| 配制方法： |
To prepare this vehicle heat the coumarone resins and liquid coal tar together to a temperature of 445'F, add the zinc resinate, and hold temperature until it is all melted in. All of the petroleum spirits and 80 gallons of the required Hi-Flash naptha may then be added. The chlorinated rubber can then be dissolved into the remaining Hi-flash naphtha at room temperature. The chlorinated rubber should be blended in with the remainder of the ingredients only after the coumarone-coal tar-resinate mixture has cooled to 140'f or less. To avoid decomposition, the chlorinated rubber should never be heated above 140'F. Although this method is preferred, the vehicle may also be prepared by cold-cutting the indicated ingredients. |
