Abatron AboCast 7703-21/AboCure 7703-22 (B) Epoxy Adhesive and Casting Compound
Categories: Polymer; Thermoset; Epoxy; Epoxy, Cast, Unreinforced

Material Notes: AboCast 7703-21/AboCure 7703-21 is an all-purpose clear, low-viscosity, variable-ratio epoxy adhesive and casting compound for electric and structural applications. As an Adhesive: it bonds permanently to metal, wood, glass, fiberglass, ceramics, rigid plastics, concrete, marble, stones, and jewelry. It is excellent to laminate fiberglass, metal sheets, paper or canvas, or any other material for composite structures. As a Dielectric: widely used for potting, encapsulating, dipping, insulating circuits, chips, and other components. As a Casting Resin: for filling, embedments, reproductions, tooling (as is, or blended with fillers such as metal powders, sawdust, etc.). This compound is virtually unaffected by average ambient conditions, soft and salt water, alkalis and diluted acids, several solvents, detergents, oils and greases. Final properties can be modified by changing the AboCast/AboCure ratios: the highest rigidity, hardness, chemical and heat resistance are offered by the 1400/40 ratio. Higher AboCure ratios (up to 100/100 parts AboCast/AboCure) yield increasing flexibility, shock and thermocycling resistance, and adhesion to problem surfaces. The 7703-21 System develops tenacious adhesion to metals, ceramics, wood, fiberglass, masonry, and most materials to form permanent structural and dielectric bonds. Radiation resistance recommends the 7703-21 System in X-ray and other radioactive environments.
