• Very good wetting effect

• High surface activity

• Improves the adherence of coatings 

Application technique 

Diluting instruction 
HANSA CARE 1050 is soluble in water and all polar solvents.  
Application fields 
HANSA CARE 1050 is suitable as wetting agent for substrates which are difficult to wet. 

Application proposal 
Due to the non ionic character of HANSA CARE 1050 it can be used in combination with mostly all common finishing products. 

Due to its marked surface active properties even polar and non polar surfaces, for example polyethylene, polyvinylchoride or siliconised materials may be easily wetted by aqueous systems. It is possible to reduce the surface tension of many organic media by the addition of HANSA CARE 1050. This will improve the adhesion of polar sizing agents, adhesives or coatings.
