Chemtex Speciality Limited

Sulfamic Descalant is an efficient descaling agent and is used for cleaning of a variety of industrial equipments and domestic appliances. Chemtex’s Sulfamic Descalant can be used for removing water and process scales from industrial equipments. Broadly these find use in the chemical and fertilizer industry, dairy and food equipments, brewery equipment, marine equipment, sugar industry etc.

Chemtex’s Sulfamic Descalant is non-inflammable and, unlike Hydrochloric Acid, does not give off obnoxious fumes. The safety of Chemtex’s Sulfamic Descalant has been further increased by the addition of corrosion inhibitors and other chemicals to make Chemtex’s Sulfamic Descalant a versatile descaling agent which is safer still in terms of equipment corrosion and safety of personnel.

The field of descaling is wide and the exact application of Chemtex’s Sulfamic Descalant can only be determined after considering the nature and extent of scaling, and the type of equipment that is to be descaled.

Key Features and Benefits
Inhibited product to prevent corrosion while descaling
Better descaling efficiency
Low product concentration required for descaling
Application and Dosage
Chemtex’s Sulfamic Descalant is used in various applications and at different concentration ratio depending upon the amount and type of deposit and system parameters.

Normally for a system with hard scale deposits a 5-20% v/v solution is recommended. Preferably this solution should be made with pre-heated water at 70-80oC. The total volume of solution should be about 1.2 times of water holding capacity of equipment to be descaled. Recirculate the solution for about 6 hours using an acid compatible pump. After descaling it is necessary to passivate system with 2% solution of ALSTASCALETM PS20 into the last rinse and return to normal service.

Important
For extremely rock hard and thick scaling it is recommended to soften the scale prior to descaling by recirculating and soaking 5-10% solution of ALSTASCALETM SS22 for 2-3 hours followed with rinsing with plain water before dosing descalant.
In case of high silica and iron deposits add 2-3 parts ALSTASCALETM SR60 of Sulfamic Acid.
After dosing chemical never heat solution by firing burners.
Handling measures and precautions
Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals. Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. Should not be injected. Please refer MSDS for more details.

Storage
This product should be stored in original containers in cool and dry place, away from sources of heat, flame and direct sunlight. Please refer Technical Data Sheet, Label and MSDS for more details and shelf life.

Corrosion Inhibitors for Multi Metal System do not allow accumulation of reducing agents to the surface of the metal and forms a thin protective film that covers the surface and molecules of the chemical gets adsorbed on the same, making the surface inert and prevent almost all kind of reactions with corrosive agents. These metal corrosion inhibitors prevent attack of acidic components on metal components without interfering with the actual process. The type and concentration of the corrosion inhibitors to be used depend upon the characteristics of metal that is needed to be protected and the operating conditions under which the metal works. Iron, aluminum, copper, etc., all require specific acid inhibitor formulations of corrosion preventative coatings for desired result.
