PITTCOTE® 300E Coating

Description

PITTCOTE® 300E Coating is a liquid-applied, moisture-cure vapor retarder coating specifically formulated for use with FOAMGLAS® insulation and self-sealing PITTWRAP® jacketings. Upon curing, it forms an elastomeric layer that provides a protective barrier against moisture. Suitable for above-ground applications under a UV-resistant finish or for direct-buried applications, it can be applied by brush, trowel, or spray.

Features

Moisture-Cure Vapor Barrier: Forms an elastomeric layer that effectively resists moisture penetration.
High Solids Content: Ensures a durable, thick coat with each application, suitable for demanding industrial uses.
Versatile Application Methods: Can be applied by brush, trowel, glove, or spray (spray grade available by special order).
Weather Resistance: Offers good resistance to weather, but should be covered with a UV-resistant finish for prolonged exposure.

Certifications & Compliance

Application Standards:
- Must not be used over asphalt primers or with PITTWRAP® HS jacketing.
- For specific chemical exposure conditions, consult Owens Corning for compatibility.
Environmental Compliance:
- Store in heated areas to prevent freezing in cold weather; do not store above 38°C (100°F).
