The improved stability of<strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> <strong>Sealant</strong> atelevated temperatures, UV andhumidity as well as its higher youngmodulus lead to insulated glass unitwithlonger life-time.UV resistance (hours): 5000(NF 85516) CEBTP Report:ref. 2352-9-873Water pick-up (%): 0.5 after 60 dayswater immersion at 60°C (140°F)Penetration index of IG unit:0.027 CEBTP report: ref. 2324-6-658HOW TO USEMixing and dispensinginstructions<strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> <strong>Sealant</strong> shouldbe mixed in a ratio of 10:1 base tocuring agent by weight, or equivalent7.4:1 by volume for optimal properties.At this mix ratio, the sealant typicallyexhibits a working time of5-10 minutes and allows units to behandled within two hours. Slightvariations in mixing ratio can betolerated, but these should not exceed11:1 to 9:1 by weight to ensureminimum properties are obtained.The sealant is compatible with most of<strong>DOW</strong> <strong>CORNING</strong> Neutral CuringConstruction <strong>Sealant</strong>s. Please contactour Technical Services Department formore information.To obtain the ultimate physicalproperties from <strong>DOW</strong> <strong>CORNING</strong><strong>3362</strong> <strong>Sealant</strong> it is recommended thatthe base and curing agent arethoroughly mixed using an airlessmixing system found on most existingcommercially available two-partsilicone dispensing machines.Catalyst selectionDifferent catalysts available for<strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> <strong>Sealant</strong>." <strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> StandardCatalyst is liquid type, longer curetime catalyst suitable for meter mixequipment that uses pressure potsystem." <strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> HV Catalystis a medium viscosity paste, fastcure, which is suitable for meter mixequipment using a pressure pot orfollower plate system for the catalyst." <strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> HV/GERCatalyst is a viscous paste fast cureand is suitable for meter mixequipment that uses a follower platesystem for the catalyst.Base selectionDifferent base grades are available for<strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> <strong>Sealant</strong>." <strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> Standardbase suitable for application wheremedium movement capabilities arerequired." <strong>DOW</strong> <strong>CORNING</strong> <strong>3362</strong> HD basewhen higher modulus and durometerare required for the final elastomer toavoid movement of the primary seal.All base grades are suitable to be usedwithall different catalyst versionsdepending on the different meter mixequipment and curing speedrequirements.Equipment cleaningWhen not being used it isrecommended that the dispensingequipment be purged either with theuncatalyzed base, or flushed with asuitable solvent suchas<strong>DOW</strong> <strong>CORNING</strong> ® 3522 ConcentratedCleaning Solvent. If cured sealant hasbuilt up inside the equipment it isrecommended to flushthe equipmentfor the appropriate time with<strong>DOW</strong> <strong>CORNING</strong> 3522 ConcentratedCleaning Solvent. This solventdissolves cured silicone sealant andprovides optimum cleaningperformance.TECHNICAL SERVICESDow Corning provides comprehensivetechnical service as part of customersupport to ensure the optimalperformance of your insulated glassdesign. This includes dispensingequipment recommendations, as wellas sealant compatibility testing withallyour chosen insulated glass unitcomponents. For structural glazingapplications, special unit design shouldbe reviewed on a project base byDow Corning technical service staff.Consult Dow Corning's TechnicalServices departments for further adviceon specific applications:Dow Corning S.A.Construction Technical ServiceParc IndustrielB-7180 Seneffe - BelgiumTel.: INT +32 (0)64 88 80 00Fax: INT +32 (0)64 88 84 01Dow Corning GmbHRheingaustraße 34, Postfach 130332D-65091 Wiesbaden, GermanyTel.: INT +49 (0)611 - 23 71Fax: INT +49 (0)611 - 237 610Dow Corning Ltd.Meriden Business ParkCopse Drive, Allesley, Coventry,CV5 9RG - United KingdomTel.: INT +44 (0)1676 52 80 00Fax: INT +44 (0)1676 52 81 00HANDLING PRECAUTIONSProduct safety information requiredfor safe use is not included.Before handling, read product andsafety data sheets and container labelsfor safe use, physical and health hazardinformation.
