heated on to a glass plate shamrock type s 394 n1 wax u2014 mixed with ethanol and sprayed on to a glass plate shamrock type s 394 n1 wax u2014 mixed with ethanol and sprayed and heated on to a glass plate from the observations it was evident that the wax powder was not dissolved in the ethanol it was clear that the wax particles were intact in all the specimens where the various wax powders were mixed with ethanol likewise it seems to be evident that after the heat treatment the wax particles were converted into a transparent homogeneous permanent very stable heat and chemical resistant sheet a gel coated grp plate approx 100 u00d7 400 mm was treated on 50 of one side the wax mix 10 g of davosi polyethylene wax powder in 1000 g of ethanol 96 was applied by airless spray gun on to the steel plates and dried for 3 hours then the surface of the test specimen were heated by a ripack 2000 gas heated gun until the white wax powder was melting and become transparent settled for 12 hours at 20 degrees c at 65 relative humidity the test specimen was submerged into seawater in the leisure boat.
