POLCO® 223 can be applied under very low ambient temperature conditions (-40F / -40ºC), in high humidity and in the presence of moisture without affecting the final properties of the material. Proper adhesion relies upon substrate dryness, preparation and compatibility.
 
    
 
POLCO® 223 performs well as a corrosion-resistant coating for concrete and steel applications with extreme exposure to acids, bases, salts and other corrosives.
