[DO NOT USE] ETONIS® 7622 A (USA)

[DO NOT USE] ETONIS® 7622 A (USA) is a vinyl acetate/ethylene copolymer powder with high ethylene content that makes the polymer soft and elastic and is used in both hot and cold asphalt applications. [DO NOT USE] ETONIS® 7622 A (USA) is a polymer powder with a low glass transition temperature (Tg) that remains flexible down to temperatures below freezing and is suitable for end products with low emissions.


Eigenschaften

Hot asphalt

[DO NOT USE] ETONIS® 7622 A (USA), when used in combination with SBS-type polymers, makes hot asphalt binders easier to process and pump because it reduces the viscosity and generally lowers the processing and application temperatures. Further, [DO NOT USE] ETONIS® 7622 A (USA) helps with faster cooling of a polymer-modified asphalt batch. It significantly improves adhesion to aggregate, improves low temperature flexibility, bleeding and phase segregation. A VAE/SBS modified binder improves adhesion to aggregate and increases the overall toughness and durability. [DO NOT USE] ETONIS® 7622 A (USA) has a plasticizing effect in modified asphalts and improves workability without compromising performance properties.

Cold asphalt

In cold asphalt emulsions, [DO NOT USE] ETONIS® 7622 A (USA) is compatible with both cationic and anionic systems. [DO NOT USE] ETONIS® 7622 A (USA) improves rheology, adhesion, tack, enhances flexural strength, flexibility, drying, abrasion and oil resistance.

Practical benefits

[DO NOT USE] ETONIS® 7622 A (USA)  is a solid polymer, so transport costs are less than for liquid dispersions. Using [DO NOT USE] ETONIS® 7622 A (USA) cuts overall energy costs due to easier processing and lower temperature application.

[DO NOT USE] ETONIS® 7622 A (USA)  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

[DO NOT USE] ETONIS® 7622 A (USA) 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 [DO NOT USE] ETONIS® 7622 A (USA) 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

[DO NOT USE] ETONIS® 7622 A (USA) may be used with both anionic and cationic asphalt emulsions. When using with cold asphalt emulsions, [DO NOT USE] ETONIS® 7622 A (USA) 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 [DO NOT USE] ETONIS® 7622 A (USA) 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 [DO NOT USE] ETONIS® 7622 A (USA) is used in applications other than those mentioned, the choice, processing and use of [DO NOT USE] ETONIS® 7622 A (USA) 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.

Lagerung

Das Produkt ist während der Lagerung vor der Einwirkung von Feuchtigkeit zu schützen. Eine längere Lagerung bei Temperaturen über 30°C, auch in Verbindung mit Druckbelastung, Feuchtigkeit oder Sonneneinstrahlung, kann zur Verblockung führen. Offene Gebinde sollten sorgfältig verschlossen und ebenfalls entsprechend gelagert werden. Daher empfiehlt sich ein Lagerhaus, in dem das Produkt kühl und trocken aufbewahrt werden kann. Lagern Sie das Produkt nicht länger als sechs Monate, beginnend mit dem Eingangsdatum, es sei denn, das Analysezertifikat enthält ein anderes Datum, welches dann Vorrang hätte. Eine Lagerung über den empfohlenen Zeitpunkt hinaus bedeutet nicht, dass das Produkt unbrauchbar geworden ist. Eine Überprüfung der für den vorgesehenen Einsatzzweck erforderlichen Eigenschaften durch den Anwender ist dann jedoch ratsam.
