1. What is the purpose of embossing on aluminum coil?
Stucco embossed finish also called “orange peel” pattern. it with some functions as ideal insulation materials:
1.Boost the hardness of the surface
2.Enhance the density and resistance of the surface
3.Expand the area that can bear force to improve surface friction
4.Minimize strong reflections of light
5.Stucco pattern can reduce sunshine reflect and hide small scratches.
2. Why Polysurlyn?
Polysurlyn (ionomer resin) offers better puncture resistance, adhesion to aluminum, and flexibility at low temperatures than traditional polyethylene or PVC films. It also resists oils, greases, and mild chemicals, making it ideal for industrial environments.
3. Application of embossed aluminum coil with polysurlyn moisture barrier:
| Application | Use Case | Why It Works |
|---|
| Pipe Insulation Jacketing | Oil/gas pipelines, refineries, chemical plants, district heating/cooling | Polysurlyn (Surlyn®-like ionomer) provides a seamless moisture barrier; embossing improves handling, wind resistance, and aesthetics; aluminum adds mechanical strength and UV resistance. |
| Tank & Vessel Cladding | Storage tanks, process vessels, LNG facilities | Prevents water vapor ingress into insulation (e.g., mineral wool, foam), avoiding corrosion under insulation (CUI) and maintaining thermal performance. |
| Building Envelope | Roofing, wall cladding, curtain walls (especially in high-humidity or coastal areas) | Acts as a weather-resistant barrier (WRB) with embossed texture for drainage and reduced wind uplift; compatible with insulation and air barriers. |
| Marine & Offshore | Ship hulls, offshore platforms, subsea equipment | Resists salt spray, seawater, and harsh marine environments; embossing enhances grip and durability during installation. |
| Industrial Equipment | Boilers, heat exchangers, HVAC ductwork | Protects insulation from moisture, dust, and chemicals; embossed surface is easier to clean and inspect. |

5. Core Benefits:
a: Moisture Barrier: Polysurlyn’s low water vapor transmission rate (WVTR) blocks liquid water and vapor, preventing insulation degradation and CUI.
b: Corrosion Resistance: Aluminum’s natural oxide layer, combined with the ionomer film, resists UV, chemicals, and salt, extending service life.
c: Mechanical Strength: Embossing increases rigidity, impact resistance, and scratch resistance compared to flat aluminum; easier to form around bends and joints.
d: Ease of Installation: Lightweight, flexible, and available in wide rolls (800–1300 mm typical) for faster coverage; embossed texture improves handling and reduces slippage.
e: Cost Efficiency: Eliminates the need for separate moisture barriers (e.g., felt, foil) and reduces maintenance due to longer service life.
6.Typical Specifications:
Aluminum Thickness: 0.3–2.0 mm (common: 0.4–0.7 mm).
Alloys: 1060 (pure aluminum, ductile), 3003 (aluminum-manganese, higher strength and corrosion resistance).
Polysurlyn Film: Heat-laminated to one or both sides; thickness ~20–50 μm; bonds well to aluminum and insulation adhesives.
Embossing Patterns: Orange peel, diamond, or custom textures for grip, drainage, or aesthetics.
