Aqueous Emulsion Coatings

An emulsion is a dispersion of one liquid in another the best-known example is milk, in which fat droplets are emulsified in water. In an emulsion coating, a liquid polymer is dispersed in water. Many alkyd and epoxy paints are examples of this type of coating. [Pg.56]

Various types of surface coating materials can be used with sohd fiber paperboard to achieve desired package properties. The coatings and treatments described for cormgated paperboard apply to sohd fiber paperboard as weU. Various solvent and aqueous-based polymeric emulsion coatings are also commonly used (see Emulsions). [Pg.519]

Vinyl acetate is polymerized in aqueous emulsion and used widely in surface coating and in adhesives. Copolymerized with vinyl esters of branched carboxylic acids and small quantities of acrylic acid, it gives paint latices of excellent performance characteristics. G. C. Vegter found that a coagulum-free latex of very low residual monomer content can be produced from a mixture of an anionic and a nonionic emulsifier according to a specific operating procedure. The freeze/thaw stability of polymeric latices has been investigated by H. Naidus and R. Hanzes. [Pg.9]

The addition of sodium chloride to aqueous spray-coating solutions containing hydroxypropyl cellulose or hypromellose suppresses the agglomeration of crystalline cellulose particles. Sodium chloride can also be used to modify drug release from gels and from emulsions.It can be used to control micelle size, and to adjust the viscosity of polymer dispersions by altering the ionic character of a formula-... [Pg.671]

Filler-free formulations of two-component silicone rubbers crosslinkable by condensation or addition are utilized, with or without added solvent, for the coating of papers and plastic foil, optionally as an aqueous emulsion, e.g. for strippable paper for self-adhesive labels or packaging foil for bitumen. Vulcanization is carried out at high temperature (100 to 180°C), to attain as short hardening times as possible. [Pg.320]

Emulsion polymers (latexes) are the most commonly used film formers in the coating industry this is particularly the case with aqueous emulsion paints that are used for home decoration. These aqueous emulsion paints are applied at room temperature, when the latexes coalesce on the substrate to form a thermoplastic film. Occasionally, functional polymers are used for crossUnkirig in the coating system. The polymer particles are typically in the submicron range (0.1-0.5 pm). [Pg.206]
