Hypro® 1300X43LC VTBNX
Hypro 1300X43LC is a low-molecular-weight, methacrylate-functional liquid rubber. It is a 100%-solids reactive polymer used primarily as an additive in acrylic adhesives, sealants and coatings and in vinyl esters.
The butadiene-acrylonitrile copolymer backbone provides improved adhesion, toughness, flexibility, low-temperature properties, and impact resistance. As a component in free-radical cured systems, the VTBNX is incorporated via the vinyl-methacrylate functionality.
Hypro 1300X43LC VTBNX has a random co-polymer backbone with 78.5% butadiene and 21.5% acrylonitrile and multi-functionality. The butadiene provides rubber properties and extends the flexibility and adhesion to low temperatures. It also contributes excellent resistance to moisture, acids and bases. The acrylonitrile provides compatibility with polar additives and improves adhesion to oily metal and to the fiber-reinforcements in polymer composites.
The multifunctionality enhances the cross-linking in cured adhesives, sealants and coatings.
