Silopren™ LSR 2742
Silopren* LSR 2742 is a two-component, self-bonding injection molded liquid silicone rubber that offers primer-less adhesion to a wide range of substrates (e.g. engineering plastics, metals) that predominately includes polyesters such as PBT, without sticking to the mold during manufacturing.
Key Features & Typical Benefits
- Primer-less adhesion to many substrates without the need for special mold treatment
- High thermal stability
- Excellent stability and flexibility at low temperatures
- Long service life at dynamic stress
- Good rubber-like properties
- High stability under exposure to ozone and ultraviolet light
- Outstanding resistance to aging
- Excellent dielectric behavior over a wide range of temperatures
- Low combustibility; does not melt or drip
- Ease of pigmentation with LSR Color Pastes
Potential Applications
Due primarily to its self-bonding properties, LSR 2742 is an excellent choice for the production of multi component articles in a cost efficient integrated process (multi component injection molding, over molding). Because of its outstanding properties, LSR 2742 offers particular benefit to the manufacture of soft/rigid combinations out of engineering plastics and LSR e.g. sealing elements, membranes, shower heads or wherever a gasket is needed on a thermoplastic substrate.
