Product details

introduction

Our company is a leading manufacturer specializing in a variety of computer peripherals, household appliances, automotive interior components, and dedicated coatings. We develop high-temperature baking paints tailored to diverse substrates. All our products are compliant with the EU ROHS standards and have passed the rigorous SGS tests, highlighting both their technological sophistication and environmentally friendly nature.

Here's what we offer

● Magnesium-Aluminum Alloy Specific Primer: Formulated with a high solid composition, our specialized primer effectively targets and mends pinholes in magnesium-aluminum alloy materials. Paired with our array of colored coating, it accentuates the aesthetic allure of your products, guaranteeing excellent adhesion and adaptability for multiple touch-ups. Choose this primer for a heightened blend of elegance and longevity in your finishes.

● High-Temperature Baking Coating: Designed specifically for a variety of metal materials, including magnesium-aluminum alloy, zinc alloy, and aluminum alloy, our line of primers and colored coatings are optimized for exceptional adhesion, outstanding coverage, high-temperature resistance, stable physical and chemical properties, and the ability for multiple touch-ups. Based on our solution, achieve a superior and enduring finish.

Product Specification : Special Metal (AC) Coating

Product Specifications	Main Component: AC System	Thinner: Lacquer Thinner

Physical Properties Test: Special Metal (AC) Coating

Test Items		Test Conditions	Test Results
1	Adhesion	The sample is placed flat and scored both horizontally and vertically using a 100-grid knife. After cleaning the scored section, 3M#610 tape is applied over the grid. The tape is then pulled off at a 45° angle three times, resulting in a 5B adhesion rating.	5B
2	Hardness	Lay the test panel flat. Using the Mitsubishi Pencil Hardness Tester at a 500g load, the coating should exhibit a scratch-free surface with a hardness rating between H-2H.	No scratches
3	Film Thickness	Determined by film thickness gauge to be 20±5um (single coat)	20±5um
4	Flexibility	≤ 2mm without cracks	no cracks
5	Impact Test	Φ1/2×500g×30cm No paint detachment	No paint detachment
6	Abrasion Resistance Test	Test Procedure: Employing an EF74 rubber with a 500g load, the coating underwent 500 abrasion cycles. Requirement: The underlying material should not be exposed.	No substrate exposure observed
7	Alcohol Resistance Test	Rubbing Material: Cloth saturated with 99.5% alcohol. Load: 500g. Rubbing Distance: 3cm per cycle. Frequency: 30 cycles per minute. Criteria: The coating should exhibit no exposure of the underlying material (paint) after more than 500 cycles.	No substrate exposure observed
8	QUV Resistance	Tested with QUV test for over 120 hours without fading; gloss reduction rate < 25%.	Loss of gloss < 25% ΔE < 3.0
9	Water Resistance	Immersed in pure water at 40±2℃ for 240 hours. After a 1-hour standing period post-immersion, the coating remains free from significant softening, discoloration, bubbling, or reduced adhesion.	Appearance unchanged; 5B adhesion.
10	Corrosion Resistance	Tested at 35℃ with 95% humidity using a 5% NaCl solution spray, the product showed no rust or discoloration on its surface after 480 hours in the salt spray environment.	Single-sided corrosion <2mm Adhesion meets standards.
11	Humidity Resistance Test	After testing at 65°C and 90% humidity for 120 hours, all properties remain unchanged.	Appearance unchanged; 5B adhesion.
12	Thermal Cycling Resistance	The test cycles through temperatures of -40℃ for 1.5 hours, then 25℃ for 0.5 hours, followed by 65℃ at 90% RH for 1.5 hours, and this sequence is repeated for a total of 20 cycles.	Appearance unchanged; 5B adhesion.
13	Cosmetic Resistance	Test Method: The sample's coating was applied with NIVEA hand cream and left at room temperature for 24 hours. Result: No noticeable changes were observed in its	Appearance unchanged; 5B adhesion.
14	Artificial Sweat Resistance	Upon introducing a droplet of synthetic sweat (pH 4.7) onto the specimen surface, it was maintained under ambient conditions for a duration of 24 hours. Following the interval, the sample's exterior was meticulously examined for any visual alterations.	Appearance unchanged; 5B adhesion.
