Polyester-Modified Silicone Resin R-3038A
Product Description
R-3038A polyester-modified silicone resin delivers outstanding high-temperature resistance, water repellency, and moisture resistance. It also offers excellent electrical insulation, arc corona resistance, weather durability, and chemical stability. Once fully cured, it achieves high hardness (≥3H), high gloss, superior fullness, and exceptional anti-yellowing performance.
This resin is widely used in high-temperature-resistant coatings, making it ideal for household appliances such as electric rice cookers, ovens, bread makers, irons, range hoods, and gas stoves, as well as for temperature-resistant non-stick coatings and specialty coatings.
Technical Specifications
| Index | R-3038A |
|---|---|
| Appearance | Light yellow to colorless transparent liquid, slight milkiness allowed, no mechanical impurities |
| Solid Content | 59±1% |
| Viscosity (25℃) | 350~1000 mPa.s |

Precautions
- Use only dry, impurity-free solvents. Avoid water, pyridine, and sulfur-containing compounds, as they affect adhesion, drying, and film performance.
- Ensure proper ventilation. The resin releases volatile, flammable, and toxic solvents such as xylene. Keep away from open flames and enhance workspace ventilation.
- Maintain cleanliness. Prevent dust, foreign matter, and water contamination during processing.
- Avoid exposure to acids, alkalis, salts, and amine compounds, as they accelerate curing and impact heat resistance and electrical properties.
Storage & Packaging
- Storage: Store in a cool, dry, and well-ventilated area, away from direct sunlight, acids, alkalis, and fire sources. Shelf life: 6 months.
- Packaging: 200kg / 20kg iron drums.
Polyester-Modified Silicone Resin R-3046
Product Description
R-3046 polyester-modified silicone resin offers exceptional high-temperature resistance (250–500°C), water repellency, and moisture resistance. It provides excellent electrical insulation, weather resistance, and chemical stability. This resin can air-dry at room temperature and achieves high hardness (≥1H), good fullness, and high gloss after full curing.
Ideal for use in high-temperature coatings, heat-resistant paints, and weatherproof coatings.

Polyester Modified Silicone Resin : Guide
Polyester Modified Silicone Resin is widely used in high-temperature coatings, anti-fouling coatings, non-stick coatings, kitchen appliances, and more. It serves as a base resin for various special coatings.
Curing Method:
Self-dries at room temperature. For better hardness, cure at:
- 220°C for 30 minutes
- 250°C for 15 minutes
- 280°C for 10 minutes
Adding 10-15% amino resin improves performance but may cause slight yellowing at high temperatures.
