Features & Benefits
Applications
DOWSIL™ 3362 Insulating Glass Sealant is intended for use as a secondary sealant in a dual sealed insulating glass unit.
The high performance features incorporated into this product make it specially suitable for the following applications: o Insulating glass units for residential and commercial use. o Insulating glass units with high levels of UV exposure (free edge, greenhouse, etc.). o Insulating glass units incorporating specialty glass types. o Insulating glass units where high heat or humidity may be encountered. o Insulating glass in cold climates. o Insulating glass units used in structural glazing.
How to Use
Mixing and Dispensing Instructions DOWSIL™ 3362 Insulating Glass Sealant should be mixed in a ratio of 10:1 base to curing agent by weight, or equivalent 8:1 by volume for optimal properties. At this mix ratio, the sealant typically exhibits a working time of 5-10 minutes and allows units to be handled within two hours. Slight variations in mixing ratio can be tolerated, but these should not exceed 11:1 to 9:1 by weight or 8.8:1 to 7.2:1 by volume to ensure minimum properties are obtained
Mixing and Dispensing Instructions (Cont.) The sealant is compatible with most DOWSIL™ neutral curing construction sealants. Please contact our technical services department for more information. To obtain the ultimate physical properties from DOWSIL™ 3362 Insulating Glass Sealant, it is recommended that the base and curing agent are thoroughly mixed using an airless mixing system found on most existing commercially available two-part silicone dispensing machines. Catalyst Selection Different catalysts are available for DOWSIL™ 3362 Insulating Glass Sealant:
DOWSIL™ 3362 HV Catalyst is a medium viscosity paste, fast cure, which is suitable for meter mix equipment using a pressure pot or follower plate system for the catalyst.
DOWSIL™ 3362 HV/GER Insulating Glass Catalyst is a viscous paste fast cure and is suitable for meter mix equipment that uses a follower plate system for the catalyst. Equipment Cleaning When not being used it is recommended that the dispensing equipment be purged either with the uncatalyzed base, or flushed with a suitable solvent such as DOWSIL™ 3522 Concentrated Cleaning Solvent. If cured sealant has built up inside the equipment, it is recommended to flush the equipment for the appropriate time with DOWSIL™ 3522 Concentrated Cleaning Solvent. This solvent dissolves cured silicone sealant and provides optimum cleaning performance.
