发明名称 Coated abrasive and its manufacturing method.
摘要 <p>A coated abrasive product comprising a backing, a first adhesive layer formed on the backing, a layer of abrasive grains formed on the first adhesive layer, and a second adhesive layer covering the layer of abrasive grains, wherein the second adhesive layer is formed from a composition comprising a water soluble resol phenolic resin having a weight-average molecular weight of from 1,400 to 3,500 and an organic solvent having a boiling point of 110 to 175 DEG C, and a process for producing the same. The present invention remarkably shortens a drying time of the second adhesive used in the production of the coated abrasive product of the present invention and improves productivity. &lt;IMAGE&gt;</p>
