• Name: Ammonium SUlphate
• Application: Industrial Use

Ammonium sulphate is one of the oldest of N and S-containing fertilizers, and is still popular around the world. Ammonium sulphate is mostly produced as a co-product of other industries. An estimated 70% of global output originates from the production of caprolactam, an intermediate for the manufacture of synthetic fibers. A small amount is recovered from coke oven gas, with most of the remainder produced synthetically from sulphuric acid and ammonia. The product is used directly or for blending with other fertilizers. Improvements in the ammonium sulphate formulation processes allow for increasing shares of larger-sized granular material, which is easy to handle and suitable for bulk blending. This has greatly increased application options and spreading performance. Ammonium sulphate is also popular in India in the manufacture of compound fertilizers, now deliberately being added to increase their S content. The main advantages of ammonium sulphate are low hygroscopicity and chemical stability. It is a good source of both N and S. Its use may be undesirable in acidic soils already in need of liming and when it is applied at nitrogen rates. Also, when applied as direct application as an N source, much more S is applied incidentally than is required by most crops. Ammonium sulphate now can be obtained as a granular material, which is easy to handle and suitable for bulk blending with other fertilizer materials. Segregation problems can occur in bulk blends when its product size is not well matched with those of N, P, and K materials. This difficulty can be minimized by carefully controlling uniformity and sizing of ammonium sulphate used in blends. It can also be used in clear liquids to make solutions of fertilizer containing N and S. Sulphur concentrations in solutions based on ammonium sulphate can vary from 1%-9%. In NPS blends formulated with ammonium sulphate, the usual S concentrations range from 1% to 3%.

832B is a general purpose, rigid, 2-part black epoxy that provides extreme environmental, mechanical and physical protection for printed circuit boards and electronic assemblies. Due to its low mixed viscosity, 832B can easily penetrate small gaps and cavities. It also provides excellent electrical insulation and protects components from static discharge, vibration, abrasion, thermal shock, environmental humidity, salt water, fungus, and many harsh chemicals. This black epoxy potting compound has a convenient 2:1 volume mix ratio, making it compatible with most dispensing equipment. 832B can be cured at room temperature or higher.   For a 1:1 mix ratio consider 832HD. For clear 2-part epoxies try 832C or 832WC. We also offer flexible, thermal and high temperature epoxy potting compounds. Our 2-part flame-retardant epoxy potting compounds are 834B, 834HTC and 834FX. For a 1-part epoxy try 9510. We also offer polyurethane and silicone potting compounds.
