Answer:
The substance used in coating for making non-sticky utensils is Teflon. Here is a detailed explanation:
Teflon:
Teflon is a brand name for a type of non-stick coating made from a synthetic polymer called polytetrafluoroethylene (PTFE). It is known for its non-stick properties and is commonly used in cookware and kitchen utensils. Here are some key points about Teflon:
1. Non-stick properties: Teflon has a very low coefficient of friction, which means that it reduces the adhesion of food to the utensil's surface. This makes it easier to cook and clean, as food residues are less likely to stick to the utensil.
2. Heat resistance: Teflon is highly heat resistant, with a melting point of around 327 degrees Celsius (620 degrees Fahrenheit). This makes it suitable for use in cooking utensils, as it can withstand high temperatures without degrading or releasing harmful fumes.
3. Chemical resistance: Teflon is resistant to many chemicals, including acids and bases. This makes it durable and long-lasting, as it can withstand exposure to various substances without corroding or degrading.
4. Easy to clean: Due to its non-stick properties, Teflon-coated utensils are easy to clean. Food residues can be easily wiped off, and the utensils can be washed with mild soap and water.
5. Wide range of applications: Apart from cookware and utensils, Teflon is also used in various other applications, such as electrical insulation, automotive parts, and industrial coatings.
In conclusion, Teflon is the substance used in coating for making non-sticky utensils. Its non-stick properties, heat resistance, chemical resistance, and ease of cleaning make it a popular choice for cookware and kitchen utensils.
