AWS Roof Coatings: Elastomeric Roof Coatings Fast Set Urethane 530

PRODUCT DATA SHEET

Fast Set Urethane 530
Polyurea Hybrid

DESCRIPTION

Fast Set Urethane 530 is for use as a fast curing high build protective coating over polyurethane foam insulation, metal roofing and other suitable substrates. It may also be used as a base coat with granule for vehicular and pedestrian decks.

ADVANTAGES

Superior Protection - forms a durable, weather resistant "rubber-like" seal.
Excellent UV protection.
Superior adhesive and cohesive strength.
Reduces daily expansion and contraction (thermal cycling) of roofing substrates.
Excellent reflective properties which help to reduce cooling costs. Prevents premature degradation.
Superior elongation and tensile strength.
Superior resistance to dirt pick-up.

BASIC USES

Fast Set Urethane 530 was specifically developed as a protective coating for sprayed-in-place polyurethane foam roofing. With excellent adhesion, Fast Set Urethane 530 may be used as well for protection of conventional commercial/industrial surfaces. Contact American WeatherStar for specific substrates and conditions.

INSTALLATION

All surfaces to be coated must be cleaned properly. Power washing is recommended. Any existing coating must be checked for good adhesion. Before application, any loosely adhered coating must be removed and bare surfaces must be prepared, cleaned and checked for compatibility.

Stirring may be required to ensure uniformity of the material, particularly if products have been stored at temperatures outside of the recommended range.

Apply with plural component airless equipment. Material must be maintained at 170°F during application. For best results maintain pressures at or above 2,500 psi. May apply up to 64 mils in one pass.

WARRANTY

American WeatherStar warrants that the material supplied will meet or exceed physical properties as published. The contractor guarantees that workmanship will be free of defects in coating application. Since performance of previously installed substrate is beyond the control of American WeatherStar or the contractor, requests for additional warranty coverage shall be subject to prior approval by American WeatherStar.

MAINTENANCE

Periodic maintenance of all American WeatherStar products, including cleaning, will ensure extended service life and maintain reflectivity.
