Description
DEMCO EPOX 712 PR is a high-build anti-corrosive primer based on epoxy polyamide resin. It is used as a steel primer for all types of steel structures. Suitable for the petroleum and chemical industries and other industries requiring a high level of corrosion protection for metal.
Advantages
- Provides superior corrosion resistance on metal surfaces.
- Provides excellent adhesion strength and durability.
- Offers excellent resistance to sagging.
- Thanks to its high solids content, the product achieves a high film thickness even in single-pass applications.
Application Areas
- As a steel primer on all types of steel structures
- In the petroleum and chemical industries
- In other industries requiring a high level of corrosion protection for metal
