Differences between water-based primer and topcoat

Water-Based Primer

Water-based primer is short for water-soluble eco-friendly metal protective primer. Composed of water-based resin, lead-free pigments, water and other materials, it features fast drying and excellent protective performance, serving as a base coating for metal substrates.

This coating can be applied via dipping, flow coating, spraying and other methods. It is suitable for finishing metal substrates in industrial equipment, transportation vehicles and civil products, and especially ideal for surface protection of export steel products.

Below, Runli New Materials shares knowledge about water-based primer.

- Primer mainly fills pores, increases film thickness, achieves decorative effects and reduces topcoat consumption. It features good filling properties, sandability and hiding power.

- Topcoat mainly provides decoration and protection, with performance such as gloss retention, color retention, hardness, adhesion and leveling.

3. Price Difference Between Primer and Topcoat

Primer is cheaper than topcoat. Under equal conditions, primer usually costs about two-thirds of topcoat. Using primer in construction reduces topcoat usage and cuts overall costs.
