Higher gloss 更高光澤 ? Lower haze 更低霧影 ? Good levelling 流平性更好 ? Defoaming or no foam stabilization 消泡或不穩(wěn)泡 Poor performance: 性能差 (too inpatible) （太不相容） ? Glossreduction 光澤降低 ? Haziness 霧影 ? White spotting 白點 ? Sticky surface 粘的表面 ? Cratering tendency and orange peel effect 縮孔傾向和橘皮 ? Foamstabilization 穩(wěn)泡 ?
