The modified epoxy resin Beckopox EM 460 is recommended in combination with the standard polyvinylbutyral 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. The formulation can also be used as a one-component system. In this case, Part B is premixed and subsequently added to part A after dispersion. 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 microns by bar coater. The formulation was also tested with a 40 micron acrylic/isocyanate top coat. 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.

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 | |

Acronal S760 is a self cross-linking styrene-acrylic dispersion which can be cured at room temperature by the addition of acid catalysts. Pre-neutralisation of Cycat 500 and phosphoric acid with AMP 95 and ammonia is necessary to ensure paint stability. The addition of AMP 95 also helps to heat stabilise the paint during milling. Higher PVC-values reduce the salt spray performance, and values around 20 to 30 vol.-% are suggested. Alternative fillers such as talcs, calcium carbonates (Millicarb B from Omya) or dolomites (Microdol extra from Norwegian Talcs) or combinations thereof can be used satisfactorily. view less | |

Haloflex 202 is a water thinnable vinyl-acrylic dispersion with an acidic pH. The addition of Alcophor 827 is beneficial in two respects: the pH is stabilised at 6.5 which would otherwise be buffered by SHIELDEX® anti-corrosive pigments, and it also improves the corrosion resistanceafter hot salt spray and humidity exposure. The addition level of SHIELDEX® anti-corrosive pigments should not exceed 3 wt.-% to ensure that the pH of the final formulation does not exceed 7. view less | |
