FAQ

常见问题

Which substrates is it suitable for?+

Suitable for sandblasting and rust removal up to Sa2.5 grade on carbon steel and cast iron surfaces. The substrate must be free of oil, rust, and old paint; a roughness of Rz40-75μm is optimal.

Why can't it be directly exposed to the outside?+

Epoxy resin is not resistant to ultraviolet light and will chalk with prolonged exposure. A complete coating system must be formed by combining an epoxy micaceous iron oxide intermediate coat and a weather-resistant topcoat.

What primers or topcoats are needed?+

We recommend using the same series of primers and topcoats from Kexin to ensure coating system compatibility and optimal performance. Kexin technical engineers can design a complete primer-intermediate-topcoat system solution free of charge based on your specific working conditions.

How can I get samples and a quote?+

Free samples are provided for standard products (shipping costs borne by the customer), along with TDS and MSDS technical data. For bulk purchases, please contact 400-901-0757 or 13531350189. Samples start from 1kg, and bulk orders start from 20kg.

How can I choose the right product model based on my working conditions?+

Choosing the right coating requires comprehensive consideration of the substrate type, operating environment (temperature/humidity/chemical media), corrosion resistance requirements (ISO 12944 C1-C5M), application conditions, and budget. We recommend contacting our technical engineers at 400-901-0757 for professional selection guidance and free sample testing.

Minimum order quantity and delivery time?+

Sample orders start from 1kg, while regular product orders start from 20kg. In-stock products will be shipped within 48 hours, and customized products will take 3-7 business days. Door-to-door delivery is available within the Pearl River Delta region.

Construction Guide

施工流程

Surface treatment

Thoroughly clean the substrate to remove oil and rust. Sandblast steel to Sa2.5 grade. Perform surface pretreatment according to product requirements to ensure substrate cleanliness. Ambient temperature 5-40°C, relative humidity...<85%。

Primer/Pretreatment

Select a suitable primer or pretreatment based on the substrate and product system. Strictly control film thickness by mixing according to the product ratio. Proceed to the next process after the primer has dried. Apply a reinforcing pre-coat to critical areas.

Main coating application

Apply the main coating according to the process requirements. Strictly control application parameters such as film thickness, ambient temperature and humidity, and flash-off time. Ensure a uniform coating free of runs and 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 and 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.
