G972 light gray two-component cathodic electrodeposition coating

1. Introduction: G972 light gray two-component cathodic electrodeposition coating of high solids and low solids pigment slurry consisting of modified epoxy resin, pigments, fillers, additives and other components. 2. Uses: Automotive and parts coatings. 3. Material: Steel and other metallic conductive material (using phosphate-treated steel sheets have better coating effect) 4. Features: pigment paste having the desired thixotropic, no precipitation. Two-component, construction convenient application. It has excellent storage stability and electrodeposition coating. It has a high throwing power. Free of lead and heavy metals, the Department of environmentally friendly products. Controllable electrodeposition coating film thickness. 5. Storage: Store in 5 ~ 30 ℃ away from fire cool and dry place, without open the original packaging shelf life of six months. 6. The original paint parameters: light gray pigment paste dope visual appearance fineness (μm) ≤15 GB / T1724-86 Non-volatile (%) 60 ± 2 GB / T6751-86 pigment to binder resin ratio 5:1 cauterization Appearance milky white liquid, non-hierarchical, non-precipitation visual non-volatile (%) 33 ± 2 GB / T6751-86 7. film properties: the appearance of smooth, smooth, no shrinkage allowing a slight orange peel visual pendulum hardness (s) ≥180 GB / T1730-93 Erichsen (mm) ≥5 GB / T9753-88 impact resistance 50 GB / T1732-93 Adhesion 0 GB / T9286-1998 L- effect 0K resistant to salt spray (h) ≥1000 / 2mm  ASTM B117 / 1997 8. construction method - with paint ratio: paste: Resin: water = 1:5 ~ 6:5 ~ 8 - with paint Method: Pour the electrodeposition bath calculation of half water, stirring was started adding resin, a pigment paste is added under stirring, and finally the remaining half of the water is added to the electrodeposition bath, stir pump cycle. - Electrodeposition bath preparation: Non-volatile matter (%) 19 ± 2 GB / T6751-86 pigment to binder ratio of 0.25 ± 0.05 9. Construction construction parameters voltage (V) 180 ~ 340 Temperature (℃) 28 ~ 32 PH 5.5 ~ 6.0 Conductivity (μS / cm) 1200 ± 400 HG / T3335-1997 (85) MEQ 25 ~ 30 Drying condition (℃ / min) 165 ~ 180/20  GB / T1728-89 film thickness (μm) 15 ~ 30 GB / T1764-89 throwing power (cm) ≥20 Ford case law rupture voltage (V) ≥350 10. Note: with bath with deionized water quality conductivity ≤10μS / cm. The construction process must be carefully read product specification before using this coating, in accordance with its requirements for operation.
