Application

Particularly suitable for structural glazing and other bonding applications where high mechanical strength with silicone is required.  For professional use only.

Description

Sikasil® SG-550 is a two component, neutral-curing structural silicone adhesive with very 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 complies with EOTA ETAG 002 and is a CE-marked product.


Features and benefits:

  • High mechanical strength.
  • Outstanding UV and weathering resistance.
  • High design tensile strength for dynamic loads: σdes = 0.20 MPa (ETA).
  • SNJF-VEC recognized (product code: 3741).
  • Meets requirements of EOTA ETAG 002 (carries ETA), EN 15434, ASTM C1184 and ASTM C920 (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-596-7110760-5-4, and provided with the CE marking.
  • Snap time (CQP 554-1): 30 minutes (23°C/ 50% r.h.).
  • Tack-free time (CQP 019-3): ~150 minutes (23°C/ 50% r.h.).
  • 100% modulus (CQP 036-1/ ISO 527): 1.7 MPa.
