Curing effect enameled wire flexibility, solvent resistance, blow, soften the breakdown. Sometimes although at that time the performances, but film poor stability, the storage after period of time, performance data drop, even not qualified. If curing excessive, enameled wire film brittle, flexibility, thermal shock decline. Most enameled wires through the color of the paint film can judge curing degree, but because enameled wire is after many baking and become, only from appearance judgment is not comprehensive.

Each of the solidified film will be layered between enameled wire, can't form a strong overall, the strength of the paint film is poor, able to bear or endure blow performance not qualified. This is due to the paint film imines together after roasting full curing become molten material, plus its poor adhesion of the features, cause paint film statified phenomenon, doing blow when resistance test, the film will be a layer of a layer of scraping the broken. So get together to make the paint surface when baked imines basic curing but not fully, part of the molecules in the film there are a few of the yankees no reaction, when every paint baking was over, and finally to high temperature baking, make coating cured fully, form a firmer whole.
When enameled wires internal curing is not enough, but very sufficient external curing, enameled wire color is very good, but the detachment sex is very poor, the thermal aging test, may paint film casing or large peeling. Conversely, internal curing is better but external curing is insufficient, enameled wire color is very good, but able to bear or endure blow sex is very poor.
