Process

Notice

1. The containers must be kept tightly sealed, otherwise evaporization of water leads to the formation of a film which is not redispersible.

2. Temperature above 40℃ must be avoided.

3. The product is sensitive to frost, and must therefore not be stored at temperature below 5℃. It’s not possible to thaw the product after freezing.

4. WPU-70-17GLW can be stored at 5-40℃ for 6 months in original sealed containers.

Packing

20kg/pail or 200kg/drum.
