In fact, these two kinds of coatings are very different, from their performance requirements, the use of the environment, formula design and other aspects to do comparative analysis.

(I) food safety aspects

used in industrial molds, in this regard is relatively loose, can use the raw materials of the elasticity is relatively large.

(II)

what is the second recoating? is to spray the old coating on the surface, after a little polishing can be re sprayed with a new layer of coating.

Teflon coating has good non-tackiness. It is very difficult to spray a new layer of coating on its surface. PFA is generally used in mold Teflon, which is non-tacky and can be recoated.

used in kitchen utensils and tableware, there is generally no need to consider the problem of secondary recoating, because these workpieces are not big, even if the spray is not good or scratch coating, the cost of rework is not high, and the secondary recoating will have obvious color unevenness, which is unacceptable for consumer goods for civilian use.

(III) corrosion protection

Teflon, which is used in kitchenware and tableware, is different. We need to make great efforts in anti-corrosion. Take the pan as an example. When cooking, we need to resist high temperature, and in high temperature environment, we also need to prevent salt water, acetic acid, hot oil, sugar and other corrosion. In the process of use, some people wash the dishes immediately after frying, and also take into account the ability of the coating to withstand sudden cold and heat. These are very demanding requirements. Therefore, the consideration of anti-corrosion on kitchenware and tableware is the first priority.
