Statistics
- Temperatures of reaction and foam generation proceed between >250°C and 350°C, well below the thermal stress point of steel, but adequately above ambient conditions, therefore providing stability to the formulation.
- The four factors evaluated were levels of pentaerythritol, melamine, ammonium polyphosphate, and TiO2. These levels were balanced to maintain a consistent PVC of 78-80%.
- Even with less than traditionally applied film thickness, samples were observed to reach 500°C on the backside of the steel at nearly twice the time.
- Intumescent foam can attain a thickness 10 to 100 times the originally applied coating, and insulates the substrate material through its low thermal conductivity.
- Fire-resistant times of 120 min can be easily achieved using Exolit AP 435 (dry film thickness, DFT = 2000 μm). In addition, there is no influence on the fire protection performance observed when Exolit AP 422 is replaced by Exolit AP 435.
- The coating cures at ambient temperature, is dryto- touch after 4 hrs and scratch resistant after 24 hrs.
- When tested in a cone calorimeter test (iCone; 50 kW; distance 25 mm) on a pine wood substrate (400 g/m² wet) the intumescent coating shows outstanding fire protection performance.
- Intumescent coatings generally cost $4 to $12 per square foot.
- The coating has a white color and a smooth or matte finish. It contains 54 ± 2% volume solids (ASTM D2697) and 66 ± 2% solids by weight. The specific gravity is 1.35 ± 0.05.
- The theoretical spreading rate of the coating is between 2.70 m²/L and 1.80 m²/L. The recommended dry film thickness (DFT) is between 200 and 300 microns per coat, while the recommended wet film thickness (WFT) is between 370 and 555 microns per coat.
- The paint will be touch dry within 2 to 4 hours, ready for recoating after 24 hours, and will achieve full hardness and cure within 36 hours.
- A range of clear and white intumescent fire-resistant paint for wood. Giving protection to various wood and wood-derived materials. Ideal for painting or upgrading existing wood or timber surfaces to either 30 or 60 minutes of fire protection.
- Hempacore intumescent fire protective coatings can be used on a wide range of structures, from sports stadia and transportation centres to buildings and skyscrapers.
- They can be specified for 30, 60, 90 or 120 minutes, and the range includes Hempacore AQ, a waterborne VOC-free coating that complies with the latest environmental standards for green buildings.
- Thin-film intumescents are typically single component solvent or waterbased products, and have dry film thicknesses (DFTs) of less than 5 millimetres.
- Thick-film coatings are typically solvent-free, epoxy-based with DFTs of up to 25 millimetres.
