Hypro 1300X33LC VTBNX
Hypro 1300X33LC VTBNX
Hypro 1300X33LC VTBNX is an improved, lower-color version of the Hypro® 1300X33 VTBNX. It has a longer shelf life than the standard version.
This product 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 1300X33LC VTBNX has a random co-polymer backbone with 82% butadiene and 18% acrylonitrile and is multi-functional. 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 fiber-reinforced polymer composites. The multifunctionality enhances the cross-linking in the cured adhesive, sealant, or coating.
Applications for Hypro 1300X33LC VTBNX
This product is most commonly used in adhesives, sealants, coatings, and resin systems based on vinyl esters or methyl methacrylates. It provides the performance benefits of the rubber (toughener, low- temperature, impact resistance), and it reacts to the cured polymer matrix.
Acrylic adhesives, sealants, coatings:
- Higher T-Peel and lap-sheer adhesion
- Higher impact resistance and toughness
- Enhanced properties at low temperatures
- Increased resistance to fatique
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
Features & Benefits
Hypro Reactive Liquid Polymers set the industry standard for increasing the toughness of epoxy systems. Hypro 1300X33LC VTBNX provides toughness, impact resistance, and low-temperature properties to vinyl-ester or methacrylate resins and composites and to acrylic adhesives.
Hypro VTBNX’s are miscible with the pre-reacted systems, and they form rubber domains when cured.
The improved Hypro 1300X33LC VTBNX has much lower color (Gardner 4 v Gardner 15+) and much better viscosity stability with age and temperature.
It also has the key properties of the standard version:
- Cures via free radicals
- Multifunctional
- Low glass transition temperature
- Optimum balance of butadiene and acrylonitrile – excellent rubber benefits and the compatibility with polar components
