Product details

introduction

Building on years of collaboration with world-renowned home appliance manufacturers, GPC Coatings introduces a two-component polyurethane system, primarily based on hydroxypropyl acrylate resin. This guarantees superior physical performance, impeccable spray efficiency, and rapid drying times. Our coatings not only offer fundamental colors typically seen in home appliances but also bring forth a diverse palette to meet various aesthetic preferences, providing enhanced visual appeal and lasting protection for a wide range of household devices.

Let your appliances stand out in any environment, be it refrigerators, air conditioners, ovens, or washing machines. Our polyurethane coatings excel in both protection and decoration.

Primer Coating

Our polyurethane primer is tailored to give superior adhesion and protection for home appliances. It lays a sturdy foundation for the top layers, ensuring long-lasting appearance and performance.

Colored Coating

Choose our color coat range to achieve finishes from high-gloss to matte. Beyond excellent resistance to wear, scratches, and chemicals, our coatings ensure durability and cater to contemporary personalized color trends.

Clear Coating

Our top coat not only provides an additional layer of protection but also enhances UV resistance, warding off the damages from sunlight, particularly suitable for outdoor home appliances.

Physical Properties Test: PU Coating for Home Appliances

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.
