IJmopox HB Coating is a high-quality, low-solvent epoxy coating from De IJssel Coatings. This coating has been specially developed to provide effective protection for polyester substrates against osmosis and also offers excellent corrosion protection on a variety of metals. Thanks to its strong chemical resistance, IJmopox HB Coating is highly resistant to, among other things, salt water and various chemicals.
HB Coating is widely used as a protective primer and provides an ideal base for further finishing with DD Paint High Gloss or DD Paint Semi Gloss.
A major application advantage is that multiple coats of HB Coating can be applied on top of one another without intermediate sanding. If the substrate is coated with a single-pack paint system, this must first be completely removed. The surface should then be roughened with P120–P180 grit sandpaper to ensure optimum adhesion.
NEW: IJmopox HB Coating is available in pack sizes from 0.75 litres and can be supplied in all colours from RAL, Sikkens, NCS and AWLGrip colour ranges.
Benefits of IJmopox HB Coating
- Provides excellent protection against corrosion (steel) and osmosis (polyester).
- Resistant to various chemicals and (salt) water.
- Can be overcoated immediately with most types of antifouling.
- Low in solvents.
- Easy to apply.
Applications
IJmopox HB Coating is suitable for a variety of applications, including:
- Primer for finishing with Double Coat DD Paint.
- Prevention and repair of osmosis in polyester boats.
- Underwater coating for vessels that remain in the water for up to 24 consecutive hours.
Tip: for steel and aluminum substrates, it is recommended to pre-treat the surface with IJmopox ZF Primer first. When applying to wood, we recommend impregnating the substrate beforehand with Variopox injection resin.
Directions for use
Follow the instructions below to apply the epoxy coating correctly:
- Clean, sand and degrease the surface.
- Wipe the surface with a tack cloth to remove any remaining dust.
- Stir the base component thoroughly and weigh out the required amount into a clean mixing container.
- Add the hardener in the specified mixing ratio.
- Mix both components carefully until a homogeneous mixture is obtained.
- Thin the coating, depending on the application method and conditions, with approximately 5% IJmopox Thinner.
- Working at temperatures below 15°C? Allow the mixture to pre-react for 10 minutes.
- Apply the HB Coating evenly using a brush or velour roller.
- Immediately roll over the surface with light pressure to achieve a smooth, even finish.

- LAK000091
-
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.
- Does not apply

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.
- Primer
-
The recommended application temperature range indicates the conditions under which the product can generally be applied and cured properly. Three temperatures matter:
- Air: the temperature in the workshop or outdoors.
- Substrate: the temperature of the surface being treated.
- Product: the temperature of the resin, adhesive or coating itself.
A cold substrate can cause condensation and affect adhesion. At higher temperatures, two-component products may react faster, reducing their working time. Check the dew point and follow the product instructions.
- 5-25 °C
-
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.
- 3:1 (by volume), 83:17 (by weight)
-
The overcoating interval tells you when the next layer of paint, varnish or coating may be applied. Many multi-coat systems specify both a minimum and a maximum interval:
- Minimum overcoating time: the previous layer is dry or cured enough to accept another coat.
- Maximum overcoating time: the period during which the next coat can bond without extra surface preparation under the stated conditions.
Overcoating too early can affect drying or the finish. Once the maximum interval has passed, cleaning and sanding may be needed to ensure adhesion between coats. Temperature and film thickness affect the waiting times.
- 8 hours
-
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.
- 2 hours
-
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 7 m²/L
-
A specific thinner that can be used, where permitted, to adjust a product's application properties or viscosity. The correct thinner and maximum quantity depend on the product. Incorrect thinning can affect coverage, drying and curing.
- IJmopox thinner (5-10%)
-
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, Roller, Spray
-
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 5 houres (at 20 °C)
