and loss of dry upon storage of alkyd resin emulsions. The oil length was 83%, and the acid value was between 6 and 9 mg KOH/g alkyd. For further reference in the text, this resin will be designated LO83. The alkyd resin used for the film formation study was based on pentaerythritol, phthalic anhydride, and tall oil fatty acids.

Alkyd resin is a fatty acid modified polyester synthesized by polycondensation reaction of fatty acid, polyol, polybasic acid and monobasic acid, which has attracted more and more attention due to its cheap raw materials, excellent adhesion, high gloss and remarkable wettability [2,4]. Alkyd resin has always
modified alkyd resin has been done [5,6,7,8]. It has been observed that, when a 30% concentration of a ketone resin was blended to an alkyd resin; a significant …
Chemically, alkyd resins have been defined as reaction product of condensation polymerization of polyhydric alcohol, polybasic acid, and monobasic fatty acid (saturated or unsaturated; Figure 1 ). They are best classified according to the amount of fatty acid and phthalic anhydride present ( Table 1) [ 1 ]. Table 1 Alkyd classification. …

design space that was generated using design of experiment software. The alkyd resins were then emulsified using a proprietary surfactant package. The base resins were used as controls. Table 2 presents the different alkyd emulsions and some of their wet properties. Note that all alkyd emulsions shown had particle sizes ≤300 nm.
GE introduce Glyptal® resins (glycerol phthalate) DuPont introduce alkyd resin (glycerol/phthalic anhydride/linseed oil). Alkyd modified oil paints and then alkyd paints were eventually used on cars and appliances. 1927 R.

ALKYD RESIN . 1. INTRODUCTION . Alkyd resins are any of a large group of thermoset resins that are essentially Polyesters made by heating polyhydric alcohol with polybasic acids or their anhydride and used chiefly in making protective coatings good weathering with properties. These resins are useful as film forming agents in paint, varnished ...

the acid value of DCO alkyd resin tended to decrease more slowly compared to other oil-based alkyd resins. As a result, DCO alkyd resin has the highest acid value at 5 hr of reaction. This could be caused by the highest amount of free acid in pure DCO (see Table ablTe 1. Characteristics and price of oils used in this work ypeT of oil Acid value
