Use restrictions
Reasons for poor curing of addition silicone potting compound:
1. Contact materials: When in contact with the following
ingredients, it will affect the surface curing. The slight one will
only cure incompletely on the surface, and the heavy one will
cause permanent or even incomplete curing:
● Release agent, such as detergent;
● Plasticizers, such as certain plasticizers in insulating plastics,
wires and protective coils;
● Substances containing nitrogen, phosphorus, sulfur and halogen,
such as natural rubber and neoprene;
● Soldering flux, such as rosin;
● Organometallic (lead, tin, mercury, etc.);
● Amine-containing substances, such as polyurethane and epoxy
● Condensation silicone sealant or potting compound
2. Environment: When using, avoid residual oil in the container
or the object being used; avoid some impurities falling into it;
