- Suggest that the consumer use the liquid injection molding machine to inject into the mold and manufacture products.
- The two components of A and B must be completely mixed by machine according to the weight or volume ratio of 1:1. The vulcanization time is determined by the molding temperature. At high temperature conditions, a short time is required for product forming. If the silicone product is thick and large, it takes longer time to mold. After vulcanization, the mold can be disassembled.
3. If the machine is shut down for a long time (more than two days), either inject component A or component B into the mixing section alone. Or remove the static mixer of the injection molding machine immediately, seal and store it in a low temperature (< 1℃) environment, or clean up the remaining rubber.
- Packaging, Storage and Caution:
1. This series of product is packed in 20 kg/plastic straight pail or 200 kg/metal drum, with plastic liners.
2. Products should be stored in sealed condition, kept it in a cool place and avoid rain and sun exposure.
3. This series of products are non-dangerous goods. The valid period is 1 year. If the products exceed the storage life, it can be re-tested to prove the curing speed is acceptable, if so, it can be used.
4.To prevent cure inhibition, try to avoid contact with tin compound (most condensation silicone contain tin compound catalyst) amines, sulfur and phosphorus compounds and some metal salts.
5. In this series, component A contains catalyst and component B contains cross-linking agent. When products from different manufacturers are used, tests shall be carried out to avoid cross-linking reaction.
