HYPRO® 1300X43 LC VTBN X

HYPRO® 1300X43LC VTBNX copolymer is an improved, lower-color version of HYPRO® 1300X43 VTBNX. It has a longer shelf life than the standard version. HYPRO® 1300X43LC copolymer 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 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 copolymer has a random co-polymer backbone with 78.5% butadiene and 21.5% acrylonitrile and multifunctionality. 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.

Application Information

HYPRO® 1300X43LC VTBNX copolymer is typically used in adhesives, sealants, coatings and resin systems based on vinyl esters or methacrylates. It provides the performance benefits of the rubber (toughener, low-temperature and impact resistance), and it reacts into the cured polymer matrix.

Acrylic adhesives, sealants, coatings:

  • Higher T-peel and lap-shear adhesion
  • Higher impact resistance and toughness
  • Enhanced properties at low temperatures
  • Increased resistance to fatigue

Vinyl ester resin, adhesives and composites:

  • Higher impact resistance and toughness
  • Synergistic toughening with vinyl-ester-rubber adducts and other toughening additives
  • Improved compatibility with fiber reinforcement
  • Higher T-peel adhesion to metal

Polymethylmethacrylate (PMMA) composites:

  • Higher toughness
  • Improved compatibility with silica reinforcement

Polymer Characteristics
HYPRO® 1300X43LC VTBNX copolymer has higher acrylonitrile content than HYPRO 1300X33LC VTBNX. The higher level improves compatibility with polar components, fillers and reinforcements. It also improves the miscibility with the resin and increases the flexibility in the resin. It has a slightly higher glass transition temperature.

Storage & Handling

Storage Information
HYPRO® 1300X43LC VTBNX material should be stored in a dry place, in the sealed original containers, at temperatures between +2C and +8C (+35.6°F and 46.4°F). Under these storage conditions, the product has a shelf life of 12 months (from date of manufacture). The products should not be exposed to direct sunlight. Store HYPRO® 1300X43LC VTBNX away from incompatible substances—oxidizing agents, reducing agents, and chemicals that react with methacrylates.
