Silopren LSR 2752 is a two-component, selfbonding liquid silicone rubber for injection moulding processes showing primerless adhesion to a wide range of substrates (e.g. engineering plastics, metals) without adhesion to the mould during manufacturing.

Key Features and Benefits

primerless adhesion to many substrates without necessity of any special mould treatment

high thermal stability

excellent stability and flexibility at low temperatures

long service life at dynamic stress

good rubber-like properties

high stability to ozone and ultraviolet light

outstanding resistance to ageing

excellent dielectric behavior over a wide range of temperatures

not readily combustible, does not melt or drip

easy-pigmentable with LSR Colour Pastes

Potential Applications
Due to the selfbonding properties SiloprenLSR 2752 is the optimal choice for the production of multi component articles in a cost efficient integrated process (multi component injection moulding, overmoulding). Because of the outstanding properties SiloprenLSR 2752 is particularly suitable for the manufacturing of soft/rigid combinations out of engineering plastics and Silopren LSR e.g. sealing elements, membranes, shower heads or wherever a gasket is needed on a thermoplastic substrate.
