| Packaging | 18.9 L (5 US gal.) units |
|---|---|
| ENVIRONMENTAL INFORMATION | Potential LEED® Canada Credits |
| APPROVALS / CERTIFICATES | Meets the requirements of CFIA and USDA for use in food plants. |
| Shelf Life | 1 year in original, unopened packaging under proper storage conditions. |
| Storage Conditions | Store dry at temperatures between 5 °C to 32 °C (41 °F to 89 °F). Protect from freezing. If frozen, discard. |
| Solid content by volume | ~50 % |
| Volatile organic compound (VOC) content | ~138 g/L |
| Abrasion Resistance | ~97 mg (ASTM D4060) CS-17 /1000 g (2.2 lbs.)/1000 cycles |
| Tensile Strength | ~15.5 MPa (~2247 psi) (ASTM D638) |
| Pull-Off Strength | > 2.5 MPa (>363 psi) (substrate failure) (ASTM D7234) |
| Chemical Resistance | Consult Sika® Canada |
| Behaviour after Artificial Weathering | slight yellowing chaulking after 1 week (ASTM G53) 12 weeks (UVB condensation) |
| Resistance to Fire | 6 (FSR) Flame Spread Rating 52 (SDC) Smoke Developed Classification (CAN/ULC S102) |
| Mixing Ratio | A:B = 4:1 by volume |
| Thinner | cold water - maximum 5% by volume Always add the same quantity of water in order to minimize variations in colour and final finish. |
| Product Temperature | Condition product between 18 °C to 24 °C (65 °F to 75 °F) |
| Ambient Air Temperature | Minimum 10 °C (50 °F ) Maximum 30 °C (86 °F) |
| Relative Air Humidity | Maximum 75 % (during application and curing). Sika® Duroplast 150 should not be applied when the ambient air relative humidity is > 75% as curing times will be longer and water will be retained in the film reducing ultimate coating performance. Provide adequate fresh air ventilation to remove the excess moisture from the curing product. |
| Dew Point | Beware of condensation! The substrate must be at least 3 °C (5 °F) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the finish. Be aware that the substrate temperature may be lower than the ambient air temperature. |
| Substrate Temperature | Minimum 10 °C (50 °F ) Maximum 30 °C (86 °F) Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapor drive at the time of application. Refer to ASTM D4263 for a visual indication of vapor drive. |
| Substrate Moisture Content | Maximum moisture content of all concrete substrates must be < 4 % by mass (pbw - part by weight) when measured with a calibrated moisture meter for concrete (Tramex CME/CMExpert). Masonry surfaces, gypsum board and plaster must be below 85 (green zone on the reference scale) when measured with a calibrated electronic moisture meter (Delmhorst Model BD-10). Minimum age of concrete and masonry surfaces prior to application: 28 days (depending on curing and drying conditions). Minimum age of SikaTop® or Sika MonoTop® mortar prior to application: three (3) days, depending on curing and drying conditions. Moisture content must be < 4 % by mass (pbw - parts by weight) when measured with a calibrated moisture meter for concrete (Tramex CME/CMExpert). |
| Pot Life | Material Temperature Time 23 °C (73 °F) ~6 hours (250 g (8.8 oz)) NOTE: Do not apply after six (6) hours even if still liquid, as this will result in lower gloss, loss of chemical resistance and physical properties. |
| Curing Time | Substrate Temperature Touch dry Full Cure 23 °C (73 °F) ~4.5 hours ~7 days Curing times will vary according to air and substrate temperatures and relative humidity. Freshly applied material should be protected from dampness, condensation and water for at least 24 hours. Mechanical, chemical and physical properties will be fully achieved at full cure. |
| Waiting Time / Overcoating | Substrate Temperature Minimum Maximum 23 °C (73 °F) ~6 hours ~48 hours Note: If the Waiting/ Recoat time has passed the previous coat must be lightly sanded, to remove all gloss; vacuum cleaning and solvent wiping will be necessary to remove all traces of dust. The surface should be a uniform dullness, with no gloss present after clean-up and before applying the next coat. |
| Consumption | 6.5 m 2 /L to 9.8 m 2 /L (265 ft 2 /US gal to 400 ft 2 /US gal) per coat (4 to 6 mil w.f.t.) (2 to 3 mil d.f.t.) Typically two coats are required, though on higher absorbency substrates additional coats may be required. Actual coverage rates and material consumption will depend upon porosity and profile of the substrate. Test areas are recommended to establish correct coverage rates. |
| MIXING | Mixing Ratio (A:B) = 4:1 by volume. Do not hand mix Sikagard® Duroplast® resin materials; mechanically mix only. Pre-stir each component separately to ensure that all soft settling is dispersed, solids are evenly distributed and even colours and consistencies are achieved within each component. Empty Component B in the correct mix ratio to Component A into a suitably sized, clean mixing vessel. Mix the combined components for at least three (3) minutes, using a low-speed drill (200 - 300 rpm) fitted with an Exomixer® or Jiffy type mixing paddle suited to the volume of the mixing container, to minimize entrapped air. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once, to ensure complete mixing. When completely mixed, Sika® Duroplast 150 should be uniform in colour and consistency. Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature. |
| APPLICATION | Sika® Duroplast 150 can be applied by brush, roller or spray equipment, whichever is the most suitable to the surfaces to be coated or site conditions and limitations. For spray applications, contact spray equipment specialists to determine suitable equipment and for application advise (thinning maybe required) contact Sika Canada. Sika® Duroplast 150 must be applied in a workman-like manner using skilled and trade qualified applicators. The film thicknesses stated must be produced and complete coverage achieved. After application and prior to drying, remove masking tape in between each coat to avoid ‘ripping’ in the finished coating and let surfaces dry completely. Following cure of body coats, sand off any rough spots and visible defects with a fine sandpaper (120 -220 grit), then vacuum and wipe surface to remove all residual traces of sanding dust before the application of the final top coat. |
| CLEAN UP | Once hardened, product can only be removed mechanically. Clean tools and brushes with Sika® Epoxy Cleaner. |
| Cure time | Substrate Touch dry Full Cure Temperature 23 °C (73 °F) ~4.5 hours ~7 days Curing times will vary according to air and substrate temperatures and relative humidity. Freshly applied material should be protected from dampness, condensation |
| Application temperature | Minimum 10 °C (50 °F ) Maximum 30 °C (86 °F) |
| VOC | ~138 g/L |
| Thinning | cold water - maximum 5% by volume Always add the same quantity of water in order to minimize variations in colour and final finish. |

Full product details, applications & manufacturer specifications
Sika® Duroplast 150 is a two-part, low odour, fine-textured, pigmented, water-based epoxy wall coating.
It produces a glossy durable, easy to clean ceramic-like finish on interior surfaces. Sika® Duroplast 150 demonstrates superior UV resistance to colour change compared to traditional epoxy coatings. Can be applied over properly prepared and primed, concrete masonry, common steel, or gypsum board substrates. It is fully compatible as a system component (body coat and or top coat) in all Sikagard® Duroplast epoxy wall coating systems.
Recommended uses
Typical installation areas include: Hospitals and medical research facilities Pharmaceutical laboratories and production areas Veterinarian and animal holding areas Educational and recreational premises Prisons: holding cells, corridors, and showers Commercial kitchens and service corridors Food and beverage processing areas Packaging and storage areas Rest rooms, locker rooms and showers
