Two-component silicone is distinguished and named for the single component silica gel. This product consists of two components and cures after mixing the two components in the right proportion. Generally divided into condensation type and addition type, the biggest difference between the two is condensation type will release low-molecular substance and addition type will not, so condensation type potting adhesive will shrink during curing and addition type potting will not.
Two – Component condensation type potting : it mainly used in circuit boards, LED power supply, LED outdoor lamps, automotive electronic modules, electrical appliances, light sources, lighting and ancillary devices for potting protection and play the role of sealing waterproof, insulation.
Two – Component addition type potting : it mainly used in circuit boards, LED power supply, LED outdoor lamps, automotive electronic modules, electrical appliances, light sources, lighting and ancillary devices for potting protection and play the role of sealing waterproof, insulation.
