Product Description
CTPB is a liquid polybutadiene rubber with carboxyl groups at both ends of the molecule, which has excellent cold resistance and elasticity.
The carboxyl end groups can react with epoxy resin, which has a good toughening effect on epoxy resin. Compared with CTBN, CTPB has lower viscosity, better low-temperature performance and flexibility.
Application
The CTPB mainly used as a toughening agent for epoxy resin adhesives and sealants, it can also be used separately for manufacturing sealing materials, adhesives, coatings, elastic fibers, and artificial materials Leather, rubber modifiers, etc.
As propellant
Packing & Storage
Safety instructions:
Storage should be at cool, dry and ventilate. The best condition is among -20 ~ 38℃. Shelf life of 12 months, if expire, still used if up to standard through retest. When transportation should avoid rain, sunlight. Don’t mix with strong oxidizer.
