1235 aluminum foil 6 micron surface attached to the oil generally can not be completely removed, and the surface folds are not flat on the surface tension will have a great impact on the direct measurement of the contact angle is unrealistic, the production practice is used more to reflect the wetting ability of the dyne value, the higher the value of the dyne, the better the wetting performance.

Surface wetting tension is one of the most important technical indicators of 1235 aluminum foil 6 micron, which affects the adhesive quality of the coating, especially affecting the firmness of the coated carbon foil coating, the reason for the low value is that the aluminum foil does not bond well with the adhesive material, and there are defects such as leakage of the coating.
1235 aluminum foil 6 micron has a surface causality value of >32dyn/mm, and the wetting performance is more and more superior for some carbon coated foils with higher requirements. 1235 Aluminum foil 6 micron should have a surface factorization value > 32dyn/mm, and even 34dyn/mm for some demanding carbon coated products.
