LK-E37 RESIN
Hydroxyl functional methyl phenyl silicone resin for industrial coatings.
What is methyl phenyl silicone resin : LK-E37 RESIN
The LK-E37 RESIN is a high-performance methyl phenyl silicone resin designed for superior heat and corrosion resistance. With a hydroxyl functionality of 60% in xylene, this resin is ideal for high-temperature applications as it contains higher phenyl. It offers exceptional durability, maintaining film integrity even after five quenching cycles at 650°C, each lasting one hour.
The resin is functionally air-dry at room temperature but achieves complete crosslinking with heat curing at 180°C for 30 minutes. When formulated with inorganic pigments like black oxide or aluminum oxide,
it delivers tack-free finishes at room temperature within 30 minutes and hardens further with heat cure. The addition of LK-SILYN AP 32 enhances crosslinking and acts as an adhesion promoter, boosting overall performance. This makes LK-E37 RESIN an essential ingredient for heat-resistant coatings, ensuring unmatched thermal stability and long-lasting adhesion under extreme conditions.
This innovative resin enables formulations to tolerate temperatures up to 600°C, making it a go-to choice for industrial, automotive, and aerospace applications.
Key features:
- Advanced Thermal Stability- High heat resistant (600 0C with black and aluminium pigments).
- Excellent weather and corrosion resistant.
- Improved flexibility and good solvent resistant.
- Both air dry and heat dry curing possible.
- Excellent colour retention and gloss finish.
- Good adhesion over the heat.
