The surrounding climate plays a critical role in dictating the required time for electrostatic powder layers to fully polymerize. Powder coating is a non-liquid coating method that requires elevated temperatures to fuse and crosslink the powder particles into a smooth protective coating. When the room temperature surrounding the curing unit or Tehran Poshesh workpiece is critically cool, the layer may struggle to achieve uniform thermal penetration, leading to extended cure times or partial crosslinking. This can result in weak bonding, loss of luster, and reduced durability such as shock tolerance and bendability.

On the flip side, when ambient temperatures are too high, particularly in production halls without climate control, the the outer layer of the finished items may begin to soften or sag before the heating cycle begins.
