Application

Tephamine^TM E85 Emulsifier for cationic slow-set bitumen emulsions such as prime coat, dense grade cold mix and cold recycling, grave emulsion mixes. It is also can be adopted for slurry seal and application when adequate mix time is required for those most difficult aggregate in the high temperature. Tephamine^TM E85 Emulsifier can provide long workability for the cold recycling application when certain period of stockpile is required.

Tephamine^TM E85 is slightly dispersible in water. Emulsifier solutions can be prepared by addition of hydrochloric acid to the dispersed emulsifier. Tephamine^TM E85 also acts as breaking retarder when extra mix time is required.

Tephamine^TM C103 Emulsifier for cationic slow-set bitumen emulsions for spray seal applications such as prime coat and tack coat. Tephamine^TM C103 can also be used together with other emulsifiers, such as Tephamine^TM C408, to enhance mixing stability when used in medium setting emulsions or coarse aggregate mixes or for penetration macadam.
Tephamine^TM C103 is slightly dispersible in water. Tephamine^TM C103 need not be neutralized if used alone, but if a lower pH is required it is recommended to use hydrochloric acid. Emulsifier solutions can be prepared by addition of hydrochloric acid to the dispersed emulsifier.

Tephamine^TM C471 Emulsifier for cationic quick-set bitumen emulsions for slurry seal and Microsurfacing applications. It is particularly advantageous in the production of slurry seal and Microsurfacing emulsions. The product is especially suitable for reactive aggregate when enough mix time is required.
Tephamine^TM C471 is slightly dispersible in water. Emulsifier solutions can be prepared by addition of hydrochloric acid to the dispersed emulsifier.

Application

Tephamine^TM C408 Emulsifier for cationic medium-set bitumen emulsions. Cold Mixes based on emulsions containing Tephamine^TM C408 show good water resistance.
Tephamine^TM C408 gives a low viscosity emulsion even with bitumen that tends to build high viscosity emulsions. For the best performance of Tephamine^TM C408 it is recommended that calcium chloride is included in the emulsion formulation at a level of 0.05-0.15%.
Tephamine^TM C408 is dissolved in water by neutralization with hydrochloric acid. A suitable way to manufacture water-phase solutions is to first fill a container with the desired amount of water, heated to 60-70ºC. Add hydrochloric acid corresponding to approx. 50% of the experience dosage (from last production), then add the Tephamine^TM C408 slowly under stirring to give a uniform dispersion. Add the rest of the acid to give the desired PH.

Tephamine^TM EM22 is a liquid emulsifier for rapid and medium setting cationic emulsions. It offers the advantages of good liquidity, economic use level and excellent emulsion quality.
For the best performance of Tephamine^TM EM22 it is strongly recommended that calcium chloride is included in the emulsion recipe at a level of 0.1-0.2%. Hydrochloric acid may be used to adjust the pH of the water phase.

Application

Tephamine^TM A05 Emulsifier for anionic bitumen emulsions for spray seal applications such as prime coat and tack coat and dust control. It is also widely adopted for waterproofing application. Tephamine^TM A05 offers the advantages of excellent emulsion quality with economy dosage level (when produce anionic rapid setting emulsion). Tephamine^TM A05 are reactive with Ca+ and Mg+ and it is recommended to avoid use water with high Ca+ and Mg+ content to prepare the water phase.

Tephamine^TM A05 is slightly dispersible in water. Emulsifier solutions can be prepared by addition of Sodium hydroxide to the dispersed emulsifier.

Tephamine^TM E6 Bitumen emulsifier is designed for producing both cationic and anionic slow-set bitumen emulsions with amphoteric type of surfactant. It has good water solubility with easy handling. Emulsion produced with Tephamine^TM E6 are suitable for applications such as prime coat, dense grade cold mix and cold recycling, grave emulsion mixes. It is also can be adopted for slurry seal and application when adequate mix time is required for those most difficult aggregate in the high temperature.

Application

Tephabond^® AP-1 is a liquid additive, specially designed for hot-mixed
Bitumen applications where good heat stability is required.
Tephabond^® AP-1 may be stored in hot bitumen for up to 5 days at temperatures up to 170ºC without significant loss of activity.

Application

Tephabond^®AP-7 is a multipurpose adhesion agent for use in bitumen, road oils and cut-back binders with the advantages of good heat stability, liquidity and low volatility. The stability of Tephabond^® AP-7 in hot bitumen depends however on the acid value and the temperature of the bitumen.

The dosage of Tephabond^® AP-7 depends on the type of bitumen and aggregate used.
For hot mix application, between 0.2- 0.5% is added to the binder;
For Soft binder, between 0.5%-1.0% is added to the binder.
