Protective coatings architectural

Covalent polymer networks or (Class II) crosslinked macromolecular architecture polymers rank among the largest molecules known. Their molecular weight is given by the macroscopic size of the object for instance, a car tire made of vulcanized rubber or a crosslinked layer of protective coating can be considered one crosslinked molecule. Such networks are usually called macronetworks. On the other hand, micronetworks have dimensions of several nanometers to several micrometers (e.g. siloxane cages or microgels). 

PFEVE-based coatings are used as protective coatings for large architectural structures, such as office buildings and bridges where on-site coating and curing are... 

The major coatings markets in the United States consist of architectural coatings (consumer and decorative), product finishes (maintenance/protective coatings for bridges, industrial machinery, etc.), and special-purpose coatings, such as automotive finishes ((OEM) and refinish) (Table 29.1).1... 

And finally, the very promising application of hydrogels as cushions but also as protective coatings for the tethered membrane architectures, eventually allowing even for operations in air, is presented and discussed. 

Long oil drying alkyd resins are used as binders for architectural and do-it-yourself paints, and are mainly modified with soybean oil. In the absence of direct light, they do not yellow as much as linseed oil alkyd resins and are less expensive than safflower oil types. Long oil linseed oil alkyd resins are principally used in corrosion protection coatings and colored architectural coatings.

Chromic acid anodization< ) is widely used to improve the corrosion resistance of aluminum surfaces, e.g., on window frames and in other architectural applications. Similarly, it was thought that the use of a good protective coating on the aluminum would protect the metal interface and thereby increase the bond durability of the joint. Although CAA is not as popular as FPL and PAA treatments in the United States, it is widely used for aerospace applications in Europe. 

In conclusion, these unprecedented properties of PAMAMOS dendrimers and their networks, clearly result from the synergism of two distinctly different chemical compositions and unique dendrimer molecular architecture. These materials provide provoking new possibilities for applications in various fields, including optoelectronics, protective coatings, separation processes, etc. 

Polyimides are an important class of polymers for high temperature aerospace applications. Thin polyimide films are ideal candidates for protective coatings on antenna reflectors and other electronic applications. Their properties, both physical and electrical, are expected to be strongly influenced by their morphology. We have developed a novel technique for monitoring microstructural characteristics of thin polymer films. It is based on the sensitivity of the positron lifetimes to the molecular architecture of the polymers. Specifically, positron lifetimes can be used to calculate free volume hole radii and free volume fractions in the test polymers. A free volume model has been developed to calculate dielectric constants of thin polyimide films. It has been tested on a series of special purpose polyimide films developed for aerospace communication networks. The results are described in the following sections.
