This product can be diluted with water. It is only partially compatible with glycol ether and alcohol, and the compatibility and storage stability of the diluted solution must be tested.

BI-70 needs to be stored in a sealed container. The recommended storage temperature is 5℃~25℃. The product is sensitive to freezing. Freezing will have an irreversible effect on the product. Long-term high-temperature storage will cause the viscosity to drop, which will cause the precipitation and coagulation of the product.
