Reverse Roll Coating

Huzhou Jiafu Macromolecular Material Co., Ltd. is one of the most reliable manufacturers and suppliers of reverse roll coating in China. Welcome to wholesale bulk high-grade reverse roll coating for sale here from our factory. We also accept customized orders.

1. Product Introduction

• Reverse roll coating : UV coatings are liquid paints that cure rapidly under ultraviolet (UV) light, forming a durable protective layer.
• Key Advantage – Fast Curing: Under UV lamps, the coating can dry within seconds, significantly speeding up the production process.
• Environmentally Friendly: UV coatings contain no volatile substances, making them safe for both the environment and application personnel.
• Wide Range of Applications:They can be used on furniture, photo frames, moldings, phone cases, automotive parts, and more.

2. Core Value Proposition

• Solving Thick-Coating Issues: Ordinary single-direction roller coating has low coverage (≤30 g/m²) and thin layers, unable to fill minor scratches; thick coatings tend to sag and show roller marks.
• Core Features: Forward-and-reverse dual-direction roller coating technology, single-pass coating up to 60 g/m², fills minor scratches without roller marks, achieves 30% semi-gloss finish, and improves production efficiency by 40%.
• Additional Assurance: Low VOC, high solids content, 0-grade adhesion, HB hardness scratch-resistant, curing energy 150–200 mJ/cm², suitable for mass production of thick coatings.

1. Core technologies of forward and reverse roll coating

• Dual-Direction Roller Coating Principle: Forward rolling evenly spreads the paint, while reverse rolling precisely controls thickness and eliminates roller marks. The V-shaped gap design ensures full adhesion of the coating and fills minor substrate scratches (≤0.1 mm), solving the "thin coating + roller marks" issue of single-direction roller coating.
• High-Viscosity Adapted Formulation: Viscosity 5000–6000 CPS (GB/T 9751.1-2008), optimized for roller speed, achieving 60 g/m² high coating thickness. Thick coatings resist sagging, with 50% higher stability than ordinary roller coatings.
• Rapid Curing System: Curing energy 150–200 mJ/cm², second-level curing, preventing sagging or contamination after thick coating and ensuring efficient mass production.

2. Thick coating scene adaptability

• Exclusive Scenarios: Decorative panels, solid wood flooring, calcium silicate boards, cabinet doors, and other applications requiring "thick protective coating + defect filling."
• Compatible Substrates: Wood panels, calcium silicate boards, metal panels, focusing on core substrates for thick coatings (distinct from thin-coated plastics or small substrates).
• Application Advantages: Single-pass thick coating without multiple applications; production line daily capacity reaches 8,000 ㎡, saving 2 process steps compared with ordinary roller coating.

3. Practicality and Cost Advantage

• Enhanced Protection: Thick coating achieves wear and scratch resistance ≥1,500 cycles; substrate service life doubled, renovation costs reduced by 60%.
• Defect Filling: No extra sanding required to repair minor scratches; substrate pretreatment costs reduced by 30%.
• Environmental Compliance: High solid content, low VOC, solvent-free; meets workshop environmental standards and supports export.

• Roller Gap Adjustment: Adjust the roller gap according to substrate thickness (0.1–0.3 mm) to ensure accurate coating weight of 60 g/㎡.

 

• Viscosity Control: Strictly maintain 5000–6000 CPS; too low causes sagging, too high affects uniformity.

 

• Storage Conditions: Store sealed in a cool, dry place at 5–35℃; shelf life 12 months unopened, use within 30 days after opening.
