Casting plaster gypsum mold tin silicones rubber with catalyst
tin Silicone rubber can used for gypsum crafts, gypsum statues , gypsum ceiling rose , gypsum columns gypsum line , gypsum ceiling board ,and all kinds of gypsum decorations .
Features of casting plaster gypsum mold tin silicones rubber with catalyst :
Tin Silicone rubber is two part silicone with general hardness of 22-50A°after curing features ------
(1) high tensile & tear strength
(2) high duplication times
(3) Low linear shrinkage
(4) resistance to high-temperature
(5) Low shrinkage and non-deformation
(6) resistance to acid-alkali and expansion
Instructions of tin Silicone RTV :
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Step Two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3 to 5minutes, otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step Three: Pouring the mixture into the frame with original gypsum mold slowly .
Shelf life for Liquid Silicone rubber
10~12months, when stored in a dry & cool place under the room temperature 25.
Packing for Liquid Silicone rubber
1kg/ bottle , 5 kg/drum vacuumed packing, 25kgs/drum vacuumed packing,200 kg/drum
Frequently asked questions of RTV molding silicon rubber for resin, plaster products copied
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
