Claim 1

A COMPOSITION CAPABLE OF HARDENING RAPIDLY IN THE COLD TO YIELD CHEMICALLY RESISTANT MASSES, COMPRISING AN INERT FILLER, A HARDENING AGENT, A STILL LIQUID RESIN OBTAINED BY CONDENSING FORMALDEHYDE AND PHENOL IN THE MOLECULAR PROPORTION RANGING FROM ABOUT 1:1 TO ABOUT 1.8:1 IN AN ALKALINE MEDIUM; A COMPOUND SELECTED FROM THE GROUP CONSISTING OF DIETHYL SULFATE, DIPROPYL SULFATE, DIBENZYL SULFATE, TRIETHYL PHOSPHATE, 1,3DICHLOROPROPANOL, EPICHLORHYDRIN, DICHLORHYDRIN, ETHYLENE CHLOROHYDRIN, SAID COMPOUND BEING PRESENT IN AN AMOUNT RANGING FROM ABOUT 5 PER CENT. TO ABOUT 25 PER CENT., CALCULATED UPON THE AMOUNT OF THE RESIN USED; AND FURFUROL IN AN AMOUNT RANGING FROM ABOUT 10 PER CENT. TO ABOUT 90 PER CENT., CALCULATED UPON THE AMOUNT OF THE RESIN USED.
