Corrosion is a natural phenomenon. Due to various types of pollution, corroding factors are on the increase. Hence corrosion prevention is of prime importance in day-to-day activities. One of the natural products with versatile utility in prevention of corrosion in CNSL (Cashew Nut Shell Liquid). This oil is available in plenty from cashew industry as a by-product. CNSL is treated and polymerized to give resins which will act as good coating materials. These resins are used in anti-corrosive protective coatings.

The most important use is in painting marine vessels and finishing boats. These paints are used in chemical plants for protecting the machinery from corrosion. It is also used in structural application, where more exposure to heat and sun-light is there.

Market Potential

There is good market potential for these type of primers in the country; more so in the coastal states where finishing boats and vessels are in plenty. As Chemical industry is expanding rapidly, the concept of giving protection to chemical plants is also on the increase. As more and more stress is laid on preventive maintenance, increasing use of anti-corrosive paints is anticipated.

Technical Aspects

Process of Manufacture

The paint manufacture consists of the following basic procedures

  • Mixing the pigment with sufficient vehicle (Resin Solution) to make paste which has the correct consistency for grinding.
  • Grinding the paste in a mill until the aggregates are broken down as indicated by the 'fineness of grind' test.
  • Letting down the ground paste with the remainder materials in the formula.
  • Tinting the batch to the required colour.
  • Testing to determine physical properties and performance requirements.
  • Straining, filling and packing.

In some cases, mixing and grinding are done in the same equipment. The term grinding is commonly used but the actual term is dispersion. Actually, grinding means reduction in size of the ultimate particles of pigment which does not occur in the large majority of cases. The purpose of grinding is to break down the aggregates and to disperse the ultimate particles in the vehicle. The work required for dispersion is performed by the mill or dispersing equipment, and it may be facilitated by addition of grinding aids. The degree of dispersion in a batch of paste being ground usually is determined with a hegman grind gauge.

The gauge reading at this location is taken as a measure of the degree of dispersion of the pigment. The dispersion reading for enamel paint should be at least 7 on hegman gauge whereas a flat paint may be in the range of 4 to 6 hegman gauge.

The dispersion force or action is different in the various types of equipment. In some cases, it is chiefly a shearing action in the others, it is attrition of pigment aggregates against one another, and impact or crushing occurs to a limited extent. The most common action is shearing which is a lateral motion such as cutting or tearing.

High molecular weight is necessary for high viscosity and strong back, but large molecules do not wet the particles or penetrate the aggregate as efficiently as small molecules. For this reason volatile solvents appear to wet pigments quite readily. However, a good dispersion in a solvent may flocculate when the vehicle is added in the let down stage, therefore, enough resin is used in a solvent dispersion to coat the pigment particles and prevent flocculation.
