CAS Number: Not specified (proprietary formulation; emulsion of montan wax or related synthetic wax)
Product Status: Discontinued (per manufacturer information)
Synonyms:
Michelman Licomer W 485; Licomer W 485; Cationic montan emulsion; Montan wax emulsion (cationic); High gloss emulsion
Chemical Identity and Properties:
Licomer W 485 was a specialized cationic emulsion of montan wax or a related synthetic wax, manufactured by Michelman. Montan wax is a hard, high-melting-point wax derived from lignite (brown coal) or produced synthetically. The "cationic" designation indicates that the emulsion droplets carry a positive charge, which provides specific advantages in certain applications:
Cationic charge: Promotes adhesion to negatively charged substrates (many natural and synthetic surfaces)
Emulsion form: Water-based, easy to incorporate into aqueous formulations
Montan wax base: Provides hardness, high gloss, and water resistance
Physical Properties (Typical for Montan Emulsions):
Appearance: Opaque white to off-white emulsion
pH: Typically 4–6 (cationic emulsions are stable in acidic to neutral pH)
Specific Gravity: Approximately 0.98–1.02
Volatiles: Primarily water
Viscosity (Brookfield): Low to medium viscosity (typical for water-based emulsions)
Particle Size: Fine particle size for high gloss and stability
Ionic Character: Cationic (positively charged)
Applications (per manufacturer):
Licomer W 485 was specifically formulated for use in floor crystallizers, where it served to:
Improve gloss: Provided high-gloss finish on floor surfaces
Enhance performance: Improved durability and appearance of floor finishes
Surface protection: Contributed to protective coating properties
Additional applications typical of cationic montan emulsions include:
Paper coatings: Provides water resistance, gloss, and surface properties
Textile finishing: Adds softness, lubricity, and water repellency
Leather finishing: Enhances surface properties and durability
Polishes: Floor, furniture, and automotive polishes
Release coatings: Mold release and anti-blocking applications
Discontinued Status:
According to manufacturer data (MatWeb), Licomer W 485 is a discontinued product and is no longer part of Michelman's standard product line. While these materials may sometimes be available through distribution inventory or special order, users are encouraged to contact Michelman directly for:
Current replacement products with similar functionality

Advantages of Cationic Montan Emulsions:
Substrate adhesion: Excellent adhesion to negatively charged surfaces (glass, metals, many plastics, natural fibers)
Compatibility: Compatible with cationic and nonionic formulations
Water resistance: Provides hydrophobic barrier properties
High gloss: Produces glossy, durable films
Environmental profile: Water-based; low VOC
Storage and Handling:
Store in sealed containers to prevent water evaporation and skin formation
Protect from freezing (emulsions may be freeze-sensitive)
Store at temperatures between 5–35 °C
Shelf life: Typically 6–12 months for emulsions
Avoid contamination with anionic surfactants (may cause coagulation)
