Processing and Instructions of Addition Cure Silicones
Processing and Instructions of Addition Cure Liquid Silicones Rubber
Step 1
The ideal working temperature is around a constant 25°C. Best
results can be obtained at constant temperatures between 21°C and
26°C, in a clean, dry, dust-free environment. Avoid working in high
humidity.
Step 2
Measure product in accordance with your intended use. Prepare 1
part A to 1 part B by weight and pour into a clean, smooth-sided
container large enough to hold all the liquid and allow room for
mixing.
Step 3
The material must be mixed thoroughly for at least 5 minutes. make
sure to scrape the container sides, bottom, and corners as you mix.
Be careful not to whip excessive air into the mixture.
Step 4
Prepare a container(not silicone material),add the item and keep
them face up.
Pour the mixed silicone onto the container and distribute evenly to
cover the top of the item by at least 6-7mm
Step 5
Adjust the position and then let it cure, the bubbles will melt
gradually.
Step 6
Pull the item out of the mold
Note:
Contamination from sulfur (e.g., sulfur-based clay), amines, tin
compounds, cured polyester resin, some paints and some silicone
rubbers may inhibit surface cure of platinum-cured rubbers.
Apply a release agent, Although not usually necessary, a release agent will make demolding easier when casting into most surfaces.
