5. Method of use
WF-8230 defoamer has excellent defoaming and anti-foaming properties. According to the different use system, the amount of defoamer can be 10~1000ppm, appropriate amount of defoamer can effectively prevent and eliminate foam, do not use too much, the best amount of addition is determined by the customer according to the specific situation of the test. WF-8230 defoamer products can be used directly or after dilution. If it can be fully stirred and dispersed in the foaming system, it can be added directly without dilution. If dilution is required, use thickened water. Direct dilution of the product with water is not desirable, prone to delamination demulsification and other phenomena, thus affecting the quality of the product. The Company shall not be liable for any consequences arising from direct dilution with water or other improper processing or use of the product
6.Storage and Packing
WF-8230 defoamer is packaged in plastic drums of 25kg, 50kg or 200kg. If there are special requirements can be customized through consultation.
WF-8230 defoaming agent is suitable for 10~30℃ storage, do not place near heat source or sunlight exposure. Do not add to this product
Acid, base, salt, etc. Keep containers sealed when not in use to prevent contamination by harmful bacteria. If there is a long time to stratify, to stir all
Evenly, generally does not affect the use effect. This product will freeze below 0℃, if freezing occurs, use after melting, you need to stir.
According to the general chemical storage method. Ensure sealing after use to avoid deterioration
The shelf life is 12 months from the date of production at the recommended storage temperature and in unopened package
