Silopren™ LSR 2749 is a 40A two component self bonding liquid silicone rubber.
Silopren™ LSR 2749 is a self bonding injection molding silicone rubber material that offers adhesion to polycarbonate (PC), polybutylene terephthalate (PBT) and co-polyesters without the use of a primer and without adhesion to the mold. Adequate bond strength is reached immediately upon demold. This self bonding property of LSR 2749 makes it a cost effective solution for multi component injection molding or insert molding.
Hardness, Shore A: 40
Tensile strength, MPa: 7
