HYPRO® 2000X162 CTB

HYPRO® 2000X162 CTB is a 100% liquid rubber designed to improve toughness, flexibility, adhesion, and impact resistance in thermoset resin systems, including epoxies, vinyl esters, unsaturated polyesters, acrylics, and urethanes. This carboxyl-terminated butadiene homopolymer is primarily used as a reactant with base thermoset resins to enhance product performance. The resulting pre-reacts (adducts) can be incorporated at various levels to meet specific formulation requirements.

Storage & Handling

Handling Precautions
  • HYPRO® 2000X162 CTB is not a primary skin irritant or sensitizer. However, as with any epoxy material, irritation can result from repeated or prolonged contact. The symptoms of this irritation may appear as a mild reddening or a more pronounced rash. It is, therefore, important to avoid skin contact where possible. Butyl rubber gloves, full eye protection and protective clothing are recommended.
  • Skin contact: Wash well with soap and water. Remove contaminated clothing and wash thoroughly before reusing. It is recommended that resin not be removed from skin with solvents since solvents increase contact and encourage penetration. Moreover, solvents of themselves dry and crack the skin.
  • Eye contact: Flush immediately with large quantities of water. Contact a physician.
Storage Condition
  • HYPRO® 2000X162 CTB should be stored in a dry place, preferably in the sealed original container, at temperatures between 2 and 40°C.
  • The product should not be stored exposed to direct sunlight.
  • Keep away from food, drink and animal feeding stuff.
