Application Instructions
▊ GM-3040 Pure Silicone Resin Coating
Substrate Preparation: Degrease and derust; sandblasting improves adhesion.
Application Conditions: 5°C–40°C; stir well before spraying; can be diluted with 5%–10% water.
Curing Method:Air drying (requires 1 week)Or bake at 220°C for 30 minutes
Packaging & Storage: 20/200KG drums; store in a cool, ventilated area (0°C–40°C); 12-month shelf life.
▊ GM-3041 Water-Based High-Temperature Heavy-Duty Anti-Corrosion Paint
Substrate Preparation:Bare steel requires sandblasting (30–45μm roughness).
Other substrates must be clean and oil-free.
Application Conditions:Temperature ≥5°C, humidity ≤85%.
Two-component mixing ratio: 1:0.085 (must be used within 12h after mixing).
Curing Method: Air drying; recommended film thickness: 200–350μm.
Packaging & Storage: Transported as non-hazardous; refer to label for shelf life.
Precautions
▊ General Requirements
(1)Test substrate compatibility before application; avoid working in rain/snow.
(2)Stir well if sedimentation occurs; clean tools immediately after use.
(3)In case of eye contact, rinse immediately with water.
▊ Special Notes
(1)GM-3040: Recheck performance if stored long-term; high-temperature baking accelerates curing.
(2)GM-3041: Ensure no powdering before recoating; mixed paint requires 20–30 minutes of maturation.
