White Glue’s Functions and Usage
FAQ 2025-09-22 82
White glue is a water-soluble adhesive made from vinyl acetate monomer via polymerization with an initiator. It’s commonly referred to as white glue or PVAC emulsion, and its chemical name is polyvinyl acetate adhesive. It’s synthesized from acetic acid and ethylene to form vinyl acetate, with titanium dioxide (low-grade products often use light calcium, talc, or other powders). This emulsion polymerizes to form a thick, milky white l
Applications of Optical PET Film in the Electronics Industry
FAQ 2025-09-22 59
Optical-grade PET protective film boasts excellent optical properties, including low haze, high transmittance, smooth surface, and tight dimensional tolerances. It is primarily used in high-end LCD devices as external diffusers, reflective films, brightening films, antistatic films, touchscreen protective films, and films for flexible displays. Among the upstream and downstream raw materials for LCDs, optical films are used in backlight units, po
How does powder coating work?
FAQ 2025-09-22 71
Surface Preparation Before powder coating, manufacturers thoroughly prepare the substrate. This stage is crucial because a clean, properly pre-treated surface ensures excellent adhesion and minimizes defects. Key steps include: Cleaning and Degreasing: Removes oil, grease, and contaminants using chemical cleaners or solvents. Mechanical Abrasion: Methods such as sandblasting or abrasive blasting roughen the surface, increasing the contact area. E
Competitive landscape and market innovation
FAQ 2025-09-22 57
As competition intensifies, powder coating manufacturers are investing in R&D and technological innovation to differentiate their products. Some notable trends include: Low-bake and UV powder coatings Traditional powder coatings require curing at 150–200°C, but low-bake technology allows curing at 120°C or lower, making them suitable for heat-sensitive materials such as plastics and composites. UV protein coatings reduce energy consumption by
Fluorocarbon coatings: properties, applications and advantages
FAQ 2025-09-22 65
1. What is a fluorocarbon coating? Fluorocarbon coatings use fluororesins as their primary film-forming substance. Fluorocarbon coatings, also known as fluorocarbon paints or fluororesin coatings, are characterized by strong carbon-fluorine bonds and the high electronegativity of the fluorine element, resulting in excellent performance. Key properties include: Excellent weather resistance High and low temperature resistance Excellent chemical re
The Difference Between Fluorocarbon Spraying and Powder Coating
FAQ 2025-09-19 85
Electrostatic spraying is divided into powder spraying and fluorocarbon spraying. Powder spraying uses materials such as polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resin, and epoxy/polyester resin, and can be formulated into a wide variety of colors. Powder spraying features include manual and automatic hanging spraying equipment, simple application, coating thickness of 30 microns or greater, and excellent impact, abrasion,
Advantages and Disadvantages of Powder Coatings
FAQ 2025-09-02 98
Advantages Powder coating offers several important advantages: Durability and Performance: The robust film is highly resistant to scratching, chipping, and fading. In abrasion tests, powder coating can outperform liquid paint by 30-50%. Environmental Benefits: The process emits virtually no VOCs, and powder overcoating is recyclable. These factors contribute to reduced environmental impact and regulatory compliance. Aesthetic Versatility: Powder
Powder coating colors and finishes
FAQ 2025-09-02 118
Powder coatings are available in a variety of colors, categorized by gloss level, texture, and specialty effects. Gloss Levels High Gloss (80–100% reflectivity) – Provides a stylish, mirror-like finish, commonly used in automotive applications. Semi-Gloss (40–79% reflectivity) – Balances sparkle and subtlety, ideal for architectural coatings. Matte (10–39% reflectivity) – Reduces glare and creates a sophisticated, soft appearan
Powder coating color measurement and variation control
FAQ 2025-09-01 101
Powder coatings were originally developed for metal corrosion protection, but with advances in production technology and growing environmental awareness, color consistency has become equally important for decorative applications. Industries such as appliance manufacturing, metal doors, aluminum profiles, and machinery require highly consistent coating color between batches to maintain product quality and brand reputation. 1. Measuring Powder Coa
The rise of powder coatings in the automotive industry
FAQ 2025-09-01 96
Introduction In today’s automotive industry, environmental responsibility is closely tied to performance. One technology leading this transformation is powder coating automotive parts. As manufacturers seek sustainable alternatives to solvent-based coatings, powder coatings have become a high-performance, low-emission solution, particularly popular for wheels, chassis, engine components, and trim. What is automotive powder coating? Automot
Causes of gloss loss in powder coatings
FAQ 2025-09-01 85
(A.) Discoloration (gloss loss) is often caused by excessively long curing times or high curing temperatures during powder coating curing. Because the pigments in red, yellow, and blue powders are not heat-resistant, prolonged high-temperature curing beyond their curing range can easily cause the powder to yellow. Excessive high-temperature curing can also cause resin degradation and brittleness. (B.) Varying gloss levels between batches of powd
