04 Jun 2021
Platinum Silicone Rubber Curing Agent Catalyst
1 C-100A and C-100B belongs to platinum addition type cross linking agent and can be approved by FDA after cured, also characterized by non-toxic, odourless, high transparent and well anti-yellowing.The materials can be cured again if low-molecular -weight is strict by request.
This agent are mainly applied to Food Grade and Medical Grade products, such as nipples, cake mold, silicone cookwares, medical silicone tube and so on, also can be used for extrusion products and mobile phone keypad.
