  • Foundry moulds and cores
    Patent number: 4474904
    Abstract: A foundry moulding composition comprising(a) a granular refractory material,(b) from 0.25 to 2.5% based on the weight of the refractory material of an aqueous solution of a potassium alkali phenol-formaldehyde resin, said aqueous solution having a solids content of from 50 to 75% and said resin having a weight average molecular weight (M.sub.wr) of from 700 to 2000, a formaldehyde:phenol molar ratio of from 1.2:1 to 2.6:1 and a potassium hydroxide:phenol molar ratio of from 0.5:1 to 1.2:1;(c) from 0.05 to 3% based on the weight of said aqueous solution, of at least one silane, and(d) from 20 to 110% based on the weight of said aqueous solution of at least one ester active to catalyze curing of said resin.
    Type: Grant
    Filed: October 14, 1982
    Date of Patent: October 2, 1984
    Inventors: Peter H. R. B. Lemon, Jeffrey D. Railton, Derek W. Baker, Vincent J. Coppock
