GT Products 2100 Red will adhere to most clean surfaces without additional preparation. Mild abrasion of rubber surfaces will usually improve adhesion. A preliminary test should be made on each new substrate. Surfaces should be thoroughly cleaned with a suitable hydrocarbon solvent such as mineral spirits, naphtha, MEK, etc. Solvents must be wiped from the surface before GT Products 2100 Red is applied. GT Products 2100 Red cures on exposure to the moisture in air. Cure time increases with confinement and cross sectional thickness and decreases with increased humidity and temperature. Curing above 150°F will reduce physical properties. At 77F and 50% RH GT Products 2100 Red will skin over and become tack-free in 10-20 minutes. Tooling and removal of masking tapes should take place prior to this time. GT Products 2100 Red should be applied in a less than ¼ inch diameter bead to assure a complete cross section cure. Metal to metal bonds should not overlap more than 1 inch. The odor given off during the cure of GT Products 2100 Red is acetic acid and disappears when fully cured.
