What causes things not to dry when the temperature drops? Thinner switching.
Despite having the same conditions as summer, the drying is poor. This explains how to review solvent selection and curing time during temperature drops.
Even though I painted under the same conditions as in summer, the drying has become poor. What has changed is not the paint, but the temperature. ────────────── ■Cause of Occurrence The evaporation rate of thinner varies greatly with temperature. Using slow-drying thinner intended for summer in the autumn and beyond prevents the solvent from fully evaporating. ■The Truth When the temperature drops by 10 degrees, the evaporation time of the solvent roughly doubles. The remaining solvent escapes from the inside during curing, creating voids and pinholes. The surface may dry, but the interior remains uncured, leading to issues in the next process. ■Improvement Measures Determine and display the brand and dilution ratio of thinner for each temperature range. Ensure adequate setting time and fully remove the solvent before curing. Please utilize the seasonal thinner selection chart.
