What does a 115° water droplet Angle mean?

A: The water droplet Angle is an indicator to measure the water and oil repellency performance of the oleophobic layer. The larger the Angle, the better the anti-fingerprint effect and the smoother the hand feel. The 115° water drop Angle of Guanfudun is the self-test data of the Woowhead brand laboratory under the standard test environment. It is not easy to accumulate fingerprints or oil stains during daily use, and the touch sliding is smooth. In contrast, the water droplet Angle of the hydrophobic layer of a common membrane is approximately 100°-110°, while that of the non-hydrophobic layer is about 30°-60°. The oleophobic layer is a consumable. The Guanfudun wear-resistant reciprocating cycle is 10,000 times (tested by the brand laboratory), and the durability of the oleophobic layer is better than that of ordinary films (about 3,000 times). It is recommended to dry clean with a microfiber cloth and avoid frequent wiping with alcohol (which will accelerate the wear of the oleophobic layer).
