Araldite® GZ 7488 V-40 Resin is a very high molecular weight epoxy based on bisphenol A dissolved in primarily propylene glycol monomethyl ether acetate. Since a film forms without the use of hardener, it produces outstanding coatings by air or force drying. In addition, the high hydroxyl content of the resin permits reaction with urea-melamine, and phenolformaldehyde crosslinking resins to produce excellent baking finishes. Coatings based on Araldite® GZ 7488 V-40 Resin exhibit excellent adhesion, flexibility, impact and abrasion resistance, and chemical and corrosion resistance. The unique feature of the resin is its low degree of branching, leading to greater flexibility than the very high molecular weight resin Araldite® GZ 488 Resin. The more linear structure results in higher solids than the Araldite® GZ 488 V-32 Resin solution.

Storage
Araldite® GZ 7488 V-40 Resin is supplied in 400 pounds steel drums. It should be stored in a dry place, in the sealed original container, at temperatures between 2°C and 40°C (36°F and 104°F). Under these storage conditions the shelf life is 6 years (from date of manufacture). The product should not be exposed to direct sunlight.
