concrete molds making Hongye Silicone rubber
Applications
1. Silicone rubber is mainly used for concrete statue ,concrete veneer, concrete paving, concrete fountain , faux stone, man -made stone and all kinds of concrete products .
Features
Silicon rubber for concrete molds is white flowing liquid with general hardness of 22-50A°after curing with 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
Step One: Take part A and add 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 3-5 minutes ,otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step Three: Pouring the vacuumed silicone mixture into the frame with original concrete mold .
Shelf life for silicon rubber concrete molds
12months, when stored in a dry & cool place under the room temperature 25.
Packing for silicon rubber for concrete molds
25kgs/drum vacuumed packing, 200 kg/drum
