Two-part silicone sealant for use as secondary sealant in insulating glass units.

Features & Benefits
  • When used correctly, manufactured dual sealed insulating glass units meet EN1279 and CEKAL requirements.
  • Outstanding adhesion to a wide range of substrates including coated and reflective glasses, aluminum and steel spacers, and a variety of plastics.
  • Structural capability as secondary sealant for insulating glass units used in structural glazing.
  • CE Marked according to ETAG 002.
  • Meets sealant requirements according to EN 1279 parts 4 and 6 and EN 13022.
  • Low water absorption.
  • Excellent temperature stability: -50°C to 150°C.
  • Very high modulus which limits the stress on the primary sealant and makes it particularly suited for gas-filled insulating glazing units.
  • Non-corrosive cure.
  • Fast curing time.
  • Outstanding resistance to ozone and ultraviolet (UV) radiation.
  • Stable viscosity for A and B components, no heating required.
Applications
  • DOWSIL® 3362 HD 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 especially suitable for the following applications:
    • Insulating glass units for residential and commercial use.
    • Insulating glass units with high levels of UV exposure (free edge, green house, etc.).
    • Insulating glass units incorporating specialty glass types.
    • Insulating glass units where high heat or humidity may be encountered.
    • Insulating glass in cold climates.
    • Insulating glass units used in structural glazing.
  • Insulating glass units where a high modulus secondary sealant is required, e.g. to limit stress onto the primary sealant for noble gas-filled insulating glazing units.
Typical Properties

DOWSIL® 3362  HD Insulating Glass Sealant has been extensively tested under different type of glass and conditions (air permeability, gas, etc.).

Technical Specifications and Standards

DOWSIL® 3362 HD Insulating Glass Sealant is recommended for use as secondary seal in gas-filled insulating glass units meeting requirements according to EN1279 in an IG system. It is suitable for double and triple IG. As valid for any other technology, a proper application and fabrication of the Insulating glass unit is required.

DOWSIL® 3362 HD sealant has the CE Mark according to ETAG 002. The product also meets sealant requirement according to EN1279 parts 4 and 6.

DOWSIL® 3362 HD sealant has the SNJF Vi-VEC label.

How to Use

Mixing and dispensing instructions 

DOWSIL® 3362 HD Insulating Glass Sealant should be mixed in a ratio of 10:1 base to curing agent by weight. 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 12:1 to 9:1 by weight to ensure minimum properties are obtained. 

The sealant is compatible with most of DOWSIL® Neutral Curing Sealants. Please contact our Technical Services Department for more information. 

To obtain the best mechanical properties from DOWSIL® 3362 HD Insulating 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. 

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 DOWSIL3522 Concentrated Cleaning Solvent. This solvent dissolves cured silicone sealant and provides optimum cleaning performance. 

Technical Services

DOWSIL provides comprehensive technical service as part of customer support to ensure the optimal performance of your insulated glass design. This includes dispensing equipment recommenda-tions, as well as sealant compatibility testing with all your chosen insulated glass unit components. For structural glazing applications, special unit design should be reviewed on a project basis by Dow Corning technical service staff.
