Lupasol® G 20


Because of their high charge density, Lupasol products adsorb strongly on negatively charged surfaces such as cellulose, polyester, polyolefins, polyamides and metals. They are therefore used as adhesion promoters for bonding different materials. The usual application rate for these applications is very low, in the 50 – 150 mg/m2 range. In addition, owing to the large number of peripheral amino groups, Lupasols can act as physical or chemical crosslinking agents in coatings, paints and adhesives.


Lupasol products are clear to slightly turbid*, colorless to yellowish liquids. Their viscosity depends on the molecular weight, concentration and degree of branching.
