GM-Ⅰ-Ⅱ-Ⅲ Special Anti-Corrosion Series
The GM series offers exceptional corrosion resistance: GM-Ⅰ withstands harsh chemicals (6+ years), impacts/bending, and extreme temperatures (-40℃~150℃), with 100% closed-cell eco-safe formula. GM-Ⅱ, designed for color steel tiles, features UV resistance, anti-yellowing, and easy application. GM-Ⅲ utilizes advanced technology to prevent yellowing (500h fade-free), combining aesthetics with durability. All variants are solvent-free, potable-water-certified, ideal for chemical, marine, and municipal applications.

Construction Guidelines
▊ Surface Preparation
Clean the substrate thoroughly to remove oil, grease, and rust; ensure it is dry (moisture content ≤ 8%).For cement substrates, repair any cracks. For metal substrates, sandblasting or grinding is recommended.
▊ Coating Preparation
Mix evenly using an electric stirrer and let stand for 10-15 minutes.For Type III, apply Type I primer first (allow 24-hour drying interval).
▊ Application Methods
Apply by brush, roller, or spray, with a single-layer thickness of 0.1-0.2 mm and a total thickness of 0.3-0.5 mm.Allow a 24-hour interval between coats (at room temperature, 25℃).
▊ Environmental Requirements
Temperature: 5°C–35°C, humidity ≤ 85%.Avoid application during rain or snow.
Precautions
(1) Wear protective gloves, masks, and goggles during application, and ensure adequate ventilation.
(2) After construction, promptly clean tools with dedicated thinner to prevent coating solidification.
(3) Use protective equipment such as gloves, masks, and goggles during application.
(4) Maintain proper ventilation at the worksite to avoid inhaling harmful fumes.
