products. Due to the amine crosslink- ing of CeTePox 691 FM, the elastifying properties of polyurethanes can be linked with the known robust characteristics of epoxy resins. CeTePox 691 FM is added to the resin compo- nent; during the cross-linking with suitable amine hardeners, CeTePox 691 FM is built-in in the epoxy resin matrix. Solvent-free, medium-viscous, branched ether-urethane-polymer with blocked, amine curable isocyanate groups and modified with dioctyl adipate. Used for elastifying of amine-curing epoxy systems, such as highly elastic adhesives and sealing materials. Provides tough-hard to highly elastic products.
