Mechanical Properties of Coatings

Coatings should all have certain mechanical properties. Mechanical properties include hardness, impact strength and flexibility. The hardness, impact strength and flexibility of coatings can only be truly reflected after an actually dry and firm coating is formed on the surface of the product. Hardness is expressed as a pendulum of a certain quality, the "ratio" of the attenuation event at the specified oscillation amplitude (eg ≥ 0.5), the impact strength is expressed in Mpa (or kgf/cm ²), and the flexibility is expressed in "mm". Coatings should be selected according to the quality requirements of the product coating on the mechanical properties of the coating. The hardness ratio is large, the impact strength is 5MPa, and the flexibility is within 1mm, which is basically a coating variety with good mechanical properties.
