The composition consists of zinc powder, epoxy resin and polyamide curing agent, etc..
The main characteristics of zinc powder has cathodic protection, excellent anti-rust performance, dry film 20 μm maintenance period of about nine months; Dry fast, only a short time can be moved, stacked and painted back road paint; It has good heat resistance and has a small burning area when welding and cutting. Excellent adhesion and impact resistance; Excellent wear resistance; Good oil resistance, water resistance and solvent resistance; The thickness of the paint film is within the specified range and does not affect the welding performance; Can be matched with most paint systems; Recognized by the China Classification Society.
The purpose is to use the pretreatment pipeline such as shipyard, heavy machinery factory, and steel structure factory as workshop primer, and the maintenance period is nine months.

Safety measures refer to the product safety technical specifications of Zhongsheng Paint(Ningbo) Co., Ltd..
Note that zinc rich primers can form zinc salts(ie, alkali zinc carbonate, also known as white rust) on the surface after prolonged exposure outdoors. They should not be exposed for a long period of time before painting. If the painting interval is longer, it is recommended to paint rust proof paint as soon as possible after the section is formed to reduce the amount of work of secondary rust removal; Zinc salt does not form on the surface of the paint film for several months in a clean indoor environment or within 14 days in a clean outdoor environment. However, in an industrial atmosphere or maritime climate, zinc salts will soon be produced, so the interval between painting and painting should be shortened as much as possible; In the surface with zinc salt, the cleaning grade sandblasting or mechanical rust removal method should be used for secondary rust removal, and all debris should be removed; When Jijieshigong is at high temperature, dry spraying is easy to occur. To prevent dry spraying, it must be diluted with a thinner until it is not dry
