Water-based epoxy orange grain topcoat: Add unique texture charm to the space
Jun 05, 2025
Water-based epoxy orange grain topcoat has a place in the coating market with its unique decorative effect and practical performance. Environmental protection properties
Safe and harmless: Using water as a solvent, it does not contain any harmful organic solvents, which eliminates the harm of volatile organic compounds to human health and the environment from the root. When furniture manufacturers use this paint to paint the surface of furniture, workers do not need to worry about pungent odors and harmful gases inhaled during the production process, which ensures occupational health; finished furniture will not release harmful substances after entering the home, creating a safe living environment for consumers.
Compliance with environmental regulations: It has passed a number of strict environmental certifications, such as the China Environmental Labeling Product Certification, etc. Whether in the domestic or international market, it meets various environmental regulations and provides strong support for the company's products to enter the market.
Performance highlights
Unique decorative effect: It can form a concave and convex texture similar to the surface of orange peel. This unique orange grain effect brings rich layering and three-dimensionality to the surface of objects. In the coating of metal columns in the hotel lobby, the orange grain topcoat makes the originally monotonous metal surface artistic and enhances the style of the entire space; in the coating of equipment shells, the orange grain effect is not only beautiful, but also can effectively cover up the minor defects generated during the production process and improve the appearance quality of the product.
Good physical properties: It has excellent wear resistance and impact resistance. The concave and convex texture structure can disperse external forces. In daily use, even if it is slightly bumped or rubbed, the coating is not easily damaged. For example, after the outdoor billboard frame is coated with orange grain topcoat, it can still keep the coating intact in harsh environments such as wind, sun, sand and dust, and extend the service life of the billboard. At the same time, its corrosion resistance is also very excellent, and it can adapt to complex environments such as humidity, acid and alkali, and is suitable for surface protection of chemical equipment, coastal facilities, etc.
Key construction
Substrate pretreatment: Thoroughly clean the substrate before construction to remove impurities such as oil, rust, and dust. For metal substrates, sandblasting or shot blasting can be used to improve surface roughness and enhance coating adhesion; for wooden substrates, grinding and gap filling are required to ensure a smooth surface.
Spraying process control: Spraying is used for construction. By adjusting the caliber of the spray gun (commonly used caliber is 1.5 - 2.5mm), spraying pressure (generally controlled at 0.3 - 0.5MPa), spraying distance (recommended to be kept at 20 - 30cm) and other parameters, the size and density of the orange grain can be accurately controlled. For example, if you want to get a larger orange grain effect, you can increase the caliber of the spray gun and reduce the spraying pressure appropriately; if you want fine orange grain, do the opposite. At the same time, the temperature and humidity of the construction environment have a significant impact on the orange grain effect. The optimal construction temperature is 5℃ - 35℃, and the relative humidity is not more than 85%. Too high or too low temperature and humidity may cause uneven orange grain or poor drying of the coating.
Drying and curing: After spraying, the coating needs to be dried and cured in a suitable environment. Generally, the surface drying time is 1-2 hours, and the actual drying time is 24-48 hours. During the drying process, avoid dust and debris from contaminating the coating to ensure the final effect.
