Product details

introduction

As electronics continually evolve in sophistication, GPC coatings focuses on delivering two-component PU coatings that meet the stringent specifications of electronic products. Powered by hydroxypropyl acrylate resin technology, our coatings set a new benchmark for physical testing standards in the electronics sector while promising exceptional application and rapid drying.

Primer Coating

Our polyurethane primer offers robust adhesion suitable for plastics, metals, and fiberglass. Moreover, its superior insulating properties ensure device safety. insulating properties.

Colored Coating

Dive into a world of aesthetic brilliance with our colored coating, tailored for electronic devices. This range offers finishes from lustrous high-gloss to understated matte. Beyond the allure, the durability it imparts to everyday gadgets like smartphones and laptops against wear is unparalleled. Its hues also keep pace with the latest fashion trends.

Clear Coating

Protection meets sustainability in our clear top coat crafted for electronic devices. It offers a formidable shield against chemicals, UV rays, and moisture. And in an era conscious of its carbon footprint, our coatings champion eco-friendliness with low VOCs and non-toxicity.

Physical Properties Test: PU Coating for Electronic Products

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.
