What is high-temperature curing of steel lined PTFE spray coating

Steel lined PTFE spray coating is a unique high-performance coating that combines heat resistance, chemical inertness, excellent insulation stability, and low friction, with comprehensive advantages that other coatings cannot compete with. Its flexibility in application allows it to be used on almost all shapes and sizes of products. Next, the editor will introduce the high-temperature curing process of PTFE spraying on steel lining.

The high-temperature curing process of PTFE spraying on steel lining is the key process for the quality of PTFE coating. If the curing depth of the coating is not sufficient, the bonding strength of the coating will be low, and the coating is prone to cracking and peeling; If the curing depth of the coating is too deep, the coating is prone to aging, cracking, peeling, and sintering, which can cause shrinkage corrosion in the mold and make the surface very rough, leading to mold scrap. The curing speed is too fast, causing premature shrinkage of the coating surface, resulting in closed cell structure, high capillary pressure, and ultimately leading to coating rupture. Therefore, the curing temperature, curing time, and curing speed of the coating play a decisive role in the quality of the coating.

After the baking of the steel lined PTFE spray mold is completed, the speed of cooling also has a certain impact on the service life of the coating. Because the shrinkage of the coating and the mold substrate is different, the slow cooling effect of the mold in the oven together with the oven is better.
