Description: In some cases, the AB component is partially solidified after mixing, the surface and interior are not dry, the hand adhesion is serious, and the product qualification rate is low.

Explore the reason:
① The dosage of curing agent is insufficient and the curing reaction is incomplete;
② Silicone rubber of component A and curing agent of component B are not fully stirred evenly, and the reaction is not sufficient;
③ Mold type problem, which may affect the solidification of impurities or dust covering its surface;
④ The operating environment is too dry and the humidity is not enough.

terms of settlement:
① According to the operation manual provided by the silicone rubber manufacturer, only by adding silicone rubber and curing agent in proportion can the crosslinking reaction be sufficient, and only more can not be less (not the maximum value specified by the manufacturer);
② After the curing agent and silica gel are mixed, they must be stirred evenly for the curing reaction to be sufficient;
③ Clean the dust and impurities on the mold surface;
④ Look for an operating environment with relatively high humidity to react.
