Overview

This original research, published here for the first time in book format, describes in detail an entirely new process for preparing emulsions and alkyd resin emulsions, leading to many applications, foremost among them the formulation of new paints. This research has also spawned the international field of alkyd and alkyd-hybrid miniemulsions. Pioneering technology is presented for the emulsification of alkyd resins and vegetable oils used in coatings, adhesives, and inks applications.
Essential technical information is provided for researchers and manufacturers involved in the emulsification of resins, oils, and pigments. Emulsification and Polymerization in Alkyd Resins is an indispensable reference book for every type of coatings and resins manufacturer or research group.

Synopsis

Emulsification of vegetable oil-based resins was a daunting task when the author began his research, but the subsequent technology spawned a generation of stable emulsions for waterborne coatings based on vegetable oil-based alkyd resins, oils and fatty acids. Autoxidative polymerization of emulsified alkyd resins is an innovative and original contribution to emulsion technology, because conventional emulsion-polymerization is not applicable to alkyd resins. Emulsified alkyd particles are polymerized while dispersed in stable aqueous media—an original and patented innovation. Smooth and fa- drying alkyd coatings are generated from non-polymerized emulsions and air-dried with conventional metal driers, and have met with marketing success. The pre-polymerization innovation for emulsified alkyd particles provides very fast air-drying coatings that have potential markets for interior architectural latex coatings and waterborne pressure-sensitive adhesives and inks. The author demonstrates his knowledge of chemical reaction kinetics by employing a combination of oxygen concentration, internal reactor pressure and other reactor variables to finely control the rate and degree of autoxidative polymerization. He meticulously calculates surfactant chemistry by measuring hydrophile-lipophile balance values, and solubility parameters to emulsify characterized resins. The relationship between hydrophi- lipophile values and solubility parameters is shown in explicit equations. Homogenization equipment used during the course of this research to generate emulsions is shown in detailed drawings together with concise particle size and distribution data. The author reports research spawned internationally by his research in the fields of alkyd-acrylic hybrids, polyester and oil-modified urethane resins.

From The Critics

An explanation of a process by which renewable raw materials (such as soybean oil) could be used in waterborne surface coatings (i.e. paints) written by one of the scientists who patented the process. The disadvantages of alkyd-solvent coatings are the objectionable solvents which produce volatile organic compounds that are restricted by the Environmental Protection Agency, so the difficulty comes with finding a way that alkyds can be dispersed in water and wet applied to a substrate without using solvents. The solution is answered by dispersing the alkyd resins in water by carefully selected surfactants and then mechanically homogenizing them to form a stable emulsion. Then the alkyd-water emulsion is oxidatively polymerized to crosslink, causing it to form gel-like particles that flow together during evaporation of water forming a continuous film. Annotation c.
