The solid portion refers to the percentage of the remaining dry resin and the pigment portion after the electrophoretic coating is heated at 105 ° C for 3 hours. The detection methods are generally as follows: Standard "GB/T1725-79 (89)" test methods equipment Porcelain crucible: 25ml Glass dryer with color-changing silicone Thermometer: 0-300 ° C Balance: the sensitivity is 0.01g Blasting oven Method steps: Weigh 2-4g of paint to the nearest 0.01g, then put it in a blast oven that has been heated to the specified temperature for a certain period of time, take it out and put it into a desiccator, cool it to room temperature, weigh it, then put it in After baking for a specified time in the oven at the specified temperature, after cooling to room temperature in a desiccator, weigh it (sampling more than 2 groups at the same time) Calculation: Solids = sample weight after baking / sample weight × 100% When measuring, the average value can be calculated by taking two to three parallel experiments.
