Silicone Catalyst

(£3.54 Exc. VAT)

Catalyst for the general purpose RTV Silicone Moulding Rubber available in purple or clear.


When selecting a catalyst please choose the hardness that matches the hardness of rubber it will be used with. The soft and medium catalysts are slightly different and need to be used with their corresponding hardness of rubber. Not doing so will effect the pot life and cure times. It will not change the shore hardness.

3% (3g per 100g) 15-20 minutes 3 hours
