Application studies in 50 VOC gloss paints / Greg Monaghan in COATINGS TECH, Vol. 4, N° 10 (10/2007)  

[article]  inCOATINGS TECH > Vol. 4, N° 10 (10/2007) . - p. 30-39 Titre : Application studies in 50 VOC gloss paints Type de document : texte imprimé Auteurs : Greg Monaghan, Auteur Année de publication : 2007 Article en page(s) : p. 30-39 Note générale : Bibliogr. Langues : Américain (ame) Résumé : Gloss paints which have been formulated to meet the 50 gram/liter regulations may require new formulation and application techniques to optimize appearance. Many Coatings manufacturers are concerned that painting techniques which have been used with higher VOC aqueous or solvent paints may give poor appearance in these low-VOC paints, especially in the areas of brushed flow and open time. A study has been conducted to determine the optimum rheology, formulation space, and painting techniques to use in applying 50 VOC gloss paints. Suggestions for 50 VOC high gloss formulations with improved application properties and slight modifications of several common application techniques are presented in this article. Together, these techniques can give excellent professional quality finishes in VOC-compliant gloss paints.

Cationic stain blocking primer technology / Greg Monaghan in COATINGS TECH, Vol. 16, N° 5 (05/2019)  

[article]  inCOATINGS TECH > Vol. 16, N° 5 (05/2019) . - p. 26-33 Titre : Cationic stain blocking primer technology Type de document : texte imprimé Auteurs : Greg Monaghan, Auteur ; Alex Pinnix, Auteur Année de publication : 2019 Article en page(s) : p. 26-33 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Cations Chlorure de polyvinyle Epoxydes Essais (technologie) Formulation (Génie chimique) Polyacryliques Primaire (revêtement) Résistance aux taches Revêtements en bâtiment Revêtements en phase aqueuse Index. décimale : 667.9 Revêtements et enduits Résumé : Most water-based architectural stain blocking primers typically have only moderate stain blocking performance, and they are designed to lock stains in the primer coat rather than block stains. This leads to a major performance difference compared to solvent-based primers. Since the stain is visible in the dry film when a bleeding substrate is coated with water-based primer, the painter cannot tell with any degree of certainty if the stain will migrate into the topcoat. Novel cationic water-based primers offer far superior stain blocking and are like solvent-based primers because many stains are blocked by the primer coat rather than locked into the primer coat. For these cationic primers, however, manufacturing procedures and raw materials are different from those typically used in conventional anionic architectural coatings.

Formulating 50 VOC gloss floor paints / Greg Monaghan in COATINGS TECH, Vol. 6, N° 3 (03/2009)  

[article]  inCOATINGS TECH > Vol. 6, N° 3 (03/2009) . - p. 34-41 Titre : Formulating 50 VOC gloss floor paints Type de document : texte imprimé Auteurs : Greg Monaghan, Auteur Année de publication : 2009 Article en page(s) : p. 34-41 Note générale : Appendice - Bibliogr. Langues : Américain (ame) Catégories : Composés organiques volatils Résistance des matériaux Revêtements:Peinture Sols -- Conservation Sols -- Revêtements protecteurs Index. décimale : 667.6 Peintures Résumé : South Coast Air Quality District (SCAQMD) requirements that gloss floor paints contain no more than 50 g/L volatile organic compounds (VOC) means that solvent-based urethane alkyds and 200 VOC latex gloss floor paints will need to be reformulated for sale in the Los Angeles area. Although there are now many binders offered for 50 VOC gloss trim paints, gloss floor paints require a different balance of properties. Of particular importance is that the paint should coalesce at low cosolvent levels but still be hard enough that it does not pick up dirt or scuff easily under foot traffic. A novel accelerated wear testing machine was used to screen binder chemistries for gloss floor paints. A 50 VOC paint based on a combination of a water-based ambient temperature crosslinking polymer with a water-dispersible oil-modified urethane has been found to give performance equal to commercial solvent-based urethane alkyds and commercial 200 FOC water-based gloss floor paints.

Solid color deck stains : Trends, substracts, and formulation study / Greg Monaghan in COATINGS TECH, Vol. 4, N° 7 (07/2007)  

[article]  inCOATINGS TECH > Vol. 4, N° 7 (07/2007) . - p. 30-35 Titre : Solid color deck stains : Trends, substracts, and formulation study Type de document : texte imprimé Auteurs : Greg Monaghan, Auteur Année de publication : 2007 Article en page(s) : p. 30-35 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 667.9 Revêtements et enduits Résumé : The changing decking market offers new products to consumers and new challenges to coatings manufacturers. The voluntary phase out of CCA-treated wood for residential applications at the end of 2003 opened up the decking market to new wood treatments as well as composite decking materials usually composed of wood fibers and recycled plastics. Solid color stains which are used to coat these substrates need good adhesion on weathered and unweathered composite substrates, abrasion resistance, stainblocking, and exterior durability. In addition, government regulations are forcing solid color stains to have lower VOC levels and many stains are now formulated from bases with high loadings of universal colorant. Background information on new decking substrates will be presented in this article along with data from an evaluation of acrylic binders in VOC-compliant solid color stain formulations for these substrates.
