While "G-4" can be impregnated into rope and cordage from solvent solution, it is usually preferred to add the "G-4" to the cordage oil used in the manufacturing process. "G-4" may not be soluble in the cordage oil. In some cases, solutions can be prepared by. adding the "G-4" to the oil as a 20% solution in dipropylene glycol or similar solvents; the use of wool grease in the oil increases the solubility of the "G-4." Also, "G-4" may be satisfactorily dispersed in the cordage oil if continuous agitation of the oil can be accomplished.
In Government Specification MIL-R-16070 (SHIPS), a combination of copper naphthenate and "G-4" is prescribed for the treatment of rope; it is required that 0.125-0.025% copper calculated as metal and 0.125-0.025% "G-4" based on the weight of the rope are deposited in the material. If we assume that the pickup of cordage oil by the rope fibers is 12%, the cordage oil must contain 1.0% "G-4". This is equivalent to adding 5 lb.
of the 20% solution of "G-4" in dipropylene |
