    摘要： The present disclosure describes a method of manufacturing a one-component coating composition. The method can include combining a water-containing additive with a non-reactive resin to form a grinding dispersion. The method can also include grinding the grinding dispersion to a Hegman value of at least 4 to form a ground dispersion. A drying agent can then be added to form a dried slurry. A silane-modified polyurea can be added to the dried slurry to form a one-component coating composition.

    摘要： A polyisocyanate resin can include from 25 wt % to 50 wt % of a first cycloaliphatic polyisocyanate and from 50 wt % to 75 wt % of a flexibilizing component based on a total weight of the polyisocyanate resin. The flexibilizing component can include a linear aliphatic polyisocyanate having a number average isocyanate functionality of from 2 to 3 based on gel permeation chromatography and an isocyanate-terminated reaction product of a second cycloaliphatic polyisocyanate and an isocyanate-reactive material, the reaction product having a Tg of less than −30° C. based on a Differential Scanning calorimetry (2nd Heating) temperature scan from −100° C. to 150° C. using 20° C./min heating and cooling ramps. The isocyanate-terminated reaction product and the linear aliphatic polyisocyanate can be present at a weight ratio of from 0.5 to 2.5.
