1. Water repellent treatment of plaster
BLUESIL WR 68 is added to the water to be mixed with the plaster preparation. Good water repellent properties are obtained by adding 0.2 to 0.5 % BLUESIL WR 68 relative to the plaster powder. The quantity of water repellent varies according to the grade of plaster and the plaster-water mixing ratio. Adding BLUESIL WR 68 to the plaster enables water absorption to be limited to values less than those set in current European standards.

2. Treating fillers
In this case BLUESIL WR 68 is used on its own, or for example with 3 % of glycol tetraoctylene titanate. Polymerisation takes place at room temperature. It may be accelerated by heating for a few minutes at .

Comments: Do not bring near potash or caustic soda or any other alkaline compound. There is a risk of a violent release of highly inflammable products.
Similarly, do not use in the presence of alcohols (or solvents containing a significant proportion of them) or other components containing reactive hydrogen atoms (SH, OH…) since hydrogen release may again occur.

Avoid discharge into drains, water courses or onto the ground. Store in original tightly closed container. equipped with a degassing device. Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures.请查阅这个产品的物质安全数据表欧盟《报废车辆指令》;全球有机纺织品认证标准;国际环保纺织协会标准;欧盟《电气、电子设备中限制使用某些有害物质指令》
