Manufactory price RTV-2 liquid silicone rubber for mold making with super quality food grade platinum cure silicone

short description:

Addition liquid silicone rubber

Addition liquid silicone rubber is a non-toxic and odorless silicone material with excellent moisture resistance, cold resistance, heat resistance, insulation, radiation resistance and weather resistance.

It can be bonded with a variety of materials, such as PC, PA, TPU and ABS. The use of addition-type liquid silicone rubber anchoring agent can improve the bonding production efficiency of silicone rubber and these materials and make them integrated. Chemically molded products are safer, non-toxic and solvent-free.

Addition liquid silicone rubber is mainly used in electronic and electrical, construction, automobile, machinery, medical and other fields.

What is the curing agent for addition silicone rubber?

The curing agent of addition silicone rubber is platinum catalyst

Addition silicone rubber is mostly cured through platinum catalysts, such as food-grade silicone, injection molding silicone, etc.

Two-component addition silicone rubber is mainly composed of vinyl polydimethylsiloxane and hydrogen polydimethylsiloxane. Under the catalysis of platinum catalyst, a hydrosilylation reaction occurs, and the cross-linked network is formed. elastic body

LSR 1:1 silicone mold making operation instruction

1. Cleaning models and fixing

2. Make a fixed frame for the model and fill the gap with hot melt glue gun

3. Spray molding agent for the model to prevent adhesion

4. Fully mix and stir up the A and B according to the weight ratio of 1: 1 (stir in one direction to prevent entering too much air)

5. Put the mixed silicone in the vacuum box and discharge the air

6. Pour the silicone into the fixed box

7. After 8 hours of waiting, the solidification is complete, then removes the model

Precautions

1. Under normal temperature,operation time of adding silicone is 30 minutes, and the curing time is 2 hours.

You can also put into a 100 -degree Celsius oven and complete the curing in 10 minutes.

2. The LSR silicone cannot be exposed to oil mud, rubber puree, UV gel models, 3D printing resin materials, RTV2 molds, otherwise silicone will not solidify.
