Defoamer
A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed.
The defoaming agent is resistant to high temperatures, light in color, has good water dispersibility, is not prone to fish eyes and shrinkage cavities, and has no oil slicks or demulsification. It is suitable for all types of coatings and emulsions, water-based resins, and adhesive systems.

Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional Supplement: Together with other iron compounds, ferrous sulphate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: Ferrous sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.

THF is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings, and used in combination. As a reaction solvent, the thickness and brightness of the aluminum layer can be arbitrarily controlled when used in the aluminum electroplating solution. THF itself can be polycondensed (ring-opening and repolymerization initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubbers with abrasion resistance, oil resistance, good low temperature performance and high strength; with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elastic Material.
FH products are Pure nonionic derived the endosperm of guar polysaccharide (Cyamopsos tetragonolobus). The products are unique with ultra-high viscosity with fastest hydration characteristics as shown in Figure 1 below. Also, when added with other drilling components, to seawater, a KCl solution or other aqueous system, the product suspension disperses readily without lumping, even under low-shear conditions generating most of its full viscosity within just a few minutes.
PRODUCT COMPATIBILITY:
FH series of products are compatible with most of the chemicals and auxiliaries used in drilling operations. However, the products are not compatible with Arabic and Crystal gums. Also, in presence of borates they form elastic gel.
PRODUCT APPLICATIONS:
FH series of products are natural, high viscosity, fast hydrating non-Newtonian hydrocolloids with suitable cross linking components in diesel slurries and are versatile for continuous mix applications, where extremely fast hydration and subsequent viscosity development is required. They are excellent viscosifiers, stabilizers, thickeners and suspending agent for use in oil-drilling, workover fluids and several other oilfield applications like hydraulic fracturing, oil well stimulation, mud drilling, oil well capping, flocculent and liquid shoring etc. The product is used as a surfactant; synthetic polymer and deformer ideally suited for all rheological requirements of water based and brine based drilling fluids.

Performance characteristics
1. As a broad-spectrum, long-lasting bactericide to kill many bacteria, fungi and yeasts, the using amount is small.
2. Suitable for use in the medium of the pH value in the range of 2 to 9; free of divalent salt, cross-link no emulsion.
3. Miscible with water; can be added in any production step; easy to use.
4. It has a low toxicity and an appropriate concentration of using, which will lead to no harm completely.
Usage and Cautions
1. In water treatment applications, dilute it into a 1.5% aqueous solution first. Add the solution at a quantity of 80 to 100 ppm for one or two times each week depending on the multiplication of microorganisms like bacteria and algae.
2. Avoid direct eyes' contact with it for a long period. Once the contact happens, rinse eyes with water without delay. No long-term contact with the skin is allowed.
3. Any contact with reducible metals is forbidden during storage, for example, iron and aluminum, so as to avoid decomposition.
4. Not suitable for use in the alkaline medium of pH> 9.0 due to its poor stability. Any combination of this chemical with highly nucleophilic chemicals, like S2- and R-NH2, will lead to declined quality or even complete failure of the product.
Isododecane is an important ingredient in cosmetics. It can be used as an emulsifier for pastes in cosmetic products to help mix water and oil-based ingredients together to achieve a uniform distribution and texture of the product. Since it is colorless, tasteless and odorless, it does not affect the aroma or color of the cosmetic. It is used as a cosmetic solvent to make the product fresh, easy to wipe, and can reduce and prevent the outflow of water from the skin. In addition, due to its stability, isododecane is often used as a solvent for chemical reactions. In analytical chemistry, it is also commonly used as an internal standard to determine the yield and conversion rate of a reaction, and a known concentration of Isododecane can be added to the analytical sample to correct the analytical data and ensure accuracy.
