    Processing and Instructions of Addition Cured 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.
