SurfactantsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : It is often assumed that solvent-based sealers give better performance than water-based formulations on concrete because the solvent-based sealers are thought to better penetrate into the concrete matrix. In practice, it can be difficult to measure actual penetration of a sealer into concrete, as dyes and colorants used to highlight the sealer may show different migration properties than the polymeric binder. Confocal Raman spectroscopy mapping has been used to map the depth of penetration of solvent-based, 100% solids, and water-based sealers that employ acrylic and epoxy binders. This mapping shows that neither solvent-based nor water-based formulations showed any significant penetration into the concrete substrate beyond the first few microns of the open surface. A study has also been carried out using a model waterborne acrylic sealer formulation to determine whether additives might influence the penetration of the sealer into the concrete or other factors that could affect the performance of the waterborne coating. This work has shown that the addition of anti-foaming, coalescing surfactants can improve the protective properties of the coating by improving air release and increasing film network formation at the concrete surface.

Traction (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : Painting over joints and the narrow gaps around fasteners is extremely common. When the joint or gap is stressed, the gap opens and the coating over it is subject to very large strains that may immediately or eventually cause it to fail and thus permit corrosion, etc. Improving the design or selection of coatings to overcome this problem requires quantification of the imposed elongation of the coating. A simple coated butt joint geometry, in tension and in bending, is modeled by finite-element analysis to examine how coatings of different modulus respond to the opening of a joint, particularly showing regions where strain distributions may provoke failure. More loci of possible initial failure occur when the gap is filled by a material that is different from the coating over the gap because there is an added interface.
