All purpose epoxy paste. Bonds seals and fills fiberglass wood concrete metals and more. PC Products PC-11 PC-11 White Epoxy Paste. PC-11 was formulated as a true marine epoxy, allowing users to bond to wet, dry and fully submerged substrates. PC-11 formulation provides extended working time, for large and critical jobs, which allows the user to reposition work or make changes. High "wet grab" or tack of PC-11 makes overhead and sidewall work easy without drip or sag. PC-11 demonstrates excellent chemical resistance to mild acids, caustics, detergents, gasoline, fuel oil, salt, and fresh water. In cold or cool temperatures, place PC-11 containers near heat prior to using. PC-11 mixes and spreads easier at 80 degree F than at 40 degree F. Any clean smooth flat surface is an excellent surface for mixing and working. A small putty knife or flexible artist spatula are great tools for mixing and applying PC-11.
