Asphalt-Modified Polyurethanes Show Advantages in Construction Sealants

Poly bd resins are used in adhesives, sealants, castable elastomers, caulks, membranes, foams, coatings, propellant binders, potting and encapsulating compounds, as well as other rubber-fabricated materials.

June 1, 2000

Poly bd resins, from Elf Atochem North America Inc., Philadelphia, are liquid, hydroxyl-terminated homopolymers of butadiene. The facile reaction of Poly bd resins with curing agents such as conventional di- and polyisocyanates provides an economical route to the preparation of general-purpose elastomers. The unique structure of these resins provides properties that surpass conventional polyether and polyester urethane systems, as well as conventional, general-purpose rubbers.
