	abstract = {Acrylic coating is a new type of painting developed in the 50 decade, which is synthesized by co-polymerization from acrylic ester and methyl acrylic acid ester. Germany Rohm \& Haas company began to produce acrylic resin in 1927. In the beginning of 50 decade, U.S. Du Pont company began to research acrylic coating and used it in automobile industry. In the middle of 50 decade, researchers paid attention to the advantages of acrylic painting step by step. In the same time, engineers were succeeded in industrializing acrylic ester, which decreased the cost of raw materials and provided abundant raw material resources for the rapid development of acrylic painting.Acrylic coatings can be made into many types, for example, solvent, aqueous solution, water disperse, powder types by using different monomers, synthesizing different structures and changing processing conditions, processing auxiliaries and prescription. In the view of forming film mechanism of painting, it can be divided into volatile type and cross linking types, no matter that it is either solvent and aqueous types. Because the main absorbed peak of acrylic resin is beyond the sun light spectrum, acrylic painting made from it has some advantages as followings, which other resins do not have, light color and transparence, good weather resistance, heat proof, baking resistance and corrosion resisting.Acrylic coating is the painting that is applied in many fields and the consumption is much more. Abroad large painting companies, for example, British ICI, Germany BASF, American Du Pont and Japanese GuanXi all paid much attention to acrylic painting. Acrylic coating accounts for a high percentage of special in automobile painting and out door wall painting. In our country, acrylic coating was developed very rapidly, and the average increase rate per year was 28\% during 1978-1991, but with a low output. In 1990 the output of acrylic coatings was 11,000 ton accounting for 1.3\% of the total painting output in our country. Compared with American which acrylic coating output was 910,000 ton in 1981 accounting for 19.4\% of total coating output, the ratio is very low. Our output is not suitable to the great consumption market and the huge market potential Experts predict that the demanding amount for acrylic coatings in painting field will be 20,000 ton in 2020, which indicates that acrylic paintings are products with good future.Acrylic resin has good weather resistance, gloss retention and oneself drying at room temperature, but its heat resistance is bad. It is easy to be stick at high temperature, easy to be polluted, devoid of elasticity at low temperature, and brittleness of painted film because of its plastic and lacking cross linking points in molecule chains, which is difficult to form a three dimension cross linking net film. Acrylic resin improved with organic silicane is with acrylic polymeric molecules as main chains and its side chain is silicane or silicone with -OR or -OH groups. Silicone-Acrylic Coating (SAC) with acrylic resin as film combines advantages of acrylic and organic silicon painting and has super weather resistance, good waterproof, salt mist resistance, high and low temperature resistance, pollution resistance, and wash and brush resistance. It can be applied in construction as out-door wall painting for the special demand to weather resistance, as engineering machinery painting, and for the surface corrosion resistance and decoration of port equipment and oceanic construction, which working circumstance is very inferior The properties of SAC are good, and its weather resistance is only next to fluorine coating. Its price is much lower than fluorine coating and it has a huge potential application marketing. Researchers in Japanese, American and West Europe have done much work in its production and application. SAC was developed rapidly last year in our country with the increase of consumption amount of construction painting. But the most of parts are solvent, and there are many problems in using and constructing. Researching and developing super weather resistance and good penetrate high performance coating of latex for building not only come up to with the requiring of current society but also developing trend. SAC is the main kind of super weather resistance coating, which possesses dualism of inorganic and organic coating, combines excellent character of organic silicon and acrylic acid, has outstanding super weather resistance, brush and wash resistance, chemical resistance, and accords with the developing direction with vital force in the world. With the blossom of real estate and the increase of high buildings in our country recently, the demand for construction coating grows from low level to high level.},
