Formulated to be low viscosity, the resin also enables easy incorporation of fillers for casting purposes or the use of fiberglass for laminating applications. Dalchem 521 Epoxy is excellent as a general purpose adhesive, and is used extensively in woodworking and boatbuilding applications. The resin and hardener will cure to form a hard, high impact resistant casting or adhesive bond that exhibits excellent mechanical properties.
Multipurpose applications include general resin laminating, bonding of parts and casting of foundry patterns, plugs and checking tools.
