Extend durability by chemical fixation of unsaturated waxes as wood surface finishes

Abstract

Materials and methods: Pinus radiata replicate wafers 110 × 75 × 5 mm were surface painted first with penetrating water solutions of 10%, 5%, and 2.5% CrO 3 followed after 16 hours by a surface penetrating 5% benzene solution of oxidised solid C44 wax, containing an unsaturated C C double bond every 44 carbon atoms, of 44 carbon atoms average chain length and melting point of 105 °C. Replicate specimens were also surface treated with 5% benzene solutions of the same wax, without any CrO 3 pre-addition, but to which were added 2% Methyl Ethyl Ketone peroxide/cobalt nalShthenate as a radical initiator couple. Water wetting angles were measured for all surfaces before and after 41 days exposure to a weatherometer test comprised of superheated steam and ultra violet light cycles. Results obtained are shown in the Table.
