Product Information - TB1221H

TB1221H

TB1221H is a one-component silicone adhesive sealants for the bonding, fix-sealing, coating, and potting of electrical and electronic parts. Conventional de-alcohol silicone RTV rubbers have slow surface-curing and deep-curing properties, as well as unsatisfactory storage stability. The products in the 1220 series show remarkable improvements in all these properties. They dry and cure quickly at room temperature, they are resistant to corrosion, and they have excellent storage stability.
