摘要： This invention generally provides blocked isocyanate compositions and more specially blocked isocyanate compositions useful in aminoplastic resins, phenoplastic resins or latex resins for composite wood products, wherein the blocked isocyanate composition is obtained by adding alkylene carbonate to a blocked isocyanate (A), wherein the blocked isocyanate (A) is obtained by reacting a secondary amine (a1) with a reaction product (a2) of a polyfunctional isocyanate and a monofunctional hydroxyl containing compound, wherein the monofunctional hydroxyl containing compound is a polyethylene oxide polymer with terminal hydroxyl group, polyoxyethylene-polyoxypropylene monols or a mixture thereof, wherein the portion of blocked isocyanate (A) by weight percentage of the blocked isocyanate composition is between 50 and 90, preferably between 60 and 80. The compositions are stable at room temperature when mixed with active hydrogen containing compounds. The composition has low visicosity and after de-block has the potential to reduce free formaldehyde levels in formaldehyde containing resins.
