LOW-NCO POLYISOCYANATE COMPOSITIONS

A polyisocyanate composition can include an aliphatic polyisocyanate resin having a weight average molecular weight of from 1000-6000 g/mol based on gel permeation chromatography. The aliphatic polyisocyanate resin can include a blend of at least two different aliphatic polyisocyanates and can inclu...

More Information
Summary:A polyisocyanate composition can include an aliphatic polyisocyanate resin having a weight average molecular weight of from 1000-6000 g/mol based on gel permeation chromatography. The aliphatic polyisocyanate resin can include a blend of at least two different aliphatic polyisocyanates and can include less than 50 wt % of a cycloaliphatic polyisocyanate based on a total weight of the aliphatic polyisocyanate resin. The polyisocyanate composition can have an NCO % of from 2 wt % to 18 wt % based on ISO 11909:2007. The polyisocyanate composition can include from 84 wt % to 100 wt % solids.
