DOWSIL™ 3362 Sealant is a two component neutral curing silicone sealant specifically developed for the manufacture of high performance dual-sealed insulated glass units.

  • Outstanding adhesion to a wide range of substrates including coated and reflective glasses, aluminium and steel spacers, and a variety of plastics.
  • Structural capability as secondary sealant for insulating glass units used in structural glazing.
  • Low water absorption.
  • Excellent temperature stability: -50–150°C.
  • High level of mechanical properties – high modulus.
  • Odourless and non-corrosive cure.
  • Fast curing time.
  • Outstanding resistance to ozone and ultraviolet radiation.
  • Stable viscosity for A&B components; no heating required.

Applications:

  • As a secondary sealant in a dual-sealed insulating glass unit.
  • Residential and commercial use.
  • Insulating glass units with high levels of UV exposure (free edge, greenhouse, etc).
  • Insulating glass units incorporating speciality glass types.
  • Where high heat or humidity may be encountered.
  • In cold climates.
  • In structural glazing.

Standards:

  • When used correctly, manufactured dual sealed insulating glass units meet EN 1279, BS 5713, DIN 1286 and CEKAL requirements.
  • CE marked according to ETAG 002 (ETA 03-0014).
  • Meets sealant requirements according to EN 1279-4 and -6 and pr EN 13022.

Packaging:

  • 3362 Base is available in 250 kg drums and 20 L pails.
  • 3362 Catalyst is available in 25 kg pails.
