Disclosed is a composition for improving the corrosion resistance of metals coated with 2K coatings. The composition comprises a polyol resin having a sulfonyl isocyanate grafted onto the resin. The polyol resins are polyester polyols and acrylic polyols. The grafted resins significantly improve metal corrosion resistance on smooth metal substrates when the grafted resins are incorporated into 2K coating systems.

A xylylene diisocyanate composition includes a xylylene diisocyanate and a 4-methylbenzenesulfonyl isocyanate.

Provided herein is a two-component polyurethane adhesive composition.

The present disclosure relates to an isocyanate composition having excellent storage stability and an optical lens produced from such an isocyanate composition.

A polyurethane-forming system having a viscosity at 25 C. of less than 600 mPas for at least 30 minutes, a gel time at ambient temperature of greater than 60 minutes and a water content of less than 0.06% by weight, based on total system weight, is used to produce composites by a vacuum infusion process. This system makes it possible to produce large composites such as wind turbine blades having excellent physical properties.

An adhesive bond between at least one thermoplastic and an elastomer composition containing at least one polyether having blocked hydroxyl groups as plasticizer. With the adhesive bond, it is possible to bond thermoplastics such as polycarbonate or polystyrene in particular to the elastomer composition essentially without stress cracking and hence reliably and permanently.
