Description of rtv silicone rubber for GRC concrete products

HY- E series addition molding silicone is generally named two-components silicone

rubber, Part A and part B. It features an exceptional fluidity and good operability.

The mixing ratio is 1:1 (10:1),mainly be suitable for making molds application.

Typical Applications of rtv silicone rubber for GRC concrete products

HY- E series addition molding silicone could be mainly used for making concrete

stones, wax molds, PU molds, resin molds, gypsum casting, candle molding and

chocolate , candy and any other FDA food product mold making, prototyping etc.

Characteristics of rtv silicone rubber for GRC concrete products

*low shrinkage (less than 0.1% )

*high tensile and tear strength with high copy times

*easy for operation (mixing ratio at 1:1 /10:1)

*very good flow and easy for pouring operation

*Fast and non-shrink cure at room temperature which can be accelerated considerably by the application of heat

OPERRATING INSTRUCTION:

1.Stir part A and part B with right mixing ratio evenly. (E630# is 1:1) and get the mixture for vacuum-pumping.(If there is no vacuumizer,you can just pour the mixture slowly from the corner so that less bubbles caused).

2.Enclose the product (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 product.

4.Pour the mixture with correct mixing ratio into the model frame.

After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold .

SHELF LIFE:

Twelve (12) months from date of shipment when stored at 24°C in original unopened packages.

PACKAGE:

Packed in clean 25kg/pail, 200kg/pail.
