PRODUCT INTRODUCTION

Calcium Stearate is a white free-flowing powder that insoluble in the water and very hygroscopic. It has water-repellent properties, anti-foaming, and anti-caking qualities. Calcium stearate has excellent dispersion properties and controlled particle size, resulting in its widespread use as a lubricant in plastics production and the process of extrusion laminating plastics and metals.

SAFETY & HANDLING

  1. Calcium Stearate is unlikely to present any significant health or safety hazard when properly used in the recommended application. It may cause an allergic skin reaction and respiratory irritation. Ensure good ventilation at the workplace. In case of accidental eye contact, flush with large amounts of water and call a physician. If swallowed, call a physician.
  2. Calcium Stearate is not corrosive nor flammable. However, these products are available in powder form and – like all powders – should be handled in such a manner as to minimize dusting. Otherwise, an explosive hazard could develop. Avoid all sources of ignition when handling this product. Avoid contact with skin and eyes when handling this product. Although metallic stearates are chemically stable, they should be kept away from strong oxidizing agents. Wear protective gloves.
  3. For storage matter, it is recommended that Calcium Stearate be used one years after the date of manufacturing.

Industry

Applications

1

Building

Applied as hydrophobic agent in mortars and plasters

2

Lacquer

Matting agents and abrasives

3

Lubricant

Thixotropic agents for the production of lubricants and greases

4

Latex and Rubber Process

Used as anti-blocking agent

5

Paper

Lubricant agent to provide a good gloss, avoiding dust and cracks in the paper and cardboard production process.

6

Metal

Lubricant for powder metallurgy, wire drawing and tubing

7

Paints

Its purpose is to form a gel, stable with resin and solvents, thus preventing pigments and fillers from settling.

8

Concrete

Fluorescence containment agent for cement products used in the production of concrete masonry units, ie paver and block, as well as waterproofing.

9

Food & Feed

Used as anti caking agent

10

Pharmaceutical Industry and Personal Care 

Tablet mold release agent, non-stick agent and gelling agent.

11

Textile

Calcium stearate is applied for dry impregnation and as an antistatic agent.

12

PVC Processing

The main application is in rigid PVC compounds. Calcium stearate is used in combination with zinc stearate in non-toxic stabilizers.

13

Printing ink industry

Calcium stearate as swelling and suspension aids for other additives such as pigments. They are also employed as lubricants and release agents for pastels and as matting agents for gravure inks. They are added to cement and fillers on account of their excellent oil-binding properties. During the production of waxes and the processing of liquid wax compounds, they act as suspension agents and increase water repellency. They are added as anti-caking agents to different types of fillers and very hygroscopic salts and also to improve water resistance. The Metal-Processing Industry uses metallic stearates as lubricants, release agents, and dry- film lubricants.

14

Polyethylene and Polypropylene Manufacture and Processing

Employed mainly as acid acceptor and lubricant

15

Polyamides and Polycarbonates

Used as lubricant to improve fluidity

16

Polyesters

Used as internal lubricant
