Acrylates are primarily used to prepare emulsion and solution polymers. The emulsion polymerization process provides high yields of polymers in a form suitable for a variety of appHcations. Acrylate polymer emulsions were first used as coatings for leather in the eady 1930s and have found wide utiHty as coatings, finishes, and binders for leather, textiles, and paper. Acrylate emulsions are used in the preparation of both interior and exterior paints, door poHshes, and adhesives. Solution polymers of acrylates, frequentiy with minor concentrations of other monomers, are employed in the preparation of industrial coatings. Polymers of acryHc acid can be used as superabsorbents in disposable diapers, as well as in formulation of superior, reduced-phosphate-level detergents. 

Latex describes the type of resin or binder used. Exterior paint usually contains 100% acrylic latex emulsions, which usually are copolymers of methylmethacrylate with butyiacrylate or 2-ethylhexylacrylate. This combination stands up well against uv radiation. Interior paint has no uv requirement, and the best combination for cost is a copolymer of vinylacetate and acrylates. Many other formulations are availabledepending on the use and quality desired. 

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. 

Alkyds are used for finishing metal and wood products but not to the degree previously used. Their durability to interior exposure is good, but their durability to exterior exposure is only fair. Because of their formulating flexibility, they are used in fillers, sealers, and caulks for wood finishing. They are still used for finishing by the machine tool and other industries. Alkyd-modified acrylic latex paints are excellent architectural finishes. 

Significant improvements have been observed in the properties of alkyd resin after modification (grafting) with acrylates. The incorporation of MMA into alkyd at a level of 30-40% yields a binder suitable for formulation of high performance exterior paints [80]. 

RHOPLEXTM 4400 acrylic polymer can help you develop plasticizer-free caulk and sealant formulations, which result in products with reduced dirt pickup, glossing, mildew growth and paint discoloration. This novel polymer also helps provide excellent exterior durability and good adhesion to a variety of...
