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. Ambient temperature 5-40°C, relative humidity...<85%。

Primer/Pretreatment

Select the appropriate primer or pretreatment based on the substrate and product system. Strictly control the film thickness by mixing according to the product ratio. Proceed to the next process after the primer has dried.

Main coating application

Apply the main coating according to the process requirements. Strictly control parameters such as film thickness, temperature, and humidity. Ensure a uniform coating free of sagging and pinholes.

Curing process

Bake or air dry at room temperature according to product requirements. Increase oven temperature gradually and evenly. For room temperature curing, ensure adequate ventilation and humidity.

Inspection and Acceptance

We test all indicators, including film thickness, adhesion, and gloss. Once all indicators pass, we issue a test report and quality assurance certificate, and ship the product in dust-free packaging.
