Non corrosive heat conductive silica gel acc1802
Acc1802 is a non corrosive, one component room temperature curing silica gel. It is a new member of dealkylated curing sealant. When as1802 contacts with moisture in the air, it will quickly solidify into silicone rubber with very strong heat conductivity (2.3W / MK) and certain toughness. As1802 is a non corrosive neutral curing sealant, which does not corrode copper or copper alloy. When fully cured, it has strong adhesion to many substrates.
