Description
The Shin-Etsu CLA-3 is a one-part room-temperature-vulcanizing silicone adhesive supplied in a 20 gram tube for industrial bonding, gasketing, and electronics assembly. The clear, acetoxy-cure formulation builds strength on contact with atmospheric moisture, which makes it a workshop-friendly choice when sustained heat or two-part dispensing is impractical.
Where Shin-Etsu CLA-3 fits in industrial bonding
Maintenance technicians, electronics assemblers, and gasket fabricators reach for this silicone when they need a flexible bond between dissimilar substrates. Glass to metal, ceramic to plastic, and rubber to metal pairings cure under shop conditions within 24 hours, with no clamping fixture required beyond contact pressure. The 20 gram tube format is convenient for small repair runs, prototypes, and field service kits where a cartridge would be wasteful.
How the Shin-Etsu CLA-3 silicone performs
Cured CLA-3 resists temperatures across the standard RTV silicone range, holds dielectric properties suitable for low-voltage electronics, and retains flexibility through thermal cycling. Surface preparation matters: clean substrates with isopropyl alcohol, allow to flash off, then dispense the bead. Acetic acid is liberated during cure, so use the product in ventilated areas and avoid bare-metal contact with sensitive alloys.
