How to Use the Product
Step 1: Select the corresponding RTV2 silicone grade according to actual application scenarios, and confirm the matching curing system and mixing ratio.
Step 2: Accurately weigh component A and component B as per the specified ratio, stir the mixture slowly and evenly to avoid excessive air bubbles generated by rapid stirring.
Step 3: Put the fully mixed silicone into a vacuum machine for 2 to 3 minutes of defoaming treatment to remove internal bubbles and ensure smooth finished products.
Step 4: Pour or brush the defoamed silicone into the mold, electronic component or target area according to usage requirements.
Step 5: Let the silicone cure completely at room temperature, and demold or put into use after full curing, following the special guidelines of different grades for optimal results.
Application Scenarios
Our RTV2 Liquid Silicone Rubber covers six core application fields. It is widely used for mold making, including food molds for chocolate, cake, candy and baking, as well as resin jewelry, diamond and rapid prototyping molds.
