I am developing a two-component reactive adhesive and need some guidance on polyol selection. Can you provide information on the performance expectations of different polyol components? The variety of hydroxyl-containing
A particular application will require me to bond a variety of optically clear polymers to each other and to glass. What adhesive options are available?A particular application will require me
A lot of recent discussion has focused on making construction adhesives and sealants green by eliminating formaldehyde, plasticizers or solvents. Are there similar alternatives for the coatings that are often
What are hot-melt polyurethane reactive adhesives used for?
January 26, 2001
Although hot-melt polyurethane reactive (HMPUR) adhesives have been available for 25 years, their novel properties and the development of diverse products have accelerated their recent growth.
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.

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.
