Product Features & Advantages
This RTV-2 silicone has an oil-free formula, keeping molds and finished products clean without surface contamination, and prolonging service life effectively. It features extended shelf life, reducing material waste caused by storage and lowering inventory costs for buyers. With stronger tensile and tear strength, it has excellent acid and alkali resistance, adapting to harsh industrial use environments. Ultra-low shrinkage ensures stable size of molds and finished products, avoiding deformation and guaranteeing production precision. It is easy to clean repeatedly, maintaining good surface performance for long-term use, and has better high temperature resistance to expand application scenarios.
How to Use the Product
Step 1: Select the suitable curing system and silicone grade based on usage scenarios, such as food grade for food molds, industrial grade for conventional mold making.
Step 2: Clean the original mold or operation carrier thoroughly, remove dust, grease and other impurities to ensure normal curing.
Step 3: Use an electronic scale to weigh part A and part B accurately according to the specified mixing ratio.
Step 4: Stir the two components fully and evenly until they are completely fused, avoiding partial curing or performance attenuation.
Step 5: Conduct pouring, brushing, potting or filling according to actual needs, and wait for full room temperature curing before subsequent operation.
Application Scenarios
This product is widely used in multiple fields. For mold making, it applies to GRC, plaster, stone, cement, resin products, shoe molds and tire molds; it can produce food-grade molds for cake, chocolate and candies.
