It supports deep vulcanization without being limited by product thickness, adapting to the production of thick and large automotive components. The product is non-toxic and odorless, meeting environmental protection requirements for industrial production. It possesses good fluidity for easy operation, reducing processing difficulty and labor costs. It offers excellent chemical corrosion resistance and wide temperature resistance from -50℃ to 250℃, maintaining stable performance in harsh environments. With high tensile and tear strength, it achieves more molding times and prolongs the service life of molds effectively.
Usage Instructions
Step 1: Mix the two liquid components A and B of the silicone in the specified ratio, and stir evenly to avoid introducing excess air bubbles.
Step 2: Conduct vacuum degassing treatment on the mixed silicone, with the degassing time controlled within a reasonable range to ensure complete bubble removal without affecting curing.
Step 3: Choose pouring or coating operation according to the structure of the auto parts master model, and apply the silicone evenly on the master model surface.
Step 4: Wait for the silicone to complete deep vulcanization at room temperature, and do not disturb the curing process.
Step 5: After full curing, carefully demold to obtain the auto parts mold, which can be put into formal production after standing for a period of time.
