Therefore wax additives are well suitable for surface protection. Depending on the wax base they improve: e.g. scratch resistance, soft feel effect, scrub resistance etc. * * * * * * * * * * * * * * * * * The easiest way to use T1890 is as a blend. The customer can continue using his existing formulation (i.e. resin and hardener he is familiar with). The T1890 replaces N-75 or N-33xx partially. Very important: catalyst amount must be increased. * 用于溶剂型体系的蜡助剂 130 110 90 70 50 150 Ceramat 248 Ceraflour 996/ 990/ 991 Ceraflour 995 Ceraflour 993/994 Ceraflour 950 Ceracol 600 Ceracol 601 Ceramat 237 Ceramat 250 Cerafak 116 Cerafak 127 Ceramat 241/ Cerafak 151 Ceraflour 970 Ceraflour 980 融 点 °C 防 滑 性 抗 回 黏 疏 水 性 抗 机 械 性 滑 爽 低
