ALDOPRIME 624 is a fast drying rust inhibiting primer designed also as a tie coat for dusty or porous surfaces to improve adhesion of the base coat products. ALDOPRIME 624 has been formulated to have exceptional adhesion to a diversity of substrates. ALDOPRIME 624 penetrates into the surface and provides good anchorage for base coat product in addition to inhibiting rust on oxidized surfaces. Once the topcoat has been applied, ALDOPRIME 624 enhances the properties of topcoat and provides increased resistance to mechanical damage and chemical attack.
ALDOPRIME 624 was specially formulated as a primer coat for rusted metal panels, weathered surfaces or porous materials. ALDOPRIME 624 has an excellent adhesion to a variety of substrates, such as metal, BUR, asphalt, wood, concrete, masonry and polyurethane foam. When used as a black product, ALDOPRIME 624 has been used as an insulator coat for warming roof surfaces before applying sprayed in place polyurethane foam or coating basecoat. Due to low solids and low dry mil thickness, ALDOPRIME 624 is not recommended as a coating product in itself. Apply base coat as soon as possible after primer cures.
