Product Feature and Application
Features
● Hydrophobicity: The bulky branched chain imparts excellent water resistance.
● Alkali Resistance: Offers superior resistance to hydrolysis and saponification.
● Flexibility: The homopolymer has a low glass transition temperature (Tg) of approx. -3°C, providing internal plasticization and flexibility.
● Weatherability: Enhances the durability and UV resistance of finished polymers.
Applications
● Coatings & Paints: Used in high-durability decorative paints, plasters, and industrial coatings.
● Adhesives: A key component in wood glues, pressure-sensitive adhesives, and sealants, improving wet adhesion and water resistance.
● Construction: Adds flexibility and chemical resistance to waterproofing systems and construction materials.
● Food Contact: Approved for use in adhesives and paper coatings in specific food contact applications (FCN No. 93).
Production Details
Vinyl neodecanoate is typically synthesized via transesterification of vinyl acetate with neodecanoic acid.
It is supplied with a polymerization inhibitor (e.g., 5 ppm monomethyl ether hydroquinone) to prevent premature reaction during storage and transport.
Product Qualification
Regulatory
Listed under the US EPA TSCA Inventory.
Food Contact Status
Effective Food Contact Substance Notification (FCN 93) for use in adhesives (21 CFR 175.105) and paper coatings (21 CFR 176.180).
Environmental
Classified as environmentally hazardous to aquatic life (H400, H410).
Delivery, Shipping And Serving
- Transport Information: Classified as UN 3082, ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S., Packing Group III.
- Packaging: Available in various sizes, from small lab units (100g, 1L) to industrial drums (typically 180 kg) and bulk containers.
- Storage: Store in a cool, dry, well-ventilated area away from strong oxidizers, copper, and zinc. Keep containers sealed and protect from moisture. Stainless steel or lined drums are recommended.
FAQ
Q: Is Vinyl Neodecanoate soluble in water?
A: No, it is insoluble in water and floats on water due to its hydrophobic nature and lower density.
Q: What materials are incompatible with this monomer?
A: It is incompatible with strong oxidizing agents. Copper and its alloys will inhibit polymerization, while zinc can cause discoloration.
Q: Is this product suitable for food contact applications?
A: Specific formulations and grades of vinyl neodecanoate copolymers are approved for food contact applications under FDA FCN 93, with limitations on temperature and food type. Always verify the specific grade's certification.
Q: What is the main benefit of using this monomer in paint?
A: It acts as an internal plasticizer, providing flexibility without needing external plasticizers that can leach out. It also greatly improves the paint's resistance to alkali and water, making it ideal for exterior masonry coatings.
