Pennsylvania-based manufacturer Cardolite has added three new polyol products , and the same number of new bio-based grades, to its range of polyurethane adhesives, sealants and coatings derived from cashew nutshell liquid (CNSL), a renewable non-food chain oil.

According to the company, all three new products are suitable for floor and industrial coatings as well as for being used as structural adhesives and sealants in construction, transportation and industrial assembly. However each has its own attributes. One of the new products combines high glass transition temperature, with high tensile strength and excellent bond strength, even when bonding with aluminum substrates. The other two are low in color and viscosity, with both providing high strength according to the company. One product adds flexibility to that strength for more toughness, while the other includes high strength and high resistance to UV light.

Cardolite reports that, in addition to producing CNSL-based polyol as a viable alternative to those based on petrochemicals, it also focuses on using the same bio-based oil for the production of epoxy, amine, and phenolic functional products for the coating, adhesive, friction, foam, and composite industries.
