摘要：
The invention relates to a binder composition comprising a low molecular weight poly (orthomethylolated) phenolic compound which is combined with a phenol formaldehyde novolac resin and cured in the presence of alkali and an organic ester. Low and high density aggregates can be added to the binder to produce foundry or refractory articles. The binder can also be applied, with or without aggregate, to paper, fabrics, or concrete.
