Lupasol G20 is a 50% aqueous solution of a low molecular weight, branched polyethyleneimine (PEI) polymer. This highly cationic polymer acts as an excellent adhesion promoter, dispersing agent, and flocculant. It is miscible with water and polar solvents, making it versatile for formulations. Key applications include improving wet adhesion in paints and coatings, especially in high humidity environments like bathrooms and kitchens, and as an additive in adhesives due to its crosslinking capabilities
