The technical product category, such as primer, resin, hardener or cleaner. It explains the product's purpose and helps you find other products with a similar function.
- 1K Primer
-
The materials, substrates or tasks a product is intended for. A general claim such as 'suitable for plastics' does not mean it works with every type of plastic; the specific substrate and its preparation still matter.
- Polyester boten, Stalen-boten
-
The recommended number of coats needed to achieve the intended coverage, thickness or protection. Highly absorbent substrates or different application methods may require additional coats. Allow for the specified time between coats.
- 2-4 coats
-
The period for which an unopened product remains usable under the specified storage conditions. Check whether the period starts from the manufacturing date or another date. Shelf life may be shorter after opening, especially for products sensitive to air or moisture.
- 24 months
-
The time until the surface no longer feels tacky to a light touch. The material underneath may still be soft, so tack-free does not mean fully cured or ready for heavy loading.
- 3 hours (15 °C)
-
Minimum application temperature is the lowest temperature at which a product may be used according to the manufacturer. The limit can apply to the air, substrate and product itself.
At lower temperatures, resins and coatings can become thicker and cure more slowly. Moisture can also condense on a cold substrate and reduce adhesion. Check the dew point and measure the surface temperature before starting. A longer drying time does not automatically make application below the specified minimum acceptable.
- 5 °C
-
The waiting time before an applied layer is dry or hard enough to sand without smearing or damage. Sanding too early can also clog the abrasive quickly. Layer thickness and temperature affect this time.
- 18 hours (15 °C)
-
Solids content is the proportion of material remaining after volatile components have evaporated from a coating. It is stated as a percentage by weight or by volume (%); these are not interchangeable. Volume solids content helps estimate dry film thickness: with 60% volume solids, a 100 µm wet film will theoretically produce approximately 60 µm of dry film.
- Approximately: 48%
-
Consumption or coverage describes how much product is needed for a given surface area. Consumption may be stated in g/m² or kg/m², while coverage is often given in m²/L or m²/kg. A consumption of 0.2 kg/m² means a theoretical 200 grams per square metre. Actual use depends on film thickness, substrate absorbency, application method and waste.
- Practical: 9 m²/L
- Net contents
- 2.5 L, 750 ml
-
The application or processing methods specified by the manufacturer, such as brushing, rolling, spraying, casting or hand laminating. The chosen method can affect consumption, layer thickness and finish.
- Brush, Velour roller, Felt roller
-
VOC content (volatile organic compounds) indicates the amount of these substances in a product, usually expressed in g/L (grams per litre). They may evaporate during application and drying. The value describes the composition, but actual exposure also depends on how much is used, ventilation and the application method.
