Kalzip colours – limitless variety

Modern building technology makes the highest demands on the resistance of the materials employed to weathering and corrosion. Coloured Kalzip aluminium profiled sheets are the result of state-of-the art surface refinement technologies.

Consistent colour quality

The aluminium strips, which are coated using the coil-coating process, undergo a large number of elaborate work steps. Depending on the type of coating, they undergo different pre-treatment processes and are finished in the colour requested or sealed with a clear varnish. Aluminium strips with a single-sided coating are provided with a protective coat of varnish on the rear side. Only highquality stove enamels which have a polyester, PVDF or CFTE base are used in order to achieve a weather-resistant and colourfast coating.

The coil coating process is monitored in accordance with the standards of the ECCA (European Coil Coating Association). Important criteria here are: colour tone, degree of shine, thickness of varnish, hardness of varnish, adhesion of varnish and malleability. Long-duration tests such as acid salt spray tests, QUV B tests, condensation tests in an SO2-saturated atmosphere and outdoor exposure tests in aggressive environments are also carried out.

Kalzip profiled sheets with polyester coating

The coating is robust and resistant to scratches; it has very good forming characteristics and good resistance to weathering and UV light. Kalzip profiled sheets in a polyester execution are mainly used in locations with normal environmental influences.

Kalzip profiled sheets with PVDF coating

This coating is particularly good for aggressive environments and extreme climatic conditions, e.g. near to salt water. Profiled sheets in PVDF quality are characterised by outstanding UV-resistance, have very good forming characteristics and are used primarily for facade design.

Kalzip ProTect coating

For the protection of the surfaces, Kalzip additionally offers a high-quality and extraordinarily weatherresistant high-end special coating on the basis of a polymer technology using fluorocarbon (FLP). It is characterised by extremely high resistance to scratching, optimum stability of colour tone and shine and a considerably higher surface hardness and temperature resistance.

Characteristics of the ProTect coating:

• Available for RAL, NCS and metallic colours
• Outstanding long-term characteristics with very low chalking tendency
• Very good resistance to dirt due to a Teflon-like behaviour, resulting in a lower cleaning requirement
• Resistant to chemicals, even to aggressive emissions such as aircraft exhaust gases
• Due to the FLP technology and an additional coat of clear varnish, an “AntiGraffiti effect” is achieved that offers effective protection against vandalism
• Also available in high gloss finishes
• Conforms to the examination conditions of the Florida test
