The Calendering process uses heat to melt a plasticized vinyl resin, which is then squeezed between rollers to produce a vinyl film.
- Monomeric Calendered Vinyl, generally 80-90 microns thick, is mostly used for interior applications, such as POS, way finding etc. as it is prone to light fastness and shrinkage when used outdoors. With an outdoor life of 2-3 years it is only suitable for short term exterior use.
- Polymeric Calendered Vinyl, generally 70-80 microns thick, offers an extended outdoor life of
5-7 years, but even with a reduced film thickness, is not suitable for uneven surfaces such as corrugations and rivets. Therefor it is not recommended for use on vehicles.
This process uses solvents to liquify the vinyl resin, which is then floated onto a highly polished surface. The resultant film is extremely stable and can be used for very demanding outdoor applications. Generally around 50 microns thick, this vinyl offers excellent conformity over rivets, corrugations and textured surfaces. With an outdoor life of 8-10 years, it will withstand extreme variations in temperature and humidity.
Ideal for window graphics and long term exterior use, such as vehicle liveries, military and marine applications, and industrial signage.
- Emulsion based Acrylics can be affected by water and are therefor
not suited for outdoor use.
- Solvent based Acrylics are more widely used, being water resistant
and providing better adhesion to a larger variety of surfaces.
Unless stated otherwise we always use Cast or Polymeric Calendered Vinyl,
with Solvent based Adhesive, to ensure the longevity of your sign.
The expected outdoor life of vinyl is governed by the type (calendered or
cast), the adhesive used, and the colour fastness. Some colour pigments are
more prone to fading due to their chemical formulation.
NB: We use the RAL system for colour matching.
- Minimum Application Temperature - this varies between types of
vinyl, but a safe average figure to work to is 10°C
- Intermittent Service Temperature - the min/max temperature an
applied vinyl can withstand for short periods.
- Constant Service Temperature - the min/max temperature an applied
vinyl can withstand on a constant basis throughout its life duration.
