Carboline Pyrocrete 341 - 22.7KG
Carboline Pyrocrete 341 - 22.7KG
Pyrocrete 341 A minimum average 52 lb./ft³ (833 kg/m³) density, portland cement-based fireproofing material that provides hydrocarbon pool fire, jet fire, and cryogenic spill protection for structural steel. Recommended areas of application include refineries, petrochemical, and LNG facilities.
Product Features
- UL 1709 hydrocarbon fire rated up to 4 hours
- ISO 22899-1 jet fire rated from 30 minutes to 2 hours
- ISO 20088-1 cryogenic spill protection to -50°C
- Resistant to 4 bar blast overpressure
- ISO 20088-1 cryogenic spill followed by ISO 22899-1 jet fire
- 4 bar overblast followed by third party witnessed hydrocarbon fire
- NFPA 290 simultaneous torch and hose stream resistant (extended to 150 minutes)
- UL 2431 Category I-A Outdoor Heavy Industrial and Exterior Environmental Purpose
- Lightweight - one-third the weight of concrete
- Ideal for field and shop application
- Enhanced application characteristics (3/4" - 1 1/2" (19 - 38.1 mm) on initial pass)
- Excellent durability with early hardness development
- Non-friable – high impact strength
- Asbestos-free – complies with EPA and OSHA regulations
| Color | Non-Uniform Speckled Gray Product color may vary due to variations in color of Portland cement. |
| Finish | Textured If a smooth finish is required, this may be done by trowel, roller or brush typically within 1 to 2 hours after final application of Pyrocrete 341. |
| Primer | Pyrocrete 341 neither promotes nor prevents corrosion. The fireproofing should not be considered as part of the corrosion protection system. For applications where primers are required, use a Carboline approved, alkaline resistant primer. Contact the Carboline Fireproofing Technical Service for further information and approved primers. |
| Application Thickness | 3/4" - 1 1/2" (19 - 38.1 mm) on initial pass |
| Theoretical Coverage Rates |
14.40 - 13.30 bd.ft/bag @ dry density range of 52 - 55 lb./ft³ (1.34 - 1.24 m2/bag @ range of 833 - 882 kg/m³) Field results will vary depending upon application parameters. Coverage based on theoretical gross yield without loss. Material losses during mixing and application must be taken into account when estimating project requirements. Coverage based on 50 lb. (22.7 kg) bags plus 4.5 gallons (17.0 liters) of water. (one board ft = one ft² of material at one inch thick, or 0.09 m² of material at 25.4 mm thick). |
| Limitations | Not recommended for use as a refractory cement or where continuous operating temperatures exceed 200°F (93°C). |
| Topcoats | Generally not required. In severely corrosive atmospheres, topcoats may be used for added durability and chemical resistance. Consult Carboline Fireproofing Technical Service for selection of the coating most suitable for the operating environment. Seal Coat – In corrosive environments, use an appropriate topcoat. If topcoating is required, apply Carboguard 1340 as a seal coat. Carboguard 1340 shall be thinned 25% with Carboline Thinner 76. Carboguard 1340 may be applied after 24 hours of final application of Pyrocrete 341. Consult the Carboguard 1340 Product Data Sheet for minimum and maximum cure times. Alternatively, the use of Carboguard 1340 WB is an acceptable sealer for Pyrocrete 341. Top Coat – Surface hardness should be a minimum Shore DO 64 as measured with a durometer prior to application of the topcoat. Caulking – For exterior installations, Acrilast Caulk II or approved equivalent should be applied at all termination joints between Pyrocrete 341 and any dissimilar surface. Contact Carboline Fireproofing Technical Service for full information. |
