Performance Specifications of Epoxy Coating

Item	Test Method	Performance Specification
Pinholes	GB/T 34202. BS EN 14901	No leakage points
Pull-off Adhesion (MPa)	BS EN 14901. GB/T 34202	Average >20. Minimum ≥6
Impact Resistance 3J, 15.9mm Punch or 5J, 25mm Punch	BS EN 14901. GB/T 34202	No leakage points
Indentation Resistance 1mm Diameter Indenter, 70℃, 10MPa	BS EN 14901. GB/T 34202	48h, indentation depth ≤30% of coating thickness; increase in depth from 24~48h is less than the increase from 0~24h, and does not exceed 5% of the original coating thickness
Chemical Corrosion Resistance	BS EN 14901. GB/T 34202	No change in coating
Crosslinking MIBK Rub Test	BS EN 14901. GB/T 34202	Consistent with the sample plate provided by the powder manufacturer
△Tg (℃)	BS EN 14901. GB/T 34202	-3≤△Tg≤3

Note:

The MIBK rub test is a simple method for evaluating the curing condition and does not mean that the coating is qualified only when there is absolutely no color fading. According to the requirements of GB/T 34202 and BS EN 14901. the coated workpiece is compared with the fully cured sample provided by the supplier under the same rubbing conditions. If the results are consistent, it indicates that there is no curing problem. If there is any dispute regarding the result, final evaluation can be performed through thermal property testing and △Tg measurement.
