DOWSIL™ 994 Ultra-Fast Bonding Sealant
Application

Suitable for continuous production processes, automated fabrications and specific bonding designs, e.g.:

  • Structural glazing.
  • Windows and doors bonding.
  • Solar thermal bonding.
  • Internal partition wall bonding.

Description

An ultra-fast, two-part neutral-cure silicone bonding sealant for structural glazing and automated assembly.

Features and benefits:

  • Ultra-fast curing system allowing significant productivity improvements in continuous production processes, automated fabrications and specific bonding designs.
  • Meets European standard for structural glazing (ETAG 002).
  • Suitable for bonding on UV-exposed surfaces due to excellent long term durability and UV resistance.
  • Excellent primer less adhesion to a wide range of substrates.
  • Specially designed for adhesion between glass and polyvinyl chloride (PVC), wood and aluminium window frames.
  • Good adhesion to a wide range of substrates including coated, enamelled and reflective glasses, anodized and polyester paint coated aluminium and stainless steel.
  • High level of mechanical properties.
  • Stable viscosity for base and curing agent.
  • High level of structural capability.
  • High level of movement capability.
  • Odourless and non-corrosive cure.
  • Good stability through wide temperature range: -50°C to +150°C.
  • Fast application with easy-to-use 2-component pumping equipment.
  • Firm cycle time (e.g. window and panel units can be moved along the line within a few minutes).
  • Lot matching of base and curing agent not necessary.
  • European approval for structural glazing.
  • European Technical Approval ETA 18/0571 (colour black).

Applications:

Suitable for continuous production processes, automated fabrications and specific bonding designs, e.g.:
