Data sheet • July 2011
The economic solution for interior and exterior applications.
colofer ® classic 25 is the time-tested and economic standard solution for exterior and interior applica-
tions without special demands and under regular atmospheric stress. colofer ® classic 25 is characte-
rized by close to unlimited color selection and a UV resistance class of RUV 3 pursuant to EN 10169-2.
With more than 20 years of experience, continuous development and further optimization, colofer ®
classic 25 has become the first choice for standard applications. colofer ® classic 25 is available with
a protective film upon request.

Structure colofer ® classic 25
2-layer system, approx. 25 μm
Typical applications:
p Polyester cover coat, approx. 20 µm
p Primer coat, approx. 5 µm
p Substrate:
Hot-dip coated steel strip with a zinc layer thickness ranging between
200 and 275 g/m² or a zinc-magnesium coating with a minimum of 120 g/m²
p Bottom-side coating:

1) ® A slightly higher incidence of crack formation is to be expected in colofer corrender coated.
2) No delamination of coating on even surfaces throughout duration of guarantee. Some colors, especially those of darker shade, may
be subject to limitation. Color shades will change as a result of long-term stress at high temperature. Requests for further technical
information from your contact partner are recommended.
3) UV resistance depends heavily on color and the respective RUV class cannot be guaranteed for all colors. Colors covered by UV
resistance classes are noted in table 7 of the Technical Terms of Delivery for colofer ® . Please contact your responsible technical
expert for assistance in unclear cases.
4) ® The indicated guarantee periods apply only under compliance with colofer guarantee provisions.
5) The guarantee becomes applicable when delamination of the coating occurs on more than 5% of the installed surface area.
6) The guarantee becomes applicable when the limit values set forth in the Natural Weathering Standard are exceeded.
More detailed information on the natural weathering resistance of selected colors is available upon request. Because the exact color
selected plays an important role, it is necessary that the respective paint manufacturer contact our technical expert for consultation.
