Acrylic paint formulation

A typical exterior acrylic paint formulation see Appendix A) was thickened with a commercial HASE thickener that contained 5.23 meq/g of carboxylic acid functionality (4). This thickener was modified with 1 to 25 lb (1 lb = 0.4536 kg) of zinc oxide (French process) in the mill base in one set of paints and with post-added zinc ammonium complex such as acetate, carbonate, bicarbonate, or glycinate in another set of paints.

The synthetic isoparaffins are suitable solvents for alkyd and acrylic paint formulations. These virtually odorless solvents and their low surface tensions offer improved flow and wetting properties to the paints. The excellent wetting characteristics of these solvents are desirable in formulations such as furniture polishes, car polishes, and waterless hand cleaners. The low surface tension of these solvents reduces the amount of surfactants needed in emulsified products and affords improved wetting of pigments in ink and coating formulations. The isoparaffins are used as an inert process solvent in the manufacture of polyolefins and certain rubbers. In the slurry polymerization process the isoparaffins afford solvency for the Ziegler-type catalyst and the ethylene monomer, but no solvency for the polyolefin polymer product. 

Other additives used to aid thermoplastic acrylic paint formulation are pigment wetting agents, and silicone slip and flow aids.

Hairspray is formulated to hold hair in place and keep it shiny, without flaking off, without failing, even in humid conditions. Yet it must retain the ability to be washed out of the hair easily for at least forty-eight hours, and it must not clog the spray can s nozzle. Complex polymers are needed to perform all of these tasks well. The basic building blocks of these polymers are the same ones found in acrylic paints and white glue. But they are put together in a different way. 

The appropriate amount of biocide carrier composition needed to yield a specified dry film concentration of biocide was added to a fixed quantity of waterborne acrylic paint and premixed using a high-speed disperser. This dispersion was then transferred to a Silverson-type mixer to obtain a finer dispersion. At this stage the influence of addition of silica or zeolite on the physical/mechanical properties of the paint film was assessed, though only minor changes in properties were noted, which could be eliminated by appropriate adjustments to the paint formulation.

Maleate Surfmers. Surfmers with allylic, acrylic and vinylic moieties tend to homopoly-merize and produce water-soluble polyelectrolytes if used above their CMC. This has shifted researchers attention to maleic derivatives that do not homopolymerize at normal temperatures because their ceiling temperature is too low. Tauer and co-workers have pioneered the synthetic work [4,15] which led originally to compounds like those given in Figure 6.49. An example of maleic-derived Surfmer used in emulsion polymerization lattices is reported in [16] and the advantages provided in commercial paint formulations are discussed later. 

Acrylic acid derivatives treated with heparin are used to coat surfaces of clinical equipment. Acrylic acid is also used as a copolymer component in aerosol hair spray, in plastics, in molding powder for signs, in paint formulations, in leather finishing, in paper coatings, and in latex applications to prevent premature coagulation. It is also used in the production of hydrogels used for contact lenses.

Application. Acrylic paints are used in many different areas and applied by all commonly used methods. Recent developments (low-solvent paints and aqueous dispersions) require special formulation.

This paper is not concerned with the detail of paint formulation, but the polymer types most widely eneountered are aUcyds, polyurethanes and nitrocellulose in solvent based systems, and acrylics, styrene-acrylics, and copolymers of vinyl acetate in water-based coatings. 

Commercial electropainting only dates from the early 1960s and the first processes to be introduced used anodic deposition. Some typical paint formulations would contain (i) polycarboxylic acids based on acrylic acid as monomer solubilized by an organic amine, (ii) alkyds, i.e. branched polyesters based on naturally occurring long-chain carboxylic acids and polyalcohols, e.g. glycerol, and (iii) epoxy resins based on phenols, e.g. 

A series of conductive electroactive paints were prepared by blending polypyrrole colloids (20-80 wt %) with an acrylic latex formulation in water [136]. Dip coating of lead, stainless steel, and Zincalume substrates resulted in strongly adherent electroactive coatings having electrical conductivities. similar to carbon-filled paints. The addition of the CP colloids to the latex paint increased adhesion.
