Versatech-EXT

 

UV and Anti-Graffiti rated films for challenging environmentsThe Ultimate Exterior film. Time may pass but the quality remains.

 

 

Versaetch-EXT is a multi-layer film. The top layer is a polyvinylidene fluoride film (PVDF), the second one of transparent polymethylmethacrylate (PMMA) and the base film of pigmented PMMA. Infrared-reflecting pigments in the base film reduce heat build-up of substrate below. 

 

 

 

 

 

 

 

 

 

 

 

The following video highlights the durability and strength of the Versatech anti grafitti film enabling easy maintenance on exterior applications.

 

 

ACCELERATED WEATHER TESTING

After a massive 25 000 hours in an XENOTEST – Slight loss of gloss but no chalking or other adverse effects

Comparable pre-painted coil sample after 2000 hours

Result – STUNNING! Far exceeds painted material

Versatch Walnut V Sample

Greyscale - Left: 5, Right: 3-4

Versatech Silver Sample

Left: Original, Right: 25.000 h

Greyscale - Left: 5, Right: 4

Significant loss of gloss and chalking visible - Left: Original, Right: 2000 h

Salt Spray Testing

Independant Salt Spray testing for 2000 hours provided a stunning result that far exceeded pre-painted metals - Over 50% gloss retention

 

Conclusion

Versatech-EXT film far outperforms commonly used pre-painted materials in both UV and Salt Spray tests.

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

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.

Fire Properties Tested to AS1530. 3 Ignitability Index: 0 Spread of flame: 0 Heat evolved index: 0 Smoke developed index: 5 Electrical Resistance 200-300 volts per 25um of film thickness

Abrasion Resistance

Excellent

 

Tested to ISO 105-X12 - Grade 5
