Technical documents and conditions of use
See the technical documents below for specification sources and conditions. Verify the exact grade and document version before application. Specification sources
A system application handbook is available; an individual TDS or SDS for this product has not been supplied. Use the handbook for system selection only. Confirm the specification, film thickness and acceptance criteria with the technical team for the exact model and service conditions.
Verify performance and service-life statements against the relevant reports, specimen preparation, test standards and service conditions. Service-life figures without supporting reports are not durability guarantees; site photographs do not replace film-thickness testing or project acceptance records.

Features
- Verify weathering, adhesion and protective-layer requirements for the selected grade, substrate and exposure. Laboratory results do not establish a fixed outdoor service life.—Confirm adhesion and compatibility with the existing coating through grade-specific documentation and substrate trials.
- Review the grade-specific SDS, emissions data and ventilation requirements before use. Wear appropriate protective equipment. Drinking-water or food-contact applications require specific evidence and approval for the intended use.
- Select the coating according to actual mechanical loads, chemical media, concentration, temperature and exposure. Confirm suitability by testing and establish an inspection and maintenance plan.
Applications
Directly covered in epoxy or polyurethane paints, interior walls, outer walls, epcoat priority for substrates, polyurethane topcoat fittings, polyaspartic polyurea topcoat protection
Storage
This product is combustible. Store at or below 40 degrees Celsius in a cool, dry, ventilated place away from ignition sources. Shelf life: one year.
