Waterborne MIO·Eco-Friendly Intermediate Paint

Waterborne Epoxy MIO Intermediate漆

Name: Water-Based Epoxy MIO Intermediate Coat KF-WM100 - Water-Based Eco-friendly / Excellent Shielding / Full Water-Based System | KeXin New Material
Brand: Kexin New Materials
Availability: InStock

KF-WM100 Water-Based Epoxy MIO Intermediate

KF-WM100 Waterborne Epoxy MIO Intermediate Paint is based on waterborne epoxy resin and waterborne curing agent, with micaceous iron oxide (MIO) pigment added. The MIO flakes align parallel in the coating to form a labyrinth shielding layer that blocks moisture and corrosive media penetration. Water is used as thinner, with VOC approaching zero. It is the core intermediate layer of the waterborne heavy-duty anti-corrosion three-coat system (waterborne zinc-rich - waterborne MIO - waterborne topcoat).

Product highlights

CoreAdvantages

MIO Shielding·Labyrinth Effect

Micaceous iron oxide (MIO) is a flake pigment (particle size 5-30 microns) arranged in parallel overlapping layers within the coating. It forms a labyrinth shielding layer that effectively blocks moisture/oxygen/chloride ion penetration. The coating withstands salt spray for more than 1500h (100 microns single layer). It is the key intermediate layer connecting primer and topcoat in heavy-duty anti-corrosion coating systems.

Waterborne System·Full Supporting Range

Forms a fully waterborne heavy-duty anti-corrosion three-coat system with waterborne epoxy zinc-rich primer KF-WZ500 and waterborne polyurethane topcoat/waterborne fluorocarbon topcoat. Total dry film thickness 280-320 microns, designed service life greater than 15 years in C4-C5 corrosion environments. Helps coating enterprises achieve full-process waterborne environmental compliance.

Single-coat thick film · efficient application

High-solids waterborne epoxy system can achieve 80-150 microns in a single coat without sagging. Pot life at 23 degrees greater than 2 hours, suitable for large-area spraying. Good intercoat adhesion with waterborne zinc-rich primer and waterborne topcoat, no sanding required. Curable at low temperature of 5 degrees, meeting winter coating needs.

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.

Eco-compliant green manufacturing system

All products are RoHS/REACH certified and their VOC content meets national environmental standards. Environmental performance test reports from authoritative third-party testing organizations such as SGS and CTI are provided.

Complete quality control and batch traceability

A comprehensive quality control system is in place from raw material intake to finished product delivery. Each batch of products undergoes rigorous physical and chemical performance testing and coating simulation testing. A batch test report and product quality certificate are included with each shipment.

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

Bake or air dry at room temperature until fully cured according to product requirements. Maintain a uniform oven temperature (±5°C) and gradually increase the temperature to avoid coating defects. For room temperature curing, ensure adequate ventilation and suitable humidity.

Inspection & acceptance

We test all indicators including film thickness, adhesion, gloss, color difference, and chemical resistance. We conduct comprehensive performance testing according to relevant standards. After all tests pass, we issue a test report and quality assurance certificate, and ship the product in dust-free packaging.
