CBAA FLEX RR-2C-E is a special cationic asphaltic emulsion, modified by elastomeric polymers, which has excellent behavior and durability in the face of the effects of climate and the demands of heavy traffic.

Its formulation with aminated emulsifiers, with fast rupture characteristics, provides fast cohesion of the asphalt/polymer film, through a predominant chemical phenomenon in contact with the aggregate, and the following benefits:

• High power of internal cohesion;
• Satisfactory adhesion with different types of aggregates, acid or alkaline in nature;
• Flexibility;
• Resistance to aging and exudation in the face of large temperature variations;
• Elastic properties when compared to the plastic behavior of binders.

CBAA FLEX RR-2C-E It is used specifically in paving services by spreading and inverted (or direct) penetration of the asphalt binder in surface treatments (in its various modalities), bonding paint, diluted sealing layer bath, anti-dust treatment, bituminous macadam, and for the implantation or resurfacing floors.

In surface treatments, CBAA FLEX RR-2C-E in high viscosity must be heated to a maximum temperature of 70ºC to obtain the appropriate viscosity for spreading through the spreading bar. The rupture of CBAA FLEX RR-2C-E, with a fast characteristic, presents cohesion / fixation of the binder to the aggregates within 2 hours of its application (in the sun), under adequate working conditions. Under humid conditions, the emulsion may bleed.

We recommend consulting our Technical Department for technical guidance regarding the use and application of the CBAA FLEX RR-2C-E.

In case of storage for long periods, it is recommended to circulate the product once every two weeks. Avoid successive recirculation and pumping to prevent a decrease in viscosity and rupture due to entrained air. We do not recommend storage for more than 21 days. It is recommended that the place of storage and storage be properly sealed, to avoid the occurrence of sedimentation and partial rupture.

In diluted painting services, clean water must be used, free of contamination by suspended solids or reactive elements, which may cause premature rupture in the act of dilution or during circulation to homogenize the mixture.

CBAA FLEX RR-2C-E is manufactured in accordance with ANP Resolution No. 897, of 11/18/2022 and DNIT 128/2010 – EM:

CBAA FLEX RR-2C-E it is supplied in bulk, Liquid (tons) in tank cars.

During handling, use PPE (Personal Protective Equipment). In the event of an accident, consult the Safety Data Sheet for Chemical Products (FISPQ – No. CBAA.002).

It is not recommended to carry out paving services using the CBAA FLEX RR-2C-E, at temperatures below 10°C.

Do not store the emulsion diluted with water (binding paint) for a prolonged period, as premature rupture may occur inside the storage tank.

Do not store the asphaltic emulsion after the heating process or successive heating processes, as this could lead to destabilization of the emulsion state and premature rupture of the product.

Do not use polluted aggregates (stone dust, clay) in services using this product.

CBAA FLEX RR-2C-E is classified by the UN (3082), as a substance of risk 9 and subclass N.E (liquid substances that present a risk to the environment).

As for the arrival of the product at the work site, collect the sample for the reception/quality tests. Do not heat the product before the sampling procedure.

In order to adjust the viscosity conditions for spreading, the temperature of the emulsion should be around 65ºC., maximum 70ºC (temperature obtained in the spreading cart).

Contact with the cold product does not cause irritation to the skin, causing burning in the eye when hit. Cold product in contact with the skin will be removed with soap and water. Asphalt residue can be removed with vegetable or mineral oil.

In paving services with diluted paints, clean water must be used, free of contamination by solids in suspension or negative elements, which may cause breakage when diluting the emulsion or during circulation to homogenize the mixture.

The product can be kept in deposits (bulk), duly sealed. It is not recommended to store the product for a period longer than 21 days.

CBAA FLEX RR-2C-E is a medium to high viscosity product. When at rest for a long period of storage, sedimentation of asphalt globules occurs on the lower surface and emergence of the chemical aqueous phase that composes the emulsion, requiring circulation to homogenize the same for its application or the occurrence of partial rupture of the emulsion state .
