    • A powder coating compositions incorporates a wax in post-blended form, the composition incorporating the wax and the same composition without the wax being separated, preferably widely separated, in a triboelectric reference series indicative of the extent to which powder coating compositions may be distinguishable from one another when electrically charged. The powder coating compositions incorporating a wax in post-blended form is especially suitable for coating articles having recessed portions. A quantitative basis is given for determining separation in the triboelectric reference series, and preferred minimum separation criteria are given. The effects obtainable using post-blended wax may be enhanced by the use, as further post-blended additives, of a combination of aluminium oxide and aluminium hydroxide.

    • A method of preventing re-swelling of a compressed wooden blank, includes the steps of: a) providing a blank of compressed wood; b) exposing the blank to a reduced gas pressure of at most 0.5 atm; c) submerging the blank in a volume-stabilising composition containing a hydrophobic base component and an additive which is compatible with the hydrophobic base component and which includes one or more hydrophilic groups chosen from carboxyl-, hydroxy- and amino groups; d) exposing the blank to a higher pressure than in step b) over a predetermined period of time while keeping the blank submerged in the volume-stabilising composition; and e) removing the blank from the composition. Steps b) and step c) are carried out simultaneously.
    • 防止压缩木质坯料再膨胀的方法包括以下步骤:a)提供压缩木材的坯料; b)将坯料暴露于至少0.5atm的减压气压; c)将空白物浸入含有疏水性碱性成分和与疏水性碱性成分相容的添加剂的体积稳定化组合物中,该添加剂包括一个或多个选自羧基,羟基和氨基的亲水基团; d)将坯料暴露在比步骤b)更高的压力下,同时保持浸没在体积稳定组合物中的预定时间; 和e)从组合物中除去空白。 步骤b)和步骤c)同时进行。
