Iron oxides Use in High-temperature-cured Coatings

Iron oxides

Standard yellow iron oxides are the ideal inorganic pigments to develop a wide range of color shades due to the advantages in performance and cost provided by their high hiding power and opacity, excellent weather, light and chemical fastness, and reduced price. But their use in high-temperature-cured coatings such as coil coating, powder coatings or stoving paints is limited. Why? When yellow iron oxides are submitted to high temperatures, their goethite structure (FeOOH) dehydrates and partially turns into hematite (Fe2O3),Read More …

Glycidyl Methacrylate GMA- TGIC Replacement Chemistries

Glycidyl Methacrylate GMA- TGIC Replacement Chemistries Acrylic graft copolymers containing free glycidyl groups

Glycidyl Methacrylate GMA- TGIC Replacement Chemistries Acrylic graft copolymers containing free glycidyl groups These hardeners,which include glycidyl methacrylate(GMA) curatives have recently been promoted as crosslinkers for carboxy polyester. Since the cure mechanism is an addition reaction, film builds that exceed 3 mils(75 um) are possible. So far, accelerated weathering tests of polyester GMA combinations indicate results similar to those of TGIC. Some formulating problems exist when acrylic graft copolymers are used ,for example, flow and leveling properties are relatively poor.Read More …

Tetramethoxymethyl glycoluril (TMMGU)

Tetramethoxymethyl glycoluril (TMMGU), TGIC Replacement Chemistries Hydroxyl polyester/TMMGU combinations,such as powderlink 1174,developed by Cytec, may offer an excellent opportunity to replace TGIC in applications that require thinner film builds. As this chemistry’s cure mechanism is a condensation reaction, some of the application problems described in the section on HAA curatives also occur with this curative. However, recent evaluations and data show that pin hole free coatings can be obtained with hydroxyl polyester / TMMGU combinations even when film builds exceedRead More …

Plasticizers in Coating Formulations

Plasticizers in Coating Formulations

Plasticizers are used to control the film formation process of coatings based on physically drying film forming materials. Proper film formation is essential in order to meet demands on specific coating properties such as dry film appearance, substrate adhesion, elasticity, in combination with high level of hardness at the same time Plasticizers function by reducing film formation temperature and elasticize the coating; plasticizers work by embedding themselves between the chains of polymers, spacing them apart (increasing the “free volume”), andRead More …

Color Fading in the coatings

Gradual changes in color or fading are primarily due to the color pigments used in the coating. Lighter coatings typically are formulated with inorganic pigments.These inorganic pigments tend to be duller and weaker in tinting strength but are very stable and not easily broken down by exposure to UV light. To achieve darker colors, it is sometimes necessary to formulate with organic pigments. In some instances, these pigments may be susceptible to UV light degradation. If a certain organic pigmentRead More …

Pearlescent Pigments

Pearlescent Pigments

Pearlescent Pigments Traditional pearlescent pigments consist of a high-refractive-index metal oxide layer coated onto a transparent, low-refractive-index substrate such as natural mica. This layering structure interacts with light to produce constructive and destructive interference patterns in both the reflected and transmitted light, which we see as color. This technology has been extended to other synthetic substrates such as glass, alumina, silica and synthetic mica. Various effects range from satin and pearl luster, to sparkle with high chromatic values, and hue-shiftingRead More …

Catalysts are used to improve abrasion resistance of coatings

Catalysts are used to improve abrasion resistance of coatings

General strategies of increasing crosslink density by use of higher-functionality oligomers and/or larger amounts of crosslinking agents have been used to improve abrasion resistance. To get the higher crosslink density, catalysts are sometimes added to the paint formulation as additives in small quantities. Catalysts are additives that will increase the rate of a -chemical reaction but are not consumed or changed in the reaction process. Catalysts have widely varying compositions that depend on the nature of the reaction being catalyzed.Read More …
