Paint for Shutters

Paint for shutters Features: In addition to UV protection, UV shutters offer multiple functional advantages. The UV roll-coating process applies UV coating evenly onto the shutter surface using a UV roll-coating machine, followed by rapid UV curing. This process provides high production efficiency, low paint waste, and a smooth, uniform, and full-bodied finish on the shutter surface without excess paint buildup. The coating rollers are also removable and precisely positioned.

Core Information

 

1. Product Introduction

  • Paint for shutters Features: In addition to UV protection, UV shutters offer multiple functional advantages. The UV roll-coating process applies UV coating evenly onto the shutter surface using a UV roll-coating machine, followed by rapid UV curing. This process provides high production efficiency, low paint waste, and a smooth, uniform, and full-bodied finish on the shutter surface without excess paint buildup. The coating rollers are also removable and precisely positioned.
  • Product Advantages: The UV roll-coating materials are usually UV-based coatings with low VOC emissions, low odor, and solvent-free formulations (e.g., no benzene), meeting environmental protection requirements. The finish exhibits fine roll marks and a smooth surface.
  • Application Range: Suitable for wood-based substrates.

 

2. Core Value Proposition

  • Problem Solved: Ordinary coatings have poor weather resistance, fade or deform under sunlight, emit strong odors, and accumulate dirt in louver gaps, making cleaning difficult.
  • Core Features: UV protection + 15-level scratch resistance; withstands 1 year of outdoor exposure without fading; easy-to-clean louver gaps; extends louver lifespan by 3×.
  • Additional Benefits: Low VOC, benzene-free; 5–7° matte finish; 0-level adhesion; multi-layer roller coating process suitable for mass production.

 

Core Advantages of paint for shutters

 

1. Venetian blind exclusive technology
  • Dual-Protection Formula: UV absorbers + anti-aging resin resist ultraviolet exposure; fading rate ≤3% per year, 70% lower than ordinary coatings; 15-level scratch resistance (special test standard), no scratches during louver opening/closing.
  • Low-Odor Formula: Benzene-free solvent system, VOC ≤5 g/L; safe for immediate use after installation, unlike traditional high-odor coatings.
  • Multi-Layer Roller Coating: 4 layers of primer + 1 layer of topcoat; uniform coating without sagging, no paint accumulation in louver gaps, solving the "dead zone" problem in louver coating.

2. Scene adaptability
  • Exclusive Applications: Residential wooden louvers, commercial office louvers, outdoor sunshade louvers-designed for "high-frequency opening/closing + sun/rain exposure" scenarios.
  • Compatible Substrates: Wooden materials (pine, fir, MDF), focusing on the main louver materials.
  • Application Advantages: Removable coating rollers for precise positioning; uniform coating; UV curing energy 250–300 mJ/cm².

3. Practicality and Environmental Advantages
  • Weather Resistance & Extended Lifespan: Outdoor use for 3 years without deformation or fading; replacement frequency reduced by 75%, maintenance costs lowered by 60%.
  • Easy Cleaning: 5–7° matte finish; dust and dirt can be wiped clean with a damp cloth, with no residue in louver gaps.
  • Compliance Assurance: Low VOC, compliant with EU REACH standards; suitable for export to commercial projects in Europe and the Americas.

Differentiation Objectives

1

Substrate Pretreatment

- Sand wooden louvers (240 grit), remove burrs and dust, control moisture ≤12%

Adapt to wooden louver characteristics, prevent coating cracking

2

Roll Coating Low-Odor Primer (JF-JJ5041)

- Removable roller positioning, uniform coating

Precise coverage with no dead angles, low-odor primer

3

Primer Curing

- UV energy 250–300 mJ/cm², matched power

Fast curing, enhance adhesion

4

Multi-Layer Primer Application

- Repeat 3 layers of primer + curing, fill wood pores

4 layers of primer ensure scratch resistance and weather durability

5

Roll Coating 15-Level Scratch-Resistant Topcoat (JF-JJ8124)

- Control coating amount to avoid accumulation in louver gaps

Strengthen scratch resistance, suitable for high-frequency opening/closing

6

Final Curing + Cooling

- UV energy 280–300 mJ/cm², natural cooling before inspection

Lock in performance, prevent coating brittleness

 

Construction Precautions

 

  • Roll Coating Positioning: Use a removable precision positioning roller; control coating amount on louver edges at 8–10 g/㎡ to prevent paint accumulation.

 

  • Environmental Requirements: Temperature 15–30 °C, humidity ≤65%; avoid high humidity to prevent coating hazing.

 

  • Storage & Handling: Store in a cool, dry place at 5–35 °C; shelf life 12 months unopened, use within 30 days after opening.
