Abstract
PURPOSE: A melamine/phenol resin composition which has excellent tracking resistance even in dry process, prepared by adding gypsum to a melamine/phenol resin composition.
CONSTITUTION: A composition comprising a solid melamine resin precondensate, a solid phenol resin precondensate and gypsum. The proportion of gypsum to the solid resins is preferably 5W20pts.wt. of gypsum to 100pts.wt. of the resins. The reason is that the use of gypsum less than 5pts.wt. has little effect on tracking resistance and so is not practicable, whereas the use of gypsum more than 20pts.wt. lowers flexural strength, and can not provide tracking resistance which is better than that obtained by the use of 20pts.wt.
