DANCOLL® 244-21E is a soft, non-crystallizing polyurethane adduct. The low-molecular weight structure of this product was chosen for its application as a ground-coat and primer. DANCOLL® 244-21E is free from aromatic solvents. Application: DANCOLL® 244-21E serves as a raw material component for very high-grade primer solvents which are mainly used for greasy leathers. As to porous substrates with a low inherent strength, the material strength is essentially improved by using DANCOLL® 244-21E as a primer. Due to its soft and elastic films, DANCOLL® 244-21E can be applied as an adherent surface for porous materials, such as leather, paper and textiles. In two-component systems, DANCOLL® 244-21E participates in the cross linking by adding polyisocyanate cross-linking agents. We recommend the addition of approx. 3 to 10 % of our hardeners DANCURE® 246-00 or DANCURE® 246-06. Information provided by Danquinsa GMBH |
