Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
IN A DUAL-PURPOSE CONCRETE-CURE AND ANTISPALLING COMPOSITION OF THE AQUEOUS EMULSION TYPE WHICH NORMALLY CONTAINS A BOILED LINSEED OIL (LSO) OIL PHASE, EMULSIFIERS, AND STABILIZERS, AN IMPROVEMENT WHICH COMPRISES AN AQUEOUS EMULSION IN WHICH THE RATIO OF OIL PHASE TO WATER PHASE IS FROM 55/45 TO 45/55 I VOLUME/VOLUME, AND SAID OIL PHASE CONTAINS FROM 50 TO 90 VOLUME PERCENT BOILED LSO AND FROM 10 TO 50 VOLUME PERCENT OF A COMPOSITION SELECTED FROM THE GROUP CONSISTING OF HEAT-BODIED LSO, HAVING A GARDENER-HOLDT VISCOSITY OF FROM Z-2 TO M-37, AN ACID NUMBER FROM 3 TO 22, A SAPONIFICATION NUNUMBER FROM 187 TO 194, AND AN IODINE NUMBER FROM 115 TO 175, RAW TUNG OIL HAVING A BROOKFIELD VISCOSITY OF 950 CENTIPOISES, AND MIXTURES OF THE SAME.
