LIM®9071 ET TP 3915 liquid silicone rubber is a 2-component liquid injection moulding material which offers primerless adhesion to a wide range of substrates including metals and many engineering plastics, making it an ideal material for insert moulding applications. LIM®9071 ET TP 3915 liquid silicone rubber is designed to be used in a 1:1 mix ratio and cures rapidly at moulding temperatures of 150°C - 190°C to a high tear strength, translucent silicone elastomer.

Key Features and Benefits
  • Primerless adhesion to many substrates
  • Maximum adhesion immediately after de-moulding
  • High temperature stability
  • Excellent stability and flexibility at low temperatures
  • Outstanding ageing behaviour and weathering resistance
  • Good mechanical properties
  • Easy pigmentable due to translucent colour

Potential Applications
LIM®9071 ET TP 3915 is particularly suitable for the manufacturing of parts, where engineering plastics and elastomeric materials need to be combined in an over moulding or co-moulding process such as sealing elements, automotive connectors, membranes vibration dampening elements, etc.
