| UV Coating and Weatherability |
PVDF layer (transparent)
Accelerated testing after 25 000 hours. Result – Excellent with minimal fading, no chalking.
Far outperforms painted materials
(see pictures and further data below)
Standard Test Method: EN 513 – method 1 |
Anti-Graffiti |
The non-sacrificial PVDF top layer provides a very low surface tension that will continue to repel graffiti time after time and allow effortless removal.
REMOVAL AGENT For this purpose use cleaning agent: Graffinet Plexiclean from EAG - www.eag.eu (or Versatech) |
| Heat Reflective |
PMMA base layer has heat reflective properties to help reduce the substrate temperature |
Salt Spray |
Independent accelerated testing after 2000 hours
Result – Excellent with no deterioration or adverse effects
Far out performs painted materials (see pictures and further data below) |
| Adhesion to substrate |
To AS2728 - A to D rating min |
Adhesive |
Proprietary which combines flexibility with high temperature and humidity resistance |
| ABRASION, CHEMICAL, ELECTRICAL AND FIRE |
|
Due to the excellent chemical resistance of the PVDF coating the EXT films are resistant to most organic acids and bases, aliphatic and aromatic hydrocarbons, alcohols and halogenated solvents and building materials e.g. cement, gypsum. With the exception of fluorine, our film is also resistant to halogens (chlorine, bromine, iodine).
Not resistant to high polar organic solvents (e.g. acetone, ethyl acetate, dimethlyforamamide, dimethylactamide), fuming, sulphuric acid, amines and basic liquids with pH>12. Please take into account that the chemical compatibility is strongly dependent on time, temperature, concentration, chemical condition and state of aggregation of the substance. Please be careful near any cut edges of the film e.g. welded corners, as the film is unprotected in the cross section. Side penetration of chemicals cannot be excluded. |

| FORMABILITY AND WORKING THE MATERIAL |
| Formability |
Can be folded, roll formed, guillotined, drilled, deep drawn, punched and lock seamed.
Form at a min substrate temperature of 24 deg to avoid any possible stress whitening on tight bends |
Joining |
Can be joined by using a variety of techniques including:
- Mechanical fixing
- Adhesive bonding
- Snitching
- Clinching
- Specialised welding techniques |
