They offer very good adhesion to both blast cleaned steel and concrete. Both concrete and steel surfaces should be grit blasted.
The vinyl ester is often called a "problem solver" especially for inside tank protection. The vinyl ester is effective against a wide range of chemicals. The temperature resistance is also higher than for most traditional paints.
Vinyl esters are often referred to as linings. The world "lining" in the coating industry is commonly defined as a material used to protect the inside surface of a tank, vessel, or similar structures from highly corrosive or potentially highly corrosive environments.
Vinyl esters are normally two-component coatings applied at normal temperature. They are usually applied in thick coats (2 x 750 microns). The vinyl ester coatings have rather short pot life and should therefore be applied with two-component airless spray equipment.
Benefits
- Very fast curing
- Very good adhesion
- Very good abrasion resistance
- Very good chemical resistance
- Very good solvent resistance
- Can be applied with normal airless spray
- Glassflakes improve abrasion resistance
Limitations
- Short pot life (approximately 45 minutes)
- Overcoating interval: min. 2 hours, max. 24 hours
- Limited shelf-life
- Approximately 6 months at 23oC
- Dependent on temperature during application
- Only to be applied on blast cleaned steel (Sa 2½)
