When you pour the dosa batter on a non-stick pan, the flour is sticky. But you can easily take out the dosa from the pan with a wooden spatula once it’s cooked. You don’t have to smear the pan with oil like the traditional ones. Wonder why? This would not be possible if not for the Teflon coating in the pans.
Teflon does not melt easily. It has a high melting point and is also stable at very low temperatures. Teflon is extremely resistant to corrosion. It cannot be dissolved by most of the materials. In addition to this, it is very slippery and has high resistance corrosive chemicals. Therefore, Teflon provides a perfect coating material for cooking utensils that resists heat, friction and wear and tear. Teflon is also used widely in carpets, wall coverings, paints and as weatherproofing on outdoor signs.
