Aluwedo® PVDF Kynar 500 Aluminum composite panels are produced with automatic machine using advanced technique introduced from German. There are two layers of high-strength aluminum sheets made from A1100, A3003 and A5052. The panel is formed by low density polythene (LDPE) and DUPONT adhesive film under high temperature and high pressure. The outermost aluminum sheet has been coated with 70% fluoro polymer resin-based coating. And the innermost aluminum sheet is protected with an anti-corrosion primer coat.

Manufacturing Techniques
1. Cold mounting techniques only
2. Saw cutting
3. Routing
4. Die cutting (punch press die set is required; not a steel rule die)
5. Forming curves
6. Grooving

The production line of Aluwedo signage high gloss finish aluminum composite panel is a complex work integrating various machining, assembling and inspection procedures. For more details please download ALUWEDO processing guidelines.

Excellent torsion strength
With varieties of advanced equipment and strict control, ALUWEDO panel features high strength, excellent torsion strength, large bending strength, and excellent weather resistance

Easy processing and installation
ALUWEDO panel is easy to be processed for its light weight (3.5-5.5kg/sqm). All of the cutting, milling, planning, slotting, side-folding and curving operations can be easily fulfilled with simple tools used for processing timber and metal. Indoor and outdoor decoration can be implemented simultaneously so as to raise working efficiency and cutting working time

Excellent impact resistance
ALUWEDO features good impact resistance, toughness, and bending rigidity. It will not be damaged when suffering from sand blown by wind

Excellent weather resistance
ALUWEDO panel coated with fluoro-carbon (PVDF) resin features good tightness, strong adhesion, alkali resistance, and powdering resistance. It can be used for 20 years without getting fade

Various color available
Dealing with the surface of aluminum material, and with the application of Henkle technology, it makes the paint and ALUWEDO stamped with a very strong even force. Various color are prepared for option

Easy maintenance
ALUWEDO panel needs to be maintained and cleaned after several years' use. Only neutral cleanser and water is needed. It will as bright as new after cleaning

Panel Specifications
Architects and building owners should determine which panel specification is needed, along with the painting color. In order to ensure the paint performance expected for a given application, AAMA 2605 is the high-performance exterior specification. A paint meeting this specification would be a 70% fluoro polymer resin-based coating. These finishes exhibit outstanding resistance to humidity, color change, chalk, gloss loss and chemicals. An application for this finish would include monumental architectural projects. We choose Kynar 500 for the PVDF coating which allows for 15 years exterior guarantee.
