As automotive coatings have performance requirements such as high weather resistance, high corrosion resistance, high wear resistance, heat resistance, gloss retention and color retention, technological progress is relatively slow.
The initial application of powder coatings was limited to automotive parts, automotive primers, etc., and later gradually used for automotive underside powder coatings and powder finish varnishes, becoming the true automotive powder coatings. Today we first introduce MST® Automobile engine powder coating Quotation.
MST® Automobile engine powder coating Quotation mainly selects epoxy powder coatings with good high temperature resistance, heat resistance, impact resistance and flexibility.
The MST® Automobile engine powder coating Quotation produced by Milestone is epoxy powder coating. This automobile engine powder coating can be directly applied to the surface of cast iron engine body after sandblasting and rust removal. The curing condition of Automobile engine powder coating Quotation is 140℃/(15~25)min.
MST® Automobile engine powder coating Quotation can resist the thermal shock caused by the high temperature of the engine during continuous operation, and can also meet the performance requirements of the automobile engine under extreme conditions (such as high-speed machining) without chipping, curling or peripheral fins.
Automobile manufacturers' performance requirements for powder coating for automobile engines:
Film color and appearance: The surface of the paint film is flat, allowing slight orange peel
Film thickness/μm: 80--120
Salt spray test 120h body: no peeling, no blistering
Adhesion/level: 0 or 1
High humidity test: No blistering, peeling, softening, etc. on the surface of the paint film, and slight discoloration is allowed.
