Platinum Cured Silicone Rubber Food Grade For Resin And Cake Mold Making With LGFB
Liquid silicone rubbers are pumpable two-part compounds that are delivered ready to use. They are vulcanized by addition curing.
Component A contains catalyst and component B functional polysiloxane as a curing agent.
Compared to peroxide curing, liquid silicone rubbers do not release any curing by-products.

Typical properties of the vulcanisate:
The mixing ratio of components A: B = 1: 1.
Vulcanization: 5 min. 150 °C + 4 hrs. 200 °C post cure
LSR is platinum cured(vulcanized) materials which are mixed in a 1:1 ratio by weight.
