Product details

introduction

Our water-based, self-drying coating, crafted specifically for vehicle axle castings and key automotive components such as axle beams, chassis parts, and e-vehicle battery carriers, champions eco-friendliness and efficiency. It is tailored for large items that can't be cured by traditional baking, ensuring rapid air drying in 10-30 minutes without the need for extra energy or drying machinery.

Here's what we offer

●Primer Coating:

Our primer establishes a sturdy foundation for axle castings. Whether it's aluminum, primed surfaces, or

galvanized components, it intensifies the adhesive strength of the coating, ensuring a seamless bond

with the casting, paving the way for subsequent layers.

● Colored Coating:

Our colored paint offers a diverse range of colors and gloss options. Beyond maintaining the original

aesthetic appeal of the axle castings, it boosts market attraction. Its distinctive weather resistance

ensures the product maintains its fresh appearance for an extended period.

●Clear Coating:

This transparent coating shields against corrosive agents and withstands challenges like stone chipping.

It also bolsters impact and abrasion resistance, ensuring durability.

Physical Properties Test: : Water-based self-drying coating for vehicle axle castings

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	Sharpen a Mitsubishi H-grade pencil on sandpaper. Apply 500g weight and glide at a 45° angle from F to H. Ensure no scratches	F-H No scratches
3	Film Thickness	Electronic coating thickness gauge	10±2um
4	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 200cycles.	No substrate exposure observed
5	High Temperature and Humidity Resistance	Exposed to 65℃ and 95% humidity for 120 hours, followed by a 6-hour recovery at room temperature. Post-examination shows no abnormalities with a 5B pencil hardness test result.	No visible abnormalities, 5B hardness achieved.
6	High Temperature Storage	Stored in a 70℃ environment for 48 hours, then allowed 4 hours to return to room temperature. Post-examination shows no abnormalities with a 5B pencil hardness test result.	No visible abnormalities, 5B hardness achieved.
7	Low Temperature Storage	Placed in a -40℃ environment for 48 hours, followed by a 4-hour recovery at room temperature. Post-examination shows no abnormalities with a 5B pencil hardness test result.	No visible abnormalities, 5B hardness achieved.
8	Thermal Shock Resistance	Alternated between 80℃ and -40℃, each temperature held for 1.5 hours with a 20-minute transition time, for a total of 20 cycles. Allowed 4 hours of recovery at room temperature. The surface should show no discoloration, blistering, peeling, shedding, or gloss variance.	No visible abnormalities, 5B hardness achieved.
9	Temperature and Humidity Cycling	Alternated between 65℃ at 95% humidity and -40℃, each condition held for 1.5 hours with a 20-minute transition time, for a total of 20 cycles. Allowed 4 hours of recovery at room temperature. The surface should show no discoloration, blistering, peeling, shedding, or gloss variance.	No visible abnormalities, 5B hardness achieved.
