2.产品特点及用途PW-18、PW-28，按树脂之0.4-3%加入，可加速氨基树脂与含羟基树脂的交联，起到降低烘烤温度与缩短烘烤时间。选择不同类型的酸催化剂，可以调节涂层的耐溶剂性、柔韧性、附着力及硬度，使涂料达到不同要求的理想效果。PW-18、PW-28产品，广泛应用于彩钢涂料、印铁涂料、汽车烘烤等烘烤型工业涂料，也可以用在生产聚酯树脂中的催化剂原料，及其它领域中。

Characteristics and Usage

PW-18 or PW-28 is added by 0.4-3% based on the resin.It accelerates crosslinking rate between amino resin and hydroxyl resin and reduce baking temperature and period.It canimprove solvent resistance, flecibility,adhesion and hardness of the coating to select proper type of acide catalyst,which can achieve the desire effect of differrnt reuirement.PW-18 and PW-28 are widely used for the baking coating as well as for catalyst in the production of polyester resin.

3.使用方式PW-18、PW-28酸催化剂，在使用前，一般用醇类、醚类等溶剂，稀释成含量为10-50%的极性溶剂使用。Application

Prior to application,the acid catalyst,PW-18 or PW-28,can generally by diluted with alcohol or ether solvents to 10-50% so as to be used as polar solvent.
