Hardeners

H – 641 APPLICATIONS: Hardener 641 offers outstanding features such as solvent free or high solids systems, cures completely even in presence of moisture and at low ambient temperatures, non critical mixing ratio, adequate adhesion on poorly prepared surfaces and even on plastics, high water and chemical resistance. Hardener 641 is recommended in combination with epoxy resin, L 450 XX for heavy duty maintenance coatings, anti-corrosive coatings, especially for marine coatings. It offers superior chemical resistance and adequate flexibility in above applications. Further it offers very good handling characteristics, fast cure rates and safer handling properties. It also finds further application in masonry coatings, tank and pipe coatings, concrete repair coatings and in certain adhesive applications H – 340 & H-350 APPLICATIONS: Hardener 340 and Hardener 350 is very useful for formulating coatings for tank linings, coatings and linings for concrete and metal pipes, chemical resistant flooring, concrete structural finishes, marine coatings and under water coatings. Hardener 340 and Hardener 350 based coatings gives excellent resistance to organic acids and bases, good mechanical properties, outstanding resistance to abrasion. It cures completely even under water, at low temperature without blushing or exudation. Proper combination of Hardener 340 & Hardener 350 should be selected so as to get desired pot life and cure rate. H-640 APPLICATIONS: Hardener 640 offers outstanding features such as solvent free or high solids systems, cures completely even in presence of moisture and at low ambient temperatures, non critical mixing ratio, adequate adhesion on poorly prepared surfaces and even on plastics, high water and chemical resistance. Hardener 640 finds application in
