ETONIS^® 7601 A

ETONIS^® 7601 A is suitable for modifying both hot asphalt binders in combination with SBS-type polymers as well as anionic and cationic cold asphalt emulsions. It is used in waterproofing, roofing, hot mix paving, tack coat, chip seal, fog seal, scrub seal, microsurfacing and sealers, and other asphalt applications.

Processing

Hot asphalt

ETONIS^® 7601 A may be added in powder form either to the hot asphalt binder at any time in the process with either paddle or high shear mixing. Mixing and pumping the hot asphalt binder causes the polymer powder to redisperse rapidly and blend with both the SBS and asphalt binder. Typically 25 wt. % of SBS is replaced with ETONIS^® 7601 A to enhance hot asphalt binders. The amounts used in special applications for higher ductility and elongation may be considerably higher. The exact amount will depend on the requirements profile.

Cold asphalt

ETONIS^® 7601 A may be used with both anionic and cationic asphalt emulsions. When using with cold asphalt emulsions, ETONIS^® 7601 A may first be mixed with gauging water and then added to the asphalt emulsion or may be added as a powder directly to the asphalt emulsion. Protracted stirring of the polymer/water mixture is apt to cause individual components to settle out, but brief mixing will produce a homogenous mixture again. The amount of ETONIS^® 7601 A needed to modify cold asphalt emulsions ranges from 2.5 - 5.0 % v/v relative to the asphalt emulsion. The amounts used in special applications for improved ductility, flexibility and elongation may be considerably higher. The exact amount will depend on the requirements profile.

If ETONIS^® 7601 A is used in applications other than those mentioned, the choice, processing and use of ETONIS^® 7601 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.
