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.
- Finish coat

Gloss level indicates how much light a dry paint or coating reflects and how the finished surface looks.
- Matt: little reflection and a subdued appearance.
- Satin: a gentle sheen between matt and high gloss.
- High gloss: stronger reflections and a more pronounced colour, although surface imperfections may become more visible.
Gloss can be measured in gloss units (GU) at a specified angle. Terms such as matt and satin do not necessarily mean exactly the same thing across manufacturers. Substrate condition and application also affect the final appearance.
- High gloss

The recommended layer thickness is the thickness at which you apply each coat of paint, coating or resin. It is usually given in micrometres (µm) or millimetres (mm).
- Wet film thickness: the thickness immediately after application.
- Dry film thickness: the thickness after drying or curing.
For a coating with 60% solids by volume, a wet film of 100 µm will theoretically produce a dry film of approximately 60 µm. Film thickness affects coverage, protection and drying. Always check whether the manufacturer specifies wet or dry film thickness.
- 35-50 µm (dry)
-
Density describes the mass of a material per unit volume. Values may be given in g/cm³, kg/L or kg/m³; 1 g/cm³ equals 1 kg/L. For example, one litre of a liquid with a density of 1.2 kg/L weighs approximately 1.2 kg. Density helps convert between weight and volume, but it can vary with temperature.
- Approximately 1.3 kg/L
-
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.
- 12 months
-
Mixing ratio indicates how much of each component is needed, for example resin (A) and hardener (B). A ratio of 100:50 by weight means 100 grams of A to 50 grams of B; by volume you might use millilitres. Weight and volume ratios are not necessarily the same because the components may have different densities. Accurate measuring is important for proper curing.
- 67:33 (by weight)
-
A paint or varnish layer is dust-dry when settling dust is less likely to stick to the surface. It may not yet be touch-dry, ready for overcoating or suitable for loading; these are different stages of drying and curing.
- Approximately 30 minutes
-
Curing time is the period a product needs to reach a specified stage of cure. It is usually given in hours or days, often at a reference temperature such as 20 °C. A product may be tack-free or safe to handle before reaching its full mechanical and chemical resistance. Film thickness and mixed quantity may also affect the time.
- 7 days
-
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: 59%
-
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.
- Approximately 12.9 m²/kg

- 0.75 L (base + hardener)

Working time is the period during which a product remains workable after mixing or activation, usually given in minutes at a specified temperature, often 20 °C. With reactive resins, the chemical reaction also continues in the mixing container, and larger quantities or higher temperatures can shorten this time. Working time is different from gel time and full curing time.
- Approximately 240 minutes (at 20 °C)
