Abstract

Alkyds are the work horse of paint industry. In order to obtain desired film properties, alkyd resins are frequently modified by other resins and polymers either by physically blending them or chemically incorporating them. Some of the recent physical modifications of alkyds have been described in this first part of the article. The chemical modifications will be described in the second part.

Abstract

In order to obtain desired film properties, alkyd resins are frequently modified by other resins and polymers either by physically blending them or chemically incorporating them. Some of the recent physical modifications of alkyd have already been described in the first part of the article. In this second part, the different types of resins and polymers used for the chemical modifications of alkyd resin are reviewed. A critical discussion on generally recognised advantages and disadvantages of the resultant coating from each modifier is described. Their use in surface coating industry are enumerated. Types of modifier to be used for improving a particular property in the coating are also suggested.

Abstract

Polystyrene glycol was prepared and incorporated into linseed alkyd. Compatibility of polystyrene glycol and alkyd was investigated. It was found that 20 per cent polystyrene glycol could successfully be blended with linseed alkyd. Film properties of these blends were examined and compared with those of plain alkyd. It was observed that polystyrene glycol modified linseed alkyds were superior, in film properties, to the plain alkyd except in solvent resistant property.

Abstract

Polystyrene glycol was prepared and incorporated into nigerseed oil and castor oil alkyds representing semi‐drying and non‐drying type alkyds respectively. Compatibility of polystyrene glycol with these alkyds was investigated. It was found that 11 to 12 per cent polystyrene glycol could successfully be blended with these alkyds. In order to determine usefulness of these polyblends, film properties were examined and compared with those of plain alkyds. It was observed that polystyrene glycol modified alkyd blends were superior in film properties as compared to plain alkyds.
