Silopren® LSR 2750

Silopren LSR 2750 TP 3824 is a two-component liquid silicone rubber for injection moulding, which offers primer-less adhesion to a wide range of substrates including metals and engineering plastics, but without adhesion to the mould. Full bond strength is reached after a short post cure (e.g. 1 h at 100°C) or by longer storage at room temperature. This makes Silopren LSR 2750 TP 3824 the optimal choice for cost-efficient manufacturing of high numbers of articles in integrated processes such as multi-component injection moulding or insert-moulding.

Key Features and Benefits

• Primer-less adhesion to many substrates

• No special mould treatment needed: Final adhesion builds up with time

• High temperature stability

• Excellent stability and flexibility at low temperatures

• Outstanding ageing behavior and weathering resistance

• Good dielectric and mechanical properties

• Easy pigmentable due to translucent colour

Potential Applications
Silopren LSR 2750 TP 3824 is particularly suitable for the manufacturing of parts, where engineering plastics and elastomeric materials need to be combined in an overmoulding or co-moulding process such as sealing elements, automotive connectors, membranes, vibration dampening elements, etc. Parts made from Silopren LSR 2750 TP 3824 can generally be used in technical applications without post-cure, but do not comply with regulations applicable for parts, which are intended for the pharmaceutical or food industry.
