The right film thickness depends on the finish you are applying. Staying within the specified range for your chosen product is important for both appearance and performance:

• Smooth finishes: 60–80 µm
• Fine texture matte: 70–90 µm
• Rough texture glossy: 90–120 µm

Curing conditions for Series 89 coatings vary depending on the exact finish chosen:

 

It is essential to measure substrate temperature, not oven air temperature, and to stay within both the minimum and maximum curing times. Under- or over-curing can affect mechanical properties and visual appearance. Full curing parameter charts are available in the Product Data Sheet!

At a film thickness of 60 µm, Series 89 yields a theoretical coverage of 9.8 to 13.8 m² per kilogram, depending on the specific gravity of the color chosen. Specific gravity ranges from 1.3 to 1.7 g/cm³ and varies with pigmentation: lighter colours and whites typically sit at the lower end of the gravity range and therefore cover more area per kilogram, while heavily pigmented or metallic variants sit higher. For practical planning purposes, coverage at thicker film thicknesses, such as the 90 to 120 µm required for rough texture glossy, will be proportionally lower. The TIGER Coverage Calculator provides detailed guidance on estimating coverage for specific products and film thicknesses and is available for free.

Series 89 powder coatings should be stored in dry conditions at a temperature of no more than 25 °C, away from direct sunlight and extended heat exposure. Storing the product outside these conditions, particularly in warm or humid environments, can affect powder flowability, electrostatic behaviour, and surface quality after application. Series 89 usually comes with a 12-month shelf-live, which should always be observed; powder used beyond expiry falls outside the product specification.

No. Series 89 is an epoxy-polyester hybrid formulated exclusively for interior use. The epoxy component in the formulation is sensitive to UV radiation: prolonged outdoor exposure will cause chalking and colour fade. For exterior applications, TIGER recommends polyester-based series such as Series 29 for architectural use or other UV-stable products from the TIGER Drylac® exterior range.

Low-cure means that full film hardening is achieved at relatively lower substrate temperatures compared to standard powder coatings. Series 89 cures from 160°C substrate temperature (versus the typical 180–200°C range of standard systems). This allows operators to save energy in the curing oven and can be advantageous when coating heat-sensitive assemblies or when running high-throughput lines where shorter cycle times at lower temperatures are beneficial.

Series 89 and Series 09 are both hybrid powder coating systems designed for interior use, with largely similar mechanical and chemical properties, as well as substrate compatibility. The key differences lie in curing and product selection:

Series 89 is a low-cure formulation that works at temperatures starting at 160°C, offering energy savings and better compatibility with heat-sensitive components, while Series 09 cures at standard temperatures (starting from 180°C substrate temperature). When it comes to finishes and effects, the two series complement each other perfectly. Series 09 offers a broader decorative range, including hammertone, antique, and metallic effects (which are not available in Series 89), as well as over 30 RAL colors in a smooth glossy finish. Conversely, Series 89 serves as an ideal complement for fine and rough texture finishes, covering many options that are not available in Series 09, while offering a more limited selection of smooth glossy RAL colors.

Yes. Series 89 can be applied to steel and galvanized steel with appropriate pretreatment.
