Architectural surface coating

In addition to plastics materials, many fibres, surface coatings and rubbers are also basically high polymers, whilst in nature itself there is an abundance of polymeric material. Proteins, cellulose, starch, lignin and natural rubber are high polymers. The detailed structures of these materials are complex and highly sophisticated in comparison the synthetic polymers produced by man are crude in the quality of their molecular architecture. 

The stabilizing of aqueous latexes succeeded by using emulsifiers (anionic, nonionic) and/or their mixture, steric stabilizators (polyvinyl alcohol (PVOH), hydroxyethyl cellulose, polyethylene glycol, new protective colloids etc.), and polymerizable surfaces active agents, in general. Vinyl acetate (VAc) emulsion homopolymers and copolymers (latexes) are widely used as binders in water-based interior and exterior architectural paints, coatings, and adhesives, since they have higher mechanical and water resistance properties than the homopolymers of both monomers [2, 4, 7]. 

Linings and liquid surface coating systems for architectural fabrics. .. 

To synthesise polymers with unusual properties from existing basic monomers one needs to place the monomer units in ordered arrays rather than at random. Thus polymer architecture control remains an important area of research. Possible structural elements include block, graft and comb copolymers as well as star and dendritic/hyperbranched topographies. Potential for such structures in the surface coatings and adjacent industries include use as... 

Exploiting Acrylic Polymer Architecture in Surface Coatings Applications... 

This can be viewed either starting from the top left (technology push) or the bottom (market pull). Starting with synthesis, why alter polymer composition Control of polymer chemistry and synthesis leads to a defined polymer architecture, i.e. the chemical and physical composition of a polymer chain. This architecture influences the basic properties of bundles of polymer chains, which then correlate with applied properties. The polymerisation process may affect the polymer architecture produced and the coating process will influence both the basic and applied properties. Basic properties are independent of the application whereas applied properties may be application specific. For surface coatings applications, the overall performance will be influenced by other raw materials in the formulation, depending on the nature of the individual components and the interaction between them. Improvement in specific...
