Versamid® 280 B-75

Versamid® 280 B-75 is a polyamide/epoxy adduct in n-Butanol designed for reaction with solid or liquid epoxy resins.

Key Features and Benefits:

  •  Good flow and leveling properties
  •  Low moisture sensitivity during cure
  •  Excellent solvent and chemical resistance properties
  •  Excellent compatibility with solvent-free liquid epoxy resins

Chemical Composition: Polyamide/epoxy adduct in n-Butanol

Application Properties:

Versamid® 280 B-75 is a polyamide/epoxy adduct in n-Butanol designed for reaction with solid or liquid epoxy resins. It offers excellent compatibility with Bisphenol A-based epoxy resins allowing normal induction times to be reduced and occasionally be eliminated.

Epoxy resin systems based on Versamid®280 B-75 provide unusually good flow and leveling properties and low moisture sensitivity during cure. Coating formulations containing Versamid® 280 B-75 have fast drying times similar to Versamid® 125 and show excellent solvent and chemical resistance properties compared to Versamid® 140.

Versamid® 280 B-75 is suitable in maintenance coatings, primers, and enamel paint formulations. It provides excellent compatibility with solvent-free liquid epoxy resins for formulation of high solids coatings. Coating formulations based on Versamid® 280 B-75 and Versamid® G-2000 meet the stringent requirements outlined in US Navel Specifications Mil P-24441 for corrosion-resistant primers and topcoats. Versamid® 280 B-75 and epoxy resin systems are recommended for applications such as industrial maintenance coating applications, primers, enamel paint formulations.

Package, Storage, Handling:

Versamid® 280 B-75 may absorb moisture and carbon dioxide if left in open containers, which may result in an increased viscosity and some foaming when curing epoxy resins. Therefore, it should be kept in tightly closed containers when not in use and stored in a cool, dry place. Properly stored and protected, an unopened container of Versamid® 280 B-75 should have a shelf life of two years.
