Detailed

RTV silicone rubber for architectural glass reinforced gypsum mouldings

Description

Architectural glass reinforced gypsum silicone is kind of mold making silicone rubber. It’s generally named two-components silicone rubber which will be cured under room temperature, Part A is a flowable liquid, part B is the curing agent. It features an exceptional fluidity and good operability.

Two kinds of silicone rubber can be used for construction, one is condensation cure silicone rubber with mixing ratio 100:3, another is addition cure silicone rubber with mixing ratio 1:1.

Using instructions

Step 1: prepare the original molds

Step 2: Take 100 parts A and add 3 parts B and mix the silicone rubber and curing agent evenly.

Step 3: Pouring cast or brushing cast

*Notes: We usaully use soft silicone rubber to make molds by pouring molding, which is easy for demoulding and will not damage the product in the silicone molds.)
