PURPOSE:To provide the titled compsn. which can be cured at an industrially useful rate even in a relatively low temp. region, by blending a phenolic resin with hexamethylenetetramine and thioureas. CONSTITUTION:100pts.wt. phenolic resin is blended with 5-20pts.wt. hexamethylenetetramine, 1-15pts.wt. at least one thiourea (e.g., N,N- diphenylthiourea) and optionally a filler, a reinforcing agent, a lubricant, a plasticizer, a colorant, a curing accelerator, etc. In this way, a phenolic resin compsn. which can be cured at an industrially useful rate in the temp. region of 130 deg.C or higher can be obtd.
