Product detail:

Applications of rtv molding silicone in 30 Shore A

RTV molding silicone in 28-30 Shore A can used for resin crafts ,gypsum crafts ,unsaturated resin crafts, lighting and candles crafts in medium and big size .


Operations of rtv molding silicone in 30 Shore A

& Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent.

 &  Step Two: vacuum pumping

Without exception, this step takes less than 10 minutes.

Note: The time for vacuum-pumping should be less than 3-5 mins , otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.

& Step Three: Brushing cast & Perfusion Molding operation


Features of rtv molding silicone in 30 Shore A

Medium hardness  good for big sized product
Good fluidity good for  product in pouring way .
Can add thickening agent for complex pattern in brushing way
