METHOD OF DECREASING WAX IMPREGNATION TIME BY POROUS PAPER PRODUCTS |
| 摘要 |
The rate at which a porous paper product absorbs molten paraffin waxes with a melting point less than 136 DEG F. (AMP) is substantially increased by the addition of a small amount of an ester or mixture of esters of a fatty acid and a polyhydric alcohol to the wax before application.
