Hypro 1300X63 ETBN
Hypro 1300X63 ETBN
Hypro 300X63 ETBN is an epoxy-functional synthetic rubber. It is the reaction product of epichlorohydrin and Hypro® 1300X13 Carboxyl-Terminated Butadiene-Acrylonitrile copolymer (CTBN). It is a 100%-solids, reactive polymer designed to incorporate synthetic rubber into a thermoset matrix by reacting it with conventional epoxy hardeners.
This product provides rubber-toughening benefits in 2K epoxy systems and in heat-cured 1K systems.
In 2K systems:
- Lower-viscosity alternative to epoxy resin adducts with CTBNs
- Alterative to amine-terminated CTBN where there is incompatibility with the amine co-curatives
- Complementary toughener with other toughening agents
In 1K systems:
- Lower-viscosity alternative to epoxy-resin adducts with CTBNs
- Higher Tg to systems with epoxy-resin adducts
Applications for Hypro 1300X63 ETBN
This product acts as an effective toughener at 5-to-20 parts per hundred epoxy resin. It has the highest level of solubility/miscibility with all standard Bis-A, Bis-F, and phenol-novolac resins.
It is miscible with these pre-reacted epoxies, and it forms distinct rubber domains when cured. These micron-size rubber particles provide the key performance benefits:
- Fracture toughness
- Impact and crack resistance
- T-Peel and Lap Sheer adhesion
- Adhesion to oily surfaces
- Durability (fatigue resistance)
- Low-temperature adhesion and toughness
Features & Benefits
Hypro Reactive Liquid Polymers set the industry standard for rubber-toughening epoxy, acrylic, vinyl ester, and unsaturated polyester in neat resins, adhesives, coatings, and composites.
Hypro 1300X63 ETBN differs from typical epoxy-functional elastomeric tougheners. The typical products consist of 50%-to-95% epoxy resin reacted onto the rubber. This product is free of epoxy resin and is 100% reactive rubber.
Hypro 1300X63 ETBN is designed for epoxy adhesives, sealants, molded parts, and composites. The butadiene-acrylonitrile backbone provides toughness, flexibility, low -temperature properties, excellent adhesion, and impact resistance to the cured formulation.
