PPG Whitford coated stainless steel woks are high-temperature resistant primarily because of the combination of the stainless steel material and the special non-stick coating. Here's how this resistance is achieved:
Stainless Steel Material: Stainless steel is known for its excellent heat resistance properties. It can withstand high temperatures without warping, discoloration, or other forms of structural damage. This material is often used in cookware because it maintains its shape and integrity even when exposed to intense heat.
Non-Stick Coating: PPG Whitford coatings are designed to be high-temperature resistant. They are engineered to withstand the elevated temperatures typically used in cooking, such as stir-frying or searing. These coatings are formulated to remain stable and not break down at high temperatures.
PFOA and PTFE-Free Formulations: Many PPG Whitford coatings are formulated without perfluorooctanoic acid (PFOA) and polytetrafluoroethylene (PTFE), which are chemicals that can release harmful fumes at high temperatures. By excluding these substances, the coatings are safer for high-temperature cooking.
Heat Distribution: Stainless steel woks are known for their even heat distribution. This property helps in preventing hot spots and allows for consistent cooking at high temperatures without the risk of burning or uneven cooking.
Oven Safe: Many PPG Whitford coated stainless steel woks are designed to be oven-safe, allowing you to transfer them directly from the stovetop to the oven for recipes that require baking or broiling at high temperatures.
It's important to note that while PPG Whitford coatings are engineered to be high-temperature resistant, there are limits to their heat resistance. Excessive heat, such as cooking on the highest burner setting for an extended period or allowing the wok to become empty and overheated, can still potentially damage the coating over time. Therefore, it's advisable to follow the manufacturer's guidelines for temperature usage and care instructions to ensure the longevity of your PPG Whitford coated stainless steel wok.
