A, properties and USES

1, rubber pad printing is a two-component RTV silicone rubber, can be at room temperature vulcanization molding, curing time varies with the amount of curing agent, the more the amount of curing agent, curing the faster.

2, condensation type rubber pad printing is used for surface printing, such as plastic hardware products have excellent durable grinding performance, no deformation, no oil and the good properties, such as printing ink transfer.

Third, use process

1. According to the proportion of each component in the formula, to calculate the first to operate rubber head size, and then work out the weight of each group, and in a fixed container.

2. Stir the mixture in the mixer fully, mixing, form a stable, consistent color liquid.

3. The mixed liquid in vacuum processing in the vacuum vessel.

4. Good vacuum rubber mixture has clean the blister mould or crystal mould of sulfide.

Four, packaging, storage and transportation and matters needing attention:

1. This series product base gum with 200 kg, 25 kg, 5 kg and 1 kg packing.

2. The series of products should be sealed storage, and in a cool place, prevent the rain, the sun exposure.

3. This series product is a non-dangerous goods, but should pay attention to in use process, avoid the curing agent contact with skin and eyes. With the right amount of detergent and water, immediately if cleaning, such as the eyes, with flowing water washing at least 15 minutes, and consult a physician.
