Carboline Pyrocrete 239 - 22.7KG
Carboline Pyrocrete 239 - 22.7KG
Pyrocrete 239 A medium density, Portland cement based, cementitious fireproofing that is mixed with clean, potable water onsite before application and spray applied to the substrate. It provides 1-4 hour fire protection for structural steel members and upgrades the fire resistance of existing concrete. It can also be used as a thermal barrier over polyurethane foam. Recommended areas of application include pharmaceutical facilities, pulp and paper mills, nuclear and conventional power plants, factories, warehouses, stadiums, institutional and biomedical facilities and acoustical applications.
Product Features
- Combined acoustical and fire protection
- Easily applied by spray or trowel
- Excellent physical properties – hard, durable
- Nonflammable – during or after application
- Asbestos-free – complies with EPA and OSHA regulations
- Chloride and sulfide free – no special priming required
- Non-friable – high impact strength
- Single package – mixed with clean, potable water at the job site
- Investigated for exterior use by Underwriters Laboratories, Inc
- Quality Manufactured – under strict Carboline quality standards
- UL factory inspection service
| 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 239. |
| Primer | Pyrocrete 239 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. Pyrocrete 239 must meet minimum UL bond strength criteria for contour applications where primers are used. Contact the Carboline Fireproofing Technical Service for further information and approved primers. |
| Application Thickness | 1/2-5/8" (12.7-15.9 mm) on initial pass |
| 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 2. Carboguard 1340 may be applied after 24 hours of final application of Pyrocrete 239. Consult the Carboguard 1340 Product Data Sheet for minimum and maximum cure times. Top Coat – Surface hardness should be a minimum Shore DO 35 as measured with a durometer prior to application of the topcoat. Normally, this minimum dry time is 10 days at 70 °F (21 °C) and 40 days at 40 °F (4 °C), for thickness of 1" (25.4 mm) or less. Caulking – For exterior installations a compatible caulk should be applied at all termination joints between Pyrocrete 239 and the substrate. Contact Carboline Fireproofing Technical Service for complete instructions. |
