Solvent-free coatings

High Solids Costings. High soHds coatings resemble the technology of solvent-free coatings but the compositions contain ca 70% by volume of soHd resin and are modified by reactive diluents, low viscosity multifunctional resins, or backbone stmctures other than the bisphenol A moiety. [Pg.370]

Successful solvent-free chemical syntheses have been reported for a variety of small molecules, both with and without the use of microwave irradiation, and for some polymer preparations (Varma, 2000). Solvent-free coatings formulations have also been developed. [Pg.115]

As with cleaning, many researchers are looking toward solvent-free coatings as the answer to solvent replacement. [Pg.239]

An epoxy resin formulation completely free of organic solvent was applied to carbon steel coupons using supercritical carbon dioxide (CO2) as the volatile solvent. Sleet coupons coated in this manner were compared to coupons coated with a standard military specification marine primer (MlL-P-24441) during exposure to aerated 0.5 nrl sodium chloride (NaCl). The solvent-free coating protected the steel from corrosion in this environment as well, if not better than, the solvent-based primer (Kendig et al., 1999). [Pg.246]

Examples of aqueous coating solutions include water-soluble low molecular weight cellulose ethers, emulsion polymerization latexes of polymethacrylates, and dispersions of water-insoluble polymers such as ethyl-cellulose in the form of pseudolatex. These solvent-free coating solutions provide a range of different coatings... [Pg.2330]

The coating must also be solidified very rapidly once it is applied to the fiber so that it will offer protection when the capstan is reached. This requirement rules out solvent-containing formulations for all but the thinnest coatings, because solvent removal is a slow process. Solvent-free coating formulations that are rapidly cross-linked by thermal activation or by UV radiation can be used very successfully. Thermoplastic hot-melt systems that solidify quickly upon cooling are also viable. The material systems of choice for this application depend upon both coating-application and coating-performance considerations. [Pg.912]

The utility of blending urethane polymers with other polymers (e.g., acrylics) in a water dispersible media for environmentally friendly coatings has been discussed [Loewrigkeit, 1990]. Blends of separate water dispersions of the constituents generally do not lead to useful properties. Simultaneous polymerization of the acrylic and the urethane results in a desirable property balance and solvent-free coating systems. Commercial, urethane-acrylate water based coating (Flexthane Air Products and Chemicals, Inc.) has been noted by Gruber [1992]. [Pg.1190]

Coatings containing styrene cure in virtually any thickness as the styrene which initially acts as a solvent polymerises with the double bonds of the UP resin and is incorporated into the paint film. As only a small proportion of the styrene evaporates, this virtually solvent-free coating yields films with extremely good body [2.99],... [Pg.57]
