ETONIS® 7245 A

ETONIS® 7245 A is a poly(vinyl alcohol) stabilized vinyl acetate-ethylene copolymer dispersion with a glass transition temperature (Tg) of +23 °C. and is used in asphalt emulsion-based applications. ETONIS® 7245 A imparts excellent adhesion, abrasion resistance, tensile strength, film flexibility, and faster drying time.


ETONIS® 7245 A can be compounded with asphalt emulsion and is combinable with common additives such as emulsifier, defoamer, thickeners and fillers. In asphalt emulsion, ETONIS® 7245 A is compatible with both cationic and anionic systems. ETONIS® 7245 A improves rheology, softening point, elastic recovery, torsional recovery and tensile strength in residual asphalt. It provides excellent adhesion, abrasion resistance, and fuel resistance in surface treatment applications.

ETONIS® 7245 A is suitable for modifying both anionic and cationic asphalt emulsions where rapid setting, good machining, and easy clean-up properties are required. It is used in waterproofing, roofing, tack coat, chip seal, fog seal, scrub seal, micro surfacing and sealers, and other cold asphalt applications.

If ETONIS® 7245 A is used in applications other than those mentioned, the choice, processing and use of ETONIS® 7245 A is the sole responsibility of the purchaser. All legal and other regulations must be complied with. Slight discoloration may occur without impairing the product's functionality.

ETONIS® 7245 A may be used with both anionic and cationic asphalt emulsions. ETONIS® 7245 A can be incorporated into asphalt emulsion through addition to the soap solution (batch process) or via co-milling (continuous process). It may also be added directly to the asphalt emulsion with minimal stirring. The amount of ETONIS® 7245 A needed to modify cold asphalt emulsions ranges from 1.0 - 5. % v/v relative to the asphalt emulsion. The amounts used in special applications for higher ductility, flexibility and elongation may be considerably higher. The exact amount will depend on the requirements profile.
