	FAQ's QUESTION: What is Tall Oil Pitch (T.O.P.)? ANSWER: Crude Tall Oil (CTO) is a product of the sulfate pulp and paper process. CTO is processed in distillation columns to separate out tall oil fatty acids and rosin acids. The first step in this distillation process is de-pitching in which the heavy dark bottom fraction is removed.  This fraction is called tall oil pitch. QUESTION: Is Tall Oil Pitch part of the Lignosulphonate family of products? ANSWER: No. Lignosulfonates are produced and extracted from the sulfite pulp and paper process. They are a water-soluble waste stream. QUESTION: Why is the electrical charge of the emulsion important? ANSWER: The emulsion works by drawing the tall oil pitch to the aggregate. The wetting characteristics of the emulsion need to be matched to the aggregate to which we are applying.  Different aggregates have different chemistry which must be matched up with the appropriate emulsion chemistry. QUESTION: What are emulsions and how are they made? ANSWER: Emulsions are a blend of immiscible materials such as; oil and water. Tall Oil Pitch in its raw state is extremely viscous at ambient temperature and completely insoluble in water. By emulsifying the Tall Oil Pitch in water we generate a stable liquid which can then be stored, transported, pumped and applied at ambient temperatures. The pitch particles are sized and concentrated to the desired percentage of pitch solids required and then evenly disbursed in the total fluids generating an emulsion. QUESTION: Are there any negative enviromental impacts if I use EnsSolutions' T.O.P. emulstions? ANSWER: The EnsSolutions products have no negative environmental impacts. Extensive testing has been completed based on the most recent Ontario Ministry of Environment (M.O.E) Guidelines. The testing included but was not limited to: • Daphnia Magna, Fathead Minnow and Trout LC50 Toxicity Test • Dioxins, Furans • Full metal scan A summary of these lab testing results are available on request. QUESTION: How long will the product last once applied? ANSWER: The longevity of the product once applied is dependent on the application chemistry, how the product is applied and the number of coats. EnsSolutions has the ability to adjust the emulsion chemistry and physical characteristics to meet a variety of applications. Typically, undisturbed material stockpiles and mine tailing fields can be sealed for a few months or in access of two years if required. Landfills and construction sites can be sealed daily, weekly or as required. QUESTION: Does EnsSolutions produce more than one type of emulsions? Why? ANSWER: Yes. Entac products can be custom manufactured to meet a variety of unique performance requirements. The application specifications dictate the emulsion performance characteristics such as: • Coating characteristics • Particle size distribution • Curing times • Wetting characteristics • Electrical charge QUESTION: Does EnsSolutions supply technical support in the field? ANSWER: Yes. EnsSolutions' technical support team is well trained to offer a wide range of field support. QUESTION: Can I (The customer) apply the emulsion, or does EnsSolutions have to apply it for me? ANSWER: Yes. We have many customers that apply to their own sites for various applications. EnsSolutions will also arrange for a local applicator to apply the product, if possible, or send one of our application crews to apply the product for you. QUESTION: How is the emulsion shipped? ANSWER: The most common shipping methods are: • Truck bulk tanker • Rail car • Totes (275 gallons) • 5 gallon containers. QUESTION: Does Entac ship product internationally? ANSWER: Yes.
