GT Products 3100 is a non-slump one-part silicone that cures to a tough elastomer when exposed to atmospheric moisture at room temperature.
GT Products 3100 is a neutral cure (oxime) system and has no offensive odor.
FEATURES
Because no corrosive by-products are
evolved, GT Products 3100 will not corrode
metals and can be used in contact with mortar
and cement. GT Products 3100 may be applied to horizontal, vertical and overhead surfaces without sagging. GT Products 3100 will adhere without a primer to many clean substrates such as aluminum, steel, glass, wood, silicone rubber, and has excellent adhesion to many plastics. GT Products 3100 features excellent resistance to heat, cold, water, ozone, and ultraviolet rays. It remains flexible and does not crack or harden. GT Products 3100 contains no solvents.
It has negligible shrinkage during cure; GT Products 3100 is useful over a temperature range of –75°F to 450°F for extended operation and for intermittent periods up to 500°F

GT Products 3100 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 3100 is applied. GT Products 3100 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 77°F and 50% RH GT Products 3100 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 3100 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. No odor or corrosive by-products given off during the cure of GT Products 3100.
Caution GT Products 3100 is not recommended for use on calcareous surfaces or on materials that bleed oils or plasticisers.
Storage and Shelf Life GT Products 3100 has a shelf life of 12 months when stored in the original unopened containers at or below 90°F.
Health and Safety
GT Products 3100 is sold for industrial use only. Uncured product will irritate the eyes. In case of contact with the eye, flush with running water for 15 minutes and call physician. Uncured GT Products 3100 may also irritate the skin. Removal by wiping with dry cloth or paper followed by washing with soap and water is recommended. Wearers of contact lenses should not handle lenses unless the sealant has been completely removed from fingertips.; sealant will transfer to lens and cause severe eye irritation.
