Selection & Specification Data

Generic Type Two-component, reinforced modified epoxy

Description

Windmastic 304 Primer is a high solids epoxy that forms a dense barrier over steel, concrete, or fiberglass-reinforced epoxy preventing absorption of moisture. It exhibits very good chemical resistance and excellent resistance to mechanical abrasion. It is specifically designed as a primer/barrier coating on wind turbine rotor blades; but may also be used over steel or concrete to prevent corrosion.

Substrates & Surface Preparation

General

Surfaces must be clean and dry. Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating.

Laminate Abrasive - (sand) – sweep to increase adhesion between laminate and coating.

Previously Painted Surfaces

Lightly sand or abrade to roughen and de-gloss the surface. Existing paint must attain a minimum 3A rating in accordance with ASTM D3359 “X -Scribe” adhesion test.
