Application

For professional use only. Used in highly demanding industrial applications such as:

  • Structural glazing applications in tall landmark buildings where high dynamic forces act on the facade.
  • Blast resistant glazing.

Consult manufacturer for information regarding suitable preparation and application methods for this product.

Description

Two-part, high modulus, neutral-curing structural silicone adhesive with an extremely high mechanical strength. It is mainly used for structural glazing applications and is well suited wherever in structural bonding higher mechanical strength is required. It conforms with the requirements of EOTA ETAG 002. It is a CE-marked product.

Features and benefits:

  • Offers a high degree of mechanical strength, which allows for slimmer frames and larger glass areas.
  • Bonds well to a wide variety of substrates.
  • Meets requirements of EOTA ETAG 002 (carries ETA), EN 15434, ASTM C 1184 and ASTM C 920 (class 12.5, movement capability ± 12.5 %) Structural Sealant Glazing Kit: Structural Sealant according ETAG 002 Part 1 Edition November 1999 (Revised March 2012) used as EAD, ETA-11/0392 issued by Technical Assessment Body Österreichisches Institut für Bautechnik, Declaration of Performance 60241468, certified by notified product certification body 0757, certificate of constancy of performance 0757-CPR-596-7110761-5-2, and provided with the CE marking
  • High design tensile strength for dynamic loads: σdes = 0.20 MPa (ETA).
  • SNJF-VEC recognized (product code: 3741).

Applications:

For professional use only. Used in highly demanding industrial applications such as:
