Product Characteristics
- Excellent water dilution capability, low odor, free from toluene and xylene, complying with environmental regulations.
- Good stability, can be dispersed at high speeds, resistant to acids and alkalis, with good heat storage, centrifugal, and dilution stability.
- Outstanding film-forming ability, quick surface drying at room temperature, with good wetting and leveling properties.
- Ideal base material for high-temperature waterborne coatings when combined with suitable heat-stable pigments, fillers, or metallic powders.
- The fully cured coating has good thermal stability, excellent weather resistance, and salt spray resistance.
- The fully cured film has good hardness, toughness, abrasion resistance, impact resistance, and chemical resistance.
- Can be used to formulate white, light, and colored paints with low yellowing under high temperatures.
Application Areas
- High-temperature waterborne coatings for home appliances, cookware, stoves, fireplaces, ovens, kilns, flues, chimneys, automotive exhaust pipes, and engines.
- Weather-resistant and anti-corrosion outdoor metal waterborne coatings.
- Waterborne insulating coatings for household appliances (e.g., exterior coating for non-stick pans), electronic and electrical components, and electromechanical products.
- Ideal base material for high-temperature waterborne thermal insulation coatings, fireproof coatings, heavy-duty anti-corrosion coatings, thermally conductive coatings, and insulating coatings.
Typical Physical Data
Curing Conditions
200~280℃ for 10-60min. Higher temperature shortens curing time. Optimal curing is 220℃ for 30min or 280℃ for 10min. The best salt spray and chemical resistance are achieved under these conditions.
Usage Recommendations
1. 1.It is recommended to first prepare waterborne non-resin color paste and then use it in combination with waterborne silicone resin emulsion.
2.The formulated coating has good room-temperature self-drying properties. To achieve excellent heat resistance and physical-mechanical properties, complete curing is recommended at 200-280℃ for 10-60 minutes, with optimal curing at 220℃ for 30 minutes or 280℃ for 10 minutes.
Packaging and Storage
1. Packaging Specification: 50 kg plastic drum.
2. Store in a ventilated, cool place above 0℃, not exceeding 40℃. Transport as non-hazardous goods.
Shelf Life
Store in a sealed container for 6 months. (Each product label will indicate the "best before" date. Storage beyond the indicated date does not necessarily mean the product cannot be used, but the relevant properties should be rechecked to ensure quality).
