Silopren™ LSR 2740

Silopren™ LSR 2740 TP 3783 is a two-component liquid silicone rubber for injection molding, which offers primer-less adhesion to a wide range of substrates including metals and engineering plastics, but without adhesion to the mold. Full bond strength is generally reached after a short post cure (e.g. one hour at 100 degrees Celsius) or by longer storage at room temperature. This makes Silopren™ LSR 2740 liquid silicone rubber a good option to consider for cost-efficient manufacturing of high part-quantities in integrated processes, such as multi-component injection molding or insert-molding.Key Features and Benefits Primer-less adhesion to many substrates No special mold treatment needed (final adhesion builds up with time) High temperature stability Excellent stability and flexibility at low temperatures Favorable aging behavior and weathering resistance Good dielectric and mechanical properties Easy to pigment with LSR color-pastes.
