Applications

Applications and Uses
Printing Inks
Lupasol WF is an effective adhesion promoter for printing inks for laminated films. It’s particularly suitable for sandwich-printed laminated films with an application rate of 0.5 to 1%. Must only be used with alkali-stable binders and pigments.
Flocculant
Lupasol P is used to flocculate highly charged anionic particles, showing excellent results in precipitating proteins, zeolites and silicates.
Adhesion Promoter in Car Tires
Lupasol WF improves adhesive properties of styrene-butadiene rubber towards tire fibers, particularly effective in systems based on resorcin/formaldehyde, vinylpyridine and polyethylene terephthalate.
Adhesives
Lupasol products (particularly P, PS and HF) can be used as adhesion promoters in combination with various polymers. Application concentration is typically 0.1 – 5% active substance.
Coatings and Paints
Used as primers to improve adhesion. Lupasol P is particularly effective in UV-curing systems. Small concentrations (0.1%) of Lupasol G 20 improve wet adhesion in standard emulsion paints.
Textile Auxiliaries
Lupasol P improves fixation of reactive dyes on cotton and can be used to fix flame retardants. Can be applied during pretreatment or aftertreatment.
Packaging Films
Lupasol P serves as an effective adhesion promoter in multilayer packaging films, improving physical, chemical and mechanical properties while increasing barrier effects.
