Product details

introduction

Boasting years of collaboration with world-renowned sports equipment factories, GPC coatings introduces its two-component PU system primarily composed of hydroxypropyl acrylate resin. This guarantees superior physical properties, exceptional spray effects, and swift drying times. With a range of trendy colors, combined with pearlescent pigments and aluminum paste, our coatings enhance the aesthetic appeal and long-lasting protection for rackets, clubs, and other related sports equipment accessories.

Primer Coating

Our primer coat offers a steady base complemented by the decent wear-resistance attributes of polyurethane coating. For sports equipment like rackets that regularly experience impacts, our primer adds a protective layer that aids in enhancing its lifespan.

Colored Coating

Beyond offering a spectrum of vivid colors, our PU-colored coating also features a low VOC content, making it more environmentally friendly. It's not just about aesthetics; the chemical resistance of the coating ensures that your equipment remains unaffected by grease and sweat. Moreover, during those sweaty moments in a game, our unique formulation provides an enhanced grip.

Clear Coating

Our topcoat, formulated with precision, delivers an unparalleled luster, accentuating the intricacies of your sports equipment. Beyond its aesthetic brilliance, this advanced coating offers robust protection against environmental elements, such as UV radiation and precipitation, ensuring your equipment's integrity and performance remain uncompromised.

Physical Properties Test: PU coating for sports equipment

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	Test panels are placed horizontally and assessed with a Mitsubishi pencil hardness tester at 500g load. The topcoat registers a hardness of 2H, suitable for use as a basecoat.	No scratches
3	Film Thickness	Electronic coating thickness gauge	14±2um
4	Rub Resistance Test	Using an EF74 eraser under a 500g load, the coating is rubbed back and forth at a speed of 60 strokes/minute for 500 cycles. The substrate (paint) should not be exposed. (Test is specifically for topcoat)	No substrate exposure observed
5	RCA Test	Using a 175g load and tape, the coating is rubbed 50 times without exposing the substrate (paint). (Test is specifically for topcoat)	No substrate exposure observed
6	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. (Test is specifically for topcoat)	No substrate exposure observed
7	Chemical Resistance Test	Using a 100% cotton screen measuring 300x300mm and cycling at a rate of 0.5/S from a 3cm distance, a 500g load is applied for 100 cycles. Materials tested encompass ① Acidic artificial sweat (pH 4.7) ② Olive oil ③ Nivea ④ Lemon juice ⑤ Cleaner, and ⑥ 95% Isopropanol. Post-testing, the topcoat displayed no abnormalities. (Test is specifically for topcoat)	No substrate exposure observed
8	Boiling Water Resistance	It was submerged in an 80℃ water bath for 2 hours. The surface remains unchanged with a 5B pencil hardness test result.	No visible abnormalities, 5B hardness achieved.
9	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.
10	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.
11	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.
12	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.
13	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.
