PURPOSE: To produce efficiently various kinds of amino resin molding materials without variation in quality, by using in combination two kinds of amino resins contg. a specified amount of formaldehyde added thereto.
CONSTITUTION: An amino resin (base resin) (A) obtd. by adding 1.1W1.5mol of formaldehyde per mol of an amino compd. such as urea, melamine or guanamine, and an amino resin (auxiliary resin) (B) obtd. by adding 1.6W8mol of formaldehyde per mol of said amino compd., are prepared. Then the resins A and B are blended in a required ratio according to the purpose of use. Further, additives such as a hardener, a filler, a lubricant, a colorant, etc. are added thereto to form easily resin molding materials which meet required applications.
