Zinc Stearate SPL is produced using most modern manufacturing facility situated at Kota (India) under ISO 9000 certified systems. We have privilege to be associated with one of the oldest and largest manufacturers of Metallic Stearates in India. Zinc Stearate SPL is manufactured from the very best superior quality VEGETABLE BASE raw materials using double decomposition method adopting strict process control.This grade is highly recommended for special type of applications where quality is the most desirous factor like Transparent PVC masterbatches, Polystyrene compounds, UF/MF/Bakelite molding powders, Ferrites, Talcum Powder, Cosmetics and Pharmaceuticals, EVA formulations, Lacquer sanding agent, Dental cements etc.Zinc Stearate SSPL enhances flowability in ferrites when used as lubricant before spray drying.It reduces clogging of sand paper when incorporated in sanding sealers.

Applications

Cellulosic fibres can be treated with Skaywhit PUM at practically all stages of manufacture in acid and alkaline baths.Due to its medium to low affinity it is particularly suited for padding.
Softening: Non-ionic softener has the least effect on whitened articles.This may be applied either with skaywhit PUM or separately as an after treatment.
Cationic softeners weaken the white effect slightly but this can usually be compensated by increasing the amount of optical whitening Agent.
For low pH application which involves resin treatment, Skaywhit PVR and Skaywhit STM are recommended.
A few trial applications should be made to establish the quantity best suited.

Stripping

To remove the slight brownish shade which occurs and to avoid any subsequent yellowing it is advisable to give the goods a final mild peroxide bleach containing an anionic detergent.If the goods are to be optically whitened again most of the skaywhit brands for cellulosic fibres can be added to this bath.

Introduction and scope

Light Basic Magnesium Carbonate is used in large quantities in rubber, ink, cigarette, paper and cosmetic industries. It is also used in preparing soft drinks, especially offervascent lemonade ginger,etc. In breaking aromatic oil and as a filler for essences.It is especially useful for tablet preparations in confectionary, It is a part of baking and custard powder.

Due to its marked absorptive power, it is incorporated in special soaps and explosives.Free flowing table salt has a coating of magnesium carbonate to prevent caking.It is extensively used as an insulation material along with asbestos like materials for steam or heat conveying equipments and system.
