Waterborne alkyd primer
1 PRODUCT DESCRIPTION
The product is a high performance single-component water-based acrylic environmental protection coating made ofwater-based acrylic resin and pigment filler.It is an ideal substitute for traditional solvent-based anticorrosivecoatings.
2 RECOMMENDED USE
It is suitable for metal anti-rust coating in foundry, workshop steel structure, industrial equipment, machinery manufacturing, bridge, railway freight car and other industries.
3 FEATURES
- The decorative effect is excellent, and the color is bright and lasting.
- It has good weather resistance, corrosion resistance and mechanical strength.
- Good adhesion and broad applicability.
- Water-based solvent, non-flammable and non-explosive, dries quickly, and is easy to apply.
