Product Description

Product Description

Liquid Mold RTV2 Silicone Rubber Food Grade

Food Grade RTV-2 Silicone For Resin Mold  is a two-part-kind liquid silicone, which belongs to food-grade

silicone, can be cured at room temperature, and mainly used for mold making of food-grade molds,

jewelry casting, tire molding, rapid prototyping, vacuum foaming, etc. It also suits any

condensation silicone's application for molding. With appropriate hardness, good tensile and tear

strength, and excellent resistance to deformation, finished silicone molds have not only a durable

life but also good performance.

Operation Methods

Liquid Mold RTV2 Silicone Rubber Food Grade

1. Stir part A (100g) and part B (100g) with 1:1 mixing ratio evenly. Then get the mixture for

vacuum-pumping. (If there is no vacuum machine, you can just pour the mixture slowly from the

corner so that less bubbles caused)

2. Enclose the products (the original model) with four plastic plates or wooden plates.

3. Clean your products and brush a layer of release agent (detergent or soap water) on your

products.

4. Pour the mixed silicone into the model frame.

5. After about 3 to 5 hours, when the silicone is cured, remove the original model, and then you

get a finished addition cured silicone mold.
