2 It provides bothhydrocarbon and cellulosic fire protection for structuralsteel and can also be used to upgrade the fireresistance of existing concrete. Recommendedareas of application include refineries, petrochemical,pharmaceutical facilities, pulp and paper mills,offshore platforms, nuclear and conventional powerplants, factories, warehouses, institutional andbiomedical Over 35 years of proven performance Exceptional durability and toughness UL 1709 hydrocarbon fire rated up to 4 hours BS 476 hydrocarbon fire rated up to 4 hours ISO 22899-1 jet fire rated up to 2 hours ASTM E119 cellulosic fire rated up to 4 hours Cryogenic protection against LNG spills andimmersion exposures Resistant to 3 bar blast overpressure Hose stream resistant Tolerant to wide range of climates Lightweight one-fifth the weight of concrete forequal fire protection Ideal for onsite and offsite application Easy application by spray or trowel Nonflammable during or after application Chloride and sulfide free no special primingrequired Non-friable high impact strengthColor

The fireproofing should not be consideredas part of the corrosion protection system. Forapplications where primers are required, use aCarboline approved, alkaline resistant 241 must meet minimum UL bond strengthcriteria for contour applications where primers areused. Contact the Carboline Fireproofing TechnicalService for further information and approved Generally not required. In severely corrosiveatmospheres, topcoats may be used for addeddurability and chemical resistance.

4 Consult CarbolineFireproofing Technical Service for selection of thecoating most suitable for the operating Coat In corrosive environments, use anappropriate topcoat. If topcoating is required, applyCarboguard 1340 as a seal coat. Carboguard 1340may be applied after 24 hours of final application ofPyrocrete 241. Consult the Carboguard 1340 ProductData Sheet for minimum and maximum cure Coat Surface hardness should be a minimumShore DO 64 as measured with a durometer prior toSelection & Specification Data application of the topcoat. Normally, this minimum drytime is 10 days at 70 F (21 C) and 40 days at 40 F(4 C), for thickness of 1 ( mm) or For exterior installations, Acrilast caulkshould be applied at all termination joints betweenPyrocrete 241 and the substrate.

Substrates & Surface Preparation General Before applying Pyrocrete 241, the substrate coatingmust be free of all oil, grease, condensation, or If primer is required, steel preparation before primingshould be done in accordance with the recommendedprimer s product data sheet.)

6 Contact CarbolineFireproofing Technical Service for approved Steel Pyrocrete 241 is usually applied directly overgalvanized surface. If priming is required, contactCarboline Fireproofing Technical Service The recommended primer to seal concrete prior toapplying Pyrocrete 241 is Carboguard Aluminum, copper and other non-ferrous metals shallbe primed with one coat of Carboline's &Attachments ( kg/m ) galvanized metal lath, maybe pre-bent and tie-wired into place for appropriatedesign. Optionally, beam furring clips or electricallywelded, pneumatic or self-tapping screws or studs,may be Design - ( kg/m ) galvanizedmetal lath wrapped around the flange edges towardthe web approximately 1 (38 mm). Contour columndesigns allow the use of 2"x 2" ( mm x mm)galvanized or PVC coated hexagonal metal meshwith beam furring clips as an alternate to the ( kg/m ) galvanized metal lath.

7 Plastic-nosedcorner beads may also be used for better thicknesscontrol and aesthetics on flange edges of refer to design details. For contour applicationson structural members with web span greater than16 (406 mm) or flange widths greater than 12 (304mm) refer to the UL Fire Resistance Directory under Coating Materials 241 May 20150148To the best of our knowledge the technical data contained herein is true and accurate on the date of publication and is subject to change without prior notice.

For large webbedmembers, additional support for lath may be neededfor ease of installation. Plastic-nosed corner beadsmay also be used for better thickness control Skirts and Flat Surfaces - Require ( kg/m ) galvanized metal lath beanchored on 12 to 24 (304 mm to 610 mm) centersdepending upon requirements.

9 The lath should overlapand be tie-wired. On tower skirts only, PVC coatedmesh can be used in lieu of ( kg/m )galvanized lath. Mesh shall be 2 x 2 ( mm x ) 20 gauge wire coated with PVC as furnished ram set or welding is prohibited; a pneumaticfastener may be used. On very large areas, controljoints are made by scoring halfway through thethickness of Pyrocrete . This is achieved by using thetrowel blade edge or an appropriate scoring tool. Apreferred option would be the use of plastic-nosedcorner beads. Spacing should be on 10 (3 m) centers,both horizontally and vertically.
