extend beyond the extension nozzle or aerosol tip to
cure, sealing and protecting the remaining product
from moisture. For reuse, simply remove the cured
product from the tip.
2. For PowerBead dispensers, you may store
remaining product using either the above “silicone
plug” method or using the included plastic cap.

Hi-Temp RTV Silicone Gasket cures on exposure
to moisture in the air. The product dries tack free in one hour
and fully cures in 24 hours. Cure times will vary with
temperature, humidity and gap. Note: The curing process can
cause corrosion to some surfaces, for critical applications use
the Ultra Series silicones.
