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
