- 105 ± 4°F (41 ± 2°C)
STORAGE STABILITY
One year from date of manufacture when stored in sealed containers below 75°F (24°C).
CLEANER
Gaco Western's T-5135 thinner.
APPLICATION
PRIMER
None normally required.
MIXING
Mix before application to assure uniform color and consistency.
APPLICATION
Apply by brush or roller as received. For spray application, use as received. Consult Gaco Western's Silicone Spray Guide SG-Silicone for more information.
For cold weather application, keep material stored above 65°F (18°C). Maximum time between coats is 72 hours. Longer recoat times will result in poor intercoat adhesion and delamination.
CLEAN-UP
Clean spray equipment with GacoFlex T-5135 thinner. Recirculate through lines and gun until residual GacoSil is removed.
CURE
Applied coating will cure in 3 to 7 hour depending on temperature and humidity.
CAUTION
GacoSil S-10 contains solvent and is combustible. Keep away from heat, sparks and open flame. Avoid prolonged breathing of vapors and prolonged or repeated skin contact. Use only with adequate ventilation.
