Procedure

12 parts by weight of aqueous phosphoric acid (85%) is mixed with 60 parts by weight of aqueous formaldehyde (37%), then 16 parts by weight of urea powder is rapidly added and mixed thereby producing a urea-formaldehyde-phosphate white pre-polymer emulsion. After 10 days the pre-polymer was heated to 50-70 degree C. until the solution became clear, then the resin was poured into a mold and it solidified into a clear solid resin.
