Product Features & Advantages
This RTV-2 silicone adopts an oil-free formula, keeping molds and finished products clean without residue contamination, effectively extending service life. It has a longer shelf life, reducing material waste and lowering buyers’ inventory management costs. With enhanced tensile and tear strength, it performs well in acid and alkali resistance, adapting to harsh industrial working environments. Ultra-low shrinkage ensures stable dimensions of molds and finished parts, avoiding deformation and guaranteeing production accuracy. It allows repeated cleaning while maintaining good surface condition, and has better high temperature resistance to expand applicable scenarios.
How to Use the Product
Step 1: Choose the matching curing system and silicone grade based on application scenarios, such as food grade for edible molds, industrial grade for conventional mold making.
Step 2: Clean the original mold or operation surface thoroughly, remove dust, grease and impurities to ensure normal, complete 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 fully blended, preventing partial curing or performance loss.
Step 5: Conduct pouring, brushing, potting or filling as needed, and wait for full room temperature curing before demolding or further processing.
Application Scenarios
This product covers a wide range of industrial and craft applications. For mold making, it fits GRC, plaster, cement, resin crafts, shoe molds and bag hardware molds; it can produce food-grade molds for cake, chocolate and candies. It is used for vacuum bag manufacturing, life casting of human body parts and film & television props. As electronic potting compound, it protects PCB, LED lights, solar panels and digital devices. It is used to make pad printing silicone for toys, textile coatings and trademarks, serve as foamed silicone filling material, and produce buffer cushions like shoe insoles and breast prostheses, helping buyers improve efficiency and cut production costs.
