Description

General purpose sealing silicone Sikasil Universal

Sikasil Universal is suitable for sealing glazing and sealing with environmental ageing resistance requirements on non-porous substrates such as glass and glazed ceramic tiles

Benefits

  • Low modulus of elasticity
  • High elasticity and flexibility
  • Very good resistance to shrinkage, cracking and discolouration
  • Very good adhesion to a wide range of non-porous substrates

Characteristics

  • Composition Acetoxy (acetate) silicone
  • Density ~ 1,0 kg/l
  • Shore A hardness ~ 20 (after 28 days)
  • Tensile strength ~ 1,7 N/mm2
  • Modulus of elastic deformation ~ 0,35 N/mm2 at 100% elongation (23 °C)
  • Elastic recovery > 90%
  • Tear propagation resistance ~ 1,9 N/mm
  • Mobility ± 20%
  • Operating temperature -40 °C to +100 °C

Application

  • The substrate must be clean, dry, stable, homogeneous, free from grease, dust and loose parts. Paints, cement laitance and other materials with low adhesion should be removed.
  • Sikasil Universal is adhered without primers and/or activators. However, for optimum adhesion and in critical applications, e.g. applications in high-rise buildings, high-stress welds, in cases of exposure to extreme weather conditions or immersion in water, the following priming and/or substrate preparation procedures should be used:
    • Aluminum, anodized aluminum, stainless steel, galvanized steel, electrostatically painted metals or glazed tiles should be cleaned and prepared with Sika Aktivator-205 applied to a clean cloth. Before sealing, allow a drying time of > 15 minutes (< 6 hours).
    • Other metals such as copper, brass and titanium-zinc should also be cleaned and prepared with Sika Aktivator-205 applied to a clean cloth. After the drying time has been observed, apply Sika Primer-3 N with a brush and observe an additional additional drying time of > 30 minutes (< 8 hours) before sealing. Glass substrates should be cleaned with isopropyl alcohol prior to application.
  • Curing flow Ambient temperature +5 °C to +40 °C, at least 3 °C above dew point
  • Substrate temperature +5 °C to +40 °C
  • Cure rate ~ 3,0 mm/24 hours (23 °C / 50% S.H.)
  • Cuticle formation time ~ 15 minutes (23 °C / 50 % S.W.)
