Detailed Product Description:
#77 is a general purpose orthothalic polyester laminating resin. It has low viscosity for rapid wet-out of fiberglass reinforcements but has an added thickening agent that gives it resistance to drainage on vertical surfaces.
This resin is wax-free (does not surface cure) so no sanding is required between laminating stages, but its cured surface will remain tacky.
Viscosity: 4,000 centistokes
Density: 9 lbs/gallon
Chemical Family: Orthothalic, polyester
Can be an eye and skin irritant.
For best results use at 70ºF or above.
Comes packed in 1 gallon can.
