Krefeld, Germany -- Alberdingk Boley has expanded its Albodur line of polyurethane polyols which are 100-percent based on renewable resources, with a new grade Albodur 955 VP.
This material is particularly designed for crosslinking with aliphatic polyisocyanates, and Alberdingk Boley claims it sets new standards in this growing market.
Application areas are interior and exterior light-stable coatings for such products as decorative floors, where good mechanical and chemical resistance is required (flooring of offices and shopping centres, stone carpets, etc, see photo).
Because of its good workability and adhesion properties, the company says Albodur 955 VP also has distinct advantages over two-component spray aliphatic systems. It can be used for metal protection (both for primed substrates and for direct-to-metal) as well as for GRP (fibreglass-reinforced plastic) substrates.
Alberdingk Boley set itself the goal during development of the new polyol to combine excellent processing properties, high cured hardness and reduced hydroxyl content, making possible a cost-optimised aliphatic polyurethane system.
Like all binders in the Albodur product line, the new grade is also based on renewable resources and is characterised by its excellent hydrophobic properties.
According to the coating chemicals company, the product can be crosslinked with all major aliphatic polyisocyanates (hexamethylene diisocyanate (HDI) and mixes of HDI/isophorone diisocyanate).
