Alkyd resins emulsions

Acrylid resin dispersions alone or mixed with alkyd resin emulsions are used for waterborne products.

Both regulatory limits on the amount of organic solvents allowed in paints and advancements in alkyd resin technology have resulted in the development of higher soHds alkyd resins that requke less solvent for dilution and viscosity reduction. In addition, developments of water-reducible alkyds and alkyd emulsions have resulted in alkyd-based paints that requke less organic solvent in thek formulations.

All members of this pigment family share good lightfastness, combined with poor solvent and migration resistance. These properties define and limit their application. Monoazo yellow pigments are used extensively in air-dried alkyd resin and in emulsion paints, and certain inks used in flexo and screen printing. Other applications are in letterpress and offset inks, as well as in office articles. 

Additional studies were made of the oil as an insecticide and ovicide, when applied as an emulsion. In all cases the isoparaffinic fraction was solubilized by the addition of Triton B-1956, a nonionic phthalic glycerol alkyd resin. The emulsions were applied to the point of mnoff (200 to 400 gallons per acre). The results of these tests are shown in Table I. 

The exercise of preparing emulsions using oils-mixed additives is well described in Emulsification and Polymerization of Alkyd Resins (Gooch 1980, 2002), although without the addition of acidic or cationic agents for the purpose of inhibiting or destroying bacteria. 

Both aqueous polymer-based systems (latex), made by emulsion or dispersion polymerization, and oil-modified alkyd resin-based systems are still in wide use [781], Table 12.2 shows the composition of a typical water-based emulsion paint. There is a wide variety of coatings, ranging from broad applicability to highly specialized, including latexes, amino resins, isocyanates, epoxy resins, acrylic resins, polyester... 

Wang et al. [98] carried out macroemulsion and mini emulsion polymerization of acrylic monomers in the presence of alkyd resins. Miniemulsion and macroemulsion polymers were produced using a commercial medium soya-linseed alkyd and a mix of acrylic monomers consisting of 50% BA, 49% MMA, and 1% acrylic acid (AA). PMMA polymer with a weight average molecular weight of 100,000 was used as the costabilizer. Alkyd levels were 5, 30, 60 or...

Several industrial systems involve emulsions, of which the following are worthy of mention. Food emulsions include mayonnaise, salad creams, deserts, and beverages, while personal care and cosmetics emulsions include hand creams, lotions, hair sprays, and sunscreens. Agrochemical emulsions include self-emulsifiable oils that produce emulsions on dilution with water, emulsion concentrates with water as the continuous phase, and crop oil sprays. Pharmaceutical emulsions include anaesthetics (O/W emulsions), hpid emulsions, and double and multiple emulsions, while paints may involve emulsions of alkyd resins and latex. Some dry-cleaning formulations may contain water droplets emulsified in the dry cleaning oil that is necessary to remove soils and clays, while bitumen emulsions are prepared stable in their containers but coalesce to form a uniform fihn of bitumen when apphed with road chippings. In the oil industry, many crude oils (e.g.. North sea oil) contain water droplets that must be removed by coalescence followed by separation. In oil slick dispersion, the oil spilled from tankers must be emulsified and then separated, while the emulsification of waste oils is an important process for pollution control. 

The highly hydrophobic alkyd resin can serve as both reactant and coemulsifier (hydrophobe) in the mini-emulsion polymerization of alkyl (meth)acrylates [80, 110]. The strong synergism in the minidroplet nucleation was observed when highly hydrophobic unsaturated alkyd resin was used as the hydrophobe (>20 wt %). This feature is very different from the conventional coemulsifiers, such as long-chain alkanes and alcohols, that are effective around at 2 to 4%. 

It is particularly good for colloids, emulsions and particles. Samples separated thus far include lattices, latex aggregates, silica sols, alkyd resins, perfluorocarbon emulsions, milk, carbon particles, hematite, clay, water-borne particles, liposomes, subcellular particles, viruses, and polymerized proteins.
