Phenalkamine Epoxy Hardeners

Ark Golden has gained an expertise in the production of Phenalkamine Hardeners. The distinctive qualities of these hardeners have complemented the technical abilities of the company and its management in achieving rapid growth in the industry. Phenalkamine Hardeners are unique hardeners with inherent property to cure epoxy resins at low temperatures down to 0°C under high humidity with surface tolerance and adequate flexibility. As a result, Phenalkamine Hardeners have an edge over both polyamides and polyamines in the field of mainly Marine & Protective Epoxy Coatings.

Tetramethylthiuram disulfide

Tetramethylthiuram disulfide compound is used as a fungicide, seed disinfectant, bactericide, animal repellent, insecticide. It is used as a primary and secondary accelerator or as a sulfur donor (vulcanizing agent) in most sulfur-cured elastomers in rubber industry. It is also used in the treatments of chronic alcoholism with cause of acetaldehyde, a breakdown product of alcohol, to accumulate in the blood. It is a peptizing agent in sulfur-modified polychloroprenes. It is used in soaps and rodent repellents and as a nut, fruit and mushroom disinfectant.

Tetrapotassium Pyrophosphate

Tetrapotassium Pyrophosphate used in food processing of emulsifier, organization, quality improver,cyanogens plating and surface treatment, paint coating, detergent,dispersant, slow granule.

Thulium Oxide Purified 99.9%

Thulium oxide is white powder with slightly green color, which turns into red with lustre after heating and it turns into yellowish white again if longer heating. It is rare earth oxide. It is insoluble in water, but dissolve in strong acid slowly. Tm3O3 absorb CO2 and H2O in air to form subcarbonate salts.

Thulium Oxide

Applications

Thulium(III) oxide mainly applies to make portable X-ray transmission device. It acts as control material in reactor.

Thulium trioxide is raw material for X-ray luminescent materials, garnet laser material, rare earth glass laser material and magnetic bubble.

Yttrium Oxide Purified 99.9%

Yttrium oxide is white to light yellow powder, which is a kind of rare earth oxides. It is insoluble in dilute acid, however nearly insoluble in water.

Yttrium Oxide

Applications

Yttrium(III) oxide granule can apply to thermal spray. For this application, it process into spherical large particle to get great flow ability. It should guarantee the whiteness too. Normally the production method is granulation.

Yttrium trioxide is important material for magnetic material for microwave and military project, which is also for optical glass. It can improve the refractive index of special glass and reduce dispersion index. So it is raw material for high brightness fluorescent powder for large-screen television and coating of other kinescope.

Yttria apply to produce thin film capacitor , special refractory material, high pressure mercury lamp, laser, memory parts and other magnetic bubble material. It is also for artificial laser crystal and superconductive material.

Yttrium(III) oxide powder is additive for lanthanum series glass and high temperature resistance and rediation resistance optical glass. It is also important additive for silicon nitride engineering ceramics, zirconium dioxide engineering ceramics, piezoelectric ceramics, photoelectric ceramics, semiconductor ceramics, thermistor ceramics, capacitor ceramics and other functional ceramics.

Yttria powder mainly apply to prepare new magnetic material yttrium iron garnet and solid laser material yttrium aluminum garnet (YAG). It is also a kind of hydrogen storage material.

Zinc 2-Mercaptobenzothiazole

Zinc 2-mercaptobenzothiazole is used in the form of a soluble concentrate or liquid and wettable powder to control mold, mildew, bacteria and fungi which degrade aqueous industrial products, fabrics, and yarns, and slime-forming bacteria and fungi in industrial water systems. It was first registered as a pesticide in the United States in 1955 in an industrial preservative product .It is used for NR,IR,SBR,NBR,EPDM and latex, may be regarded as an intermediate between accelerator M and accelerator DM, used as a secondary accelerator in combination with accelerator PZ and accelerator EZ.
