A silica gel, hand-board model USES

Toys, craft gifts, hand made with the copy, model, product development, and other products of simulation material; Widely used for clay, plaster, resin, ABS, PU, AB water copy; Is also used to copy hand-board model and small batch of products.

2, hand-board model silicone product features

This series product is A two-component condensed type liquid silicone rubber, A component is the flow of liquid, team B is curing agent; This product has good liquidity, low viscosity easy operation; After curing burn resistant, high temperature resistant, corrosion resistance, solvent resistance, and the tensile and high intensity, crack resistance, line shrinkage of small, rolling over more advantages.

Note: the parameters in the table colloid viscosity, color, transparency, hardness, etc according to the customer's demand.

Four, hand-board model silica gel using method

When using the rubber are taken from the packaging barrels, said after the required weight of rubber, the rubber: curing agent = 100: the weight ratio of 2, stir well, after vacuum exhaust bubble or hot air bubble, inject clean mold frame, placed at room temperature, the glue material injection molding using after curing.

Five, hand-board model silicone matters needing attention

1, this product curing speed has close relationship with the environment temperature, the higher the temperature, the faster the curing; The user can according to the gas temperature of high and low, appropriate adjustment of dosage of curing agent, can achieve the ideal curing speed.

2, such as replication products for ceramic, 815 resin, ABS material, wood products, metal materials, such as the original plate, its original plate surface should be used release agent or with barbecue mode method, then filling mould, avoiding sticking later.

3, the series of products of the two components should be sealed storage, placed in a cool place, avoid sharp.

4, the shelf life of the series of products for six months; Storage period such as viscosity thickening, stir well after use, its performance remains the same.

5, this series product is a non-dangerous goods, but in use process, such as curing agent contact with skin, wash with detergent and water. Such as curing agent for the eyes, immediately wash with clean water for at least 15 minutes, and consult a doctor.

Six, hand-board model silicone packaging and transportation

This series product packaging in plastic bottles or iron drum, the specifications are as follows: 1 kg, 5 kg, 25 kg, 200 kg packaging, according to the transport of dangerous goods.
