Akzo Nobel



The CERAM-A-STAR®1050 coating system is the most innovative silicone protected polyester technology available in the market today. It is designed to contribute color and help protect metal coils that are later fabricated into construction panel products for metal siding and roofing. Years of continuous research and actual outdoor testing have guided our ability to produce CERAM-A-STAR®1050 in a wide array of colors that blend well with collateral construction materials.


  • Outstanding performance in a variety of normal climatic conditions.
  • Ceramic/Inorganic pigmentation for excellent color retention and durability.
  • Good hot hardness and scratch resistance
  • Extensive color selection and improved fade resistance
  • Improved chalk resistance
  • Improved gloss retention
  • Smooth, fast application
  • Batch-to-batch consistency
  • Excellent roll-forming
  • Long-life durability


CERAM-A-STAR®1050 coatings are intended to be factory applied, to metal substrates according to Akzo Nobel Product Data Sheets, over primer, by the coil coating method only. This process efficiently and economically applies primer and CERAM-A-STAR®1050 colors according to exact film thickness specifications across the entire panel width. In this process, coatings are applied to specified metal substrates that have been thoroughly cleaned and chemically pretreated in accordance with manufacturer's instructions to optimize adhesion, forming and weathering characteristics. CERAM-A-STAR®1050 coatings and primer must be baked and cured in factory ovens at temperatures ranging from 400°-480°F. Color, gloss, hardness, cure, flexibility and adhesion are only a few of the performance characteristics monitored in the quality control process. The coil coating process is highly efficient with nearly 100% transfer efficiency to the metal coils. This process collects and destroys almost all volatile organic content (VOC's) usually associated to any painting process.


Test methods established by ASTM (American Society for Testing and Materials).


Physical Properties of the Coating:

Film Thickness (ASTM D1005) - 0.20 mils (5 microns), minimum, primer; 0.90 mils (23 microns), minimum, total film thickness
Specular Gloss (ASTM D523) - 35% ± 5%, Lower or higher gloss upon request.
Hardness (ASTM D3363) - F minimum
Cross-Hatch Adhesion (ASTM D3359) - No removal Bend Adhesion (ASTM D4145) - No loss of adhesion Humidity
Resistance (ASTM D2247) - 1000 hours: Pass - actual performance varies with pretreatment and substrate.
Salt Spray Resistance (ASTM B117) - 1000 hours: Pass - actual performance varies with pretreatment and substrate.
Weatherometer Test (ASTM D822) - 2000 hours; no checking, blistering or adhesion loss.
Color Change (ASTM D2244) - Exterior color change not exceed 5 NBS units after a 2000 hour weatherometer test
Chalking Resistance (ASTM D4214, Method A) - No chalking greater than #8 after a 2000 hour weatherometer test
Exterior Weathering (ASTM D4141) - 5 ?E max color change (ASTM D2244) and at least #8 chalk rating (ASTM D4213) after 10 years of Florida exposure (45º South)
Abrasion Resistance (ASTM D968) - 30 liters/mil minimum


CERAM-A-STAR®1050 colors are made from the highest quality ceramic/inorganic pigments in a wide range of colors. ISO 9001 certified Akzo Nobel manufacturing methods at our Columbus Headquarters facility uniformly distribute pigments into a proprietary silicone protected polyester resin that has proven, under years of harsh 45° South Florida exposure, to resist changes in color and general appearance, while preserving film integrity and coating properties.
