Waterborne Anti-rust · Self-drying Convenient

Waterborne epoxy estercoatings

KF-WE100 Water-Based Epoxy Ester Paint

KF-WE100 waterborne epoxy ester coating is a one-component self-drying system based on waterborne epoxy ester resin. The coating offers excellent anti-rust performance and strong adhesion. It uses water as thinner with zero VOC and is easy to apply. Widely used for environmentally friendly anti-rust coating of general industrial steel structures, mechanical equipment, and metal products.

CoreAdvantages

Waterborne Epoxy Ester · Self-drying Convenient

Waterborne epoxy ester resin achieves water dispersibility by introducing hydrophilic groups. The one-component self-drying system is ready to use upon opening without on-site mixing of curing agent. The drying mechanism is water evaporation plus oxidative crosslinking. It is easy to apply without strict mixing ratios, suitable for general industrial coating.

Excellent Anti-rust · Solvent-based Alternative

The coating's anti-rust performance is comparable to solvent-based alkyd paint, with salt spray resistance greater than 240h. It has good adhesion to both blasted steel and manually derusted steel. It is the most direct waterborne alternative to solvent-based anti-rust paint, with VOC reduction greater than 90%.

Cost-effective · First Choice for General Industrial Coating

The cost is lower than waterborne epoxy and waterborne polyurethane, making it the most cost-effective waterborne anti-rust coating. Suitable for general industrial anti-rust coating of steel structure factories, storage racks, metal pipes, mechanical equipment, agricultural machinery, etc.

Professional coating technology support services

Kexin has an experienced coating R&D and application team providing full-process support — from substrate analysis, coating selection and process-parameter optimization to on-site application guidance.

Application guide

ApplicationProcess

Surface preparation

Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。

Primer / pre-treatment

Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.

Main-coat application

Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.

Curing process

Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.

Inspection & acceptance

Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
