Description

Technical field

[0001] The present invention relates to the field of bonding sealing technologies, and in particular, to a flushing of two-component silicone sealing gum. Background technique

[0002] Silicone materials have more excellent weather resistance, high-temperature, low-temperature, low-temperature resistance, etc., with coupling agents, silicone tackifiers, and surface treatment, can be widely used in various weak applications. Polar material bonding fixation. At present, silicone materials as bonded seals are primarily a single component condensation room temperature vulcanized silicone rubber and a single component additional high temperature vulcanized silicone rubber. Single-compartment temperature sulfurized silicone rubber is simple, contact moisture vulcanization, no other special equipment, but its deep curing is slow, especially in winter, slow curing speed constrains its high efficiency, large-scale bonding application; single group Differential high-tempera...
