Material Notes:
A low viscosity, clear amber, unfilled adhesive, recommended for use with activators D or W. C-4 with Activator W offers maximum versatility in that differing degrees of flexibility can be achieved by varying the mixing ratios within recommended limits. C-4 with Activator D is useful where an adhesive with a low mixed-viscosity is needed. It may also be used for fiberglass laminating or casting.Information provided by Ellsworth Adhesives.
