Armstrong C-7/H20 Epoxy Adhesive

A clear, unfilled, medium viscosity adhesive recommended for use with any Armstrong Activator. Physical property data included covers C-7 used with Activators W and H-20. All other Activators may also be used to achieve specific characteristics in the completed bond- see appropriate Data Sheet for details. C-7 with Activator W offers maximum versatility in that differing degrees of flexibility can be achieved by varying the mixing ratios within the recommended limits. C-7 with Activator W meets the requirements of Navy Specs. XWS15351 and WS 09125C. C-7, when used with Activator H-20, offers a tough yet rigid bond.
