High performance one-component urethane compositions with excellent weathering properties and method for making and using same. |
摘要 |
<p>A storage stable one-component air curable urethane coating composition having improved color, abrasion resistance and weather resistance comprising at least twenty percent by weight of resin solids of a compound comprising at least one oxazolidine ring chemically combined from the nitrogen atom of the ring through an alkylene-urethane linking group to a tetramethylxylylenediisocyanate prepolymer radical. The invention also comprises the method for preparing the compound and composition and a method for coating a surface by applying the composition of the invention to the surface and exposing the applied composition to air having a relative humidity of at least 10% and includes an article coated with the cured composition.</p> |
