Core Information
1. Product Introduction
- Vacuum plasma spraying: 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
- Problem Solved: Ordinary spray coating for small or irregular-shaped parts often leaves dead corners, uneven coating, requires separate coatings for matte/high gloss, and emits strong odor.
- Core Features: Vacuum environment spray coating ensures no dead corners; small or irregular parts achieve uniform coating; matte or high gloss selectable in a single coat; low VOC and environmentally friendly.
- Additional Assurance: HB hardness for scratch resistance, Level 0 adhesion, curing energy 200-250 mJ/cm², suitable for mass production.
Core Advantages of vacuum plasma spraying
1. Vacuum spraying technology
- Vacuum No-Dead-Zone Coating: In a vacuum environment, the coating uniformly wraps small or irregular-shaped parts; edges and gaps have no dead zones; coating thickness deviation ≤ 2 μm.
- Dual Gloss Compatibility: The same formulation can achieve matte (5–7°) or high gloss (≥80°) by adjusting curing parameters, no need to change paint.
- Low Viscosity Adaptation: Viscosity 40–45 cps (2# cup), easily atomized; coating on small parts is thin, uniform, and free of sagging.

2. Small item scenario adaptability
- Dedicated Scenarios: Furniture fittings, decorative moldings, irregular-shaped wooden pieces, small plastic parts - "small & irregular" applications.
- Compatible Substrates: Small wooden parts, ABS plastic, PC plastic, focusing on core small-part materials.
- Application Advantages: Compatible with vacuum spraying equipment; integrated spraying and curing process greatly improves efficiency.

3. Flexibility and cost advantage
- Flexible Adaptation: Dual gloss options meet different order requirements, reducing inventory costs by 50%.
- No Dead-Zone Guarantee: Uniform coating on small/irregular parts, reducing defect rate from 10% to 1.5%.
- Environmental Compliance: Low-VOC, solvent-free, compliant with export environmental standards for small parts.

Differentiation Objectives |
|
1 |
Substrate preparation |
Sand small/complex parts (400 grit), clean oil and dust, blow off with compressed air |
Suitable for fine-detail small parts |
|
2 |
Vacuum loading |
Place parts into vacuum coating equipment, seal and vacuum (≥ -0.08 MPa) |
Prepares vacuum environment |
|
3 |
Vacuum spraying |
Atomized coating evenly covers parts, no dead corners, film thickness 15–25 μm |
Ensures full coverage without dead zones |
|
4 |
Leveling |
Allow natural leveling inside equipment for 30 s to prevent pinholes |
Optimizes coating surface smoothness |
|
5 |
UV curing |
Energy 200–250 mJ/cm², time 2–3 s |
Fast curing, prevents part deformation |
|
6 |
Post-process inspection |
Check for no dead corners, no runs, gloss meets standard |
Ensures quality of small/complex parts |
Construction Precautions
- Vacuum control: ≥ -0.08 MPa; otherwise, dead corners or bubbles may occur.
- Film thickness control: 15–25 μm; too thick causes runs, too thin provides insufficient protection.
- Storage: Store sealed at 5–35 °C; shelf life 12 months unopened, use within 30 days after opening.
