*Goodtensile and tear strength
*Outstanding bubble releasing
*Non-deformation
*Low shrinkage
*Aging resistance,high temperature resistance (200ºC)
*Environmentally, food-gradeOperationinstructions
Step 1: prepare the original molds
Prepare an perfect original mold and clean it totally before operation .
*Notes:Make sure your original moldsand operation tool cleaned up totally to avoid uncure problem .Step 2: Take 100GpartA and100 Gpart B(Or 100 Gpart Aand 10 Gpart B)and mix themevenly.
*Notes:Addition cure moldmaktallurgy-Machinery-p3748/">metallurgy Machinery ingsilicon rubber istwo partflowing liquid, Pls follow the step strictly:
1.Weigh the two part exactly by electronic weight..
If any part not in exactly weight ,it may cause changing of hardness ,or even cause uncure problem.
2.Mix part Aand part Bevenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What's more,
the finished molds will meet ashort life. All of these will cause awaste of silicon rubber.
Step 3: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will causecross linking reaction, and no more further steps will be available.Step 4: Pouring castingorBrushoperation
*Notes:1.For simple pattern products we suggest use pouring operation way ,which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air .
2.For delicate pattern products we suggest use brushing operation way ,which can copy the pattern exactly .Brushable silicone require high viscosity which won't be easy to flow away and easy to brush .
3.We suggest to set the silicone mold for another 12 hours afGas Generation Equipment & Parts ter demould before put into large production .Warm tips :As addition cure silicone is akind of platinum cure system ,which will be easy to cause uncure problem ,soKindly follow the tips below :
*Do notmixwithliquidcondensation silicone rubberor even the tool which used for condensation silicone
*Do not mix withorganic matter whichcontainsN, S, Porganics and ionic compound like Sn, As,Hg, Ph,
*Do not add any pigment or powder into the addition cure silicone rubberwithout any testing toprevent uncureproblemPackage
