Product Feature and Application
Key Features
- Lowers Viscosity: Effectively reduces the viscosity of epoxy resin systems without solvents.
- Improves Weather Resistance: The branched structure provides excellent weatherability, UV resistance, and gloss retention.
- Enhancing Flexibility: Increases the flexibility and impact resistance of cured films.
- Hydrolytic Stability: The sterically hindered ester bond offers resistance to hydrolysis and chemicals.
Main Applications
- Reactive Diluent: For epoxy resins in solvent-free high-solid coatings.
- Resin Modifier: Used in acrylic, polyester, and alkyd resins to improve flexibility and durability.
- Coatings: Ideal for automotive topcoats, can coatings, industrial primers, and heavy-duty anti-corrosion coatings.
Production Details
Glycidyl Neodecanoate is produced via the esterification of neodecanoic acid with epichlorohydrin.
The process typically involves a ring-formation step in the presence of a basic catalyst, followed by purification to remove ionic impurities and water, ensuring high epoxy content and low color.
Product Qualification
The product complies with standard industrial specifications:
TSCA (US)
Listed on the Toxic Substances Control Act Inventory.
Regulatory Status
Active in global chemical inventories (REACH, etc.).
Packaging
Compliant with UN regulations for safe transport.
Deliver, Shipping and Serving
- Packaging Options: Available in 25 kg pails, 200 kg steel drums, 1000 kg IBC totes, or ISO tanks.
- Storage Conditions: Store in a cool, dry, well-ventilated area away from sunlight and heat. Keep container tightly closed.
- Shelf Life: Typically 12 months from date of manufacture when stored properly.
- Logistics: Classified as a stable, non-dangerous good under specific shipping conditions, though it is combustible.
FAQ
Q: Is Glycidyl Neodecanoate a solvent or a reactive diluent?
A: It is a reactive diluent. Unlike solvents, it chemically reacts and crosslinks into the final polymer network, reducing VOC emissions and improving film properties.
Q: How does it improve weather resistance?
A: Its highly branched "neodecanoate" structure creates a steric hindrance effect, protecting ester bonds from hydrolysis and UV degradation.
Q: What are the handling hazards?
A: It can be a skin sensitizer and irritant. Proper safety equipment (gloves, goggles) should be used. Avoid strong oxidizing agents and acids.
