Formulation For Lithol Rubine Dispersion Using Esperse 506 (Formulation #1) Ethox Chemicals Formulation For Lithol Rubine Dispersion Using Esperse 506 (Formulation #1).

Traditionally, lithol rubine and other metallized azo red aqueous dispersions have a tendency to be unstable due to free metallic cation content of the pigment. Some improvements in formulation have been made with the introduction of HPD 296 dispersing resin from Johnson Polymer. Though the pigments have more stability in this grind resin, some degree of pseudoplastic character still exists in the dispersions and inks made from it. The addition of a small amount of Esperse 506 to the formula dramatically reduces the pseudoplastic tendencies while maintaining viscosity and color stability. view less

Epikote 1007 and Epikote 1009 are standard epoxy resins used in coil coating primer applications. UFR 80 is a typical urea based crosslinker used in these applications. The cure response within this formulation was controlled by the use of Epoxy blocked Phosphoric acid (co-catalyst) and Halox 650 (dicarboxylic-acid co-catalyst). These components prevent the interaction of SHIELDEX® anti-corrosive pigment with the acid catalysts and any acid funtionality on the resin systems, thus ensuring maximum cure response. The SHIELDEX® C 303 anti-corrosive pigment containing epoxy coil primer was applied on Bonder 1303 (ex Chemetall) and Granodine C 108 (ex Henkel) treated galvanised steel test panels. The primer was applied by bar coater to a dry film thickness of 5 – 7 microns. Cure was to a peak metal temperature (PMT) of 216 – 224 °C. A polyester-melamine topcoat was applied to a bar coated dry film thickness of 20 – 25 microns and cured to a PMT of 232 – 241 °C. view less

Beckopox EM 460 together with Phenodur PR 263 is recommended in combination with the standard resin Mowital B 30 H to ensure good wet adhesion properties. Silquest A 187 Silane promotes wet adhesion properties especially on galvanised steel and aluminium substrates. The combination of Alcophor 827 with SHIELDEX® anti-corrosive pigments improves hot salt spray resistance over steel substrates. After mixing the two components and letting these prereact for a minimum of 30 minutes, the formulation was tested on solvent degreased cold rolled steel, galvanised steel and aluminium substrates applied to a dry film thickness of 10 –15 μm by bar coater. The formulation was also tested with a 40 micron acrylic/isocyanate top coat. Drying was for 7 days at ambient conditions. view less

Dynapol L205 and Dynapol L208 are high molecular weight polyester resins widely used in coil coating primer applications for both building and domestic appliance applications. Cymel 350 is a typical melamine based crosslinker. The cure reponse within this formulation was controlled by the use of Silane A187 (Silane Ester), Epoxy blocked Phosphoric acid (co-catalyst), EDBSA (sulphonic acid co-catalyst) and Halox 650 (Dicarboxylic acid). These components prevent the interaction of SHIELDEX® anti-corrosive pigments with the acid catalysts and any acidic functionality on the resins, thus ensuring maximum cure response. view less
