Universal silicone sealant Sikasil Universal from Sika

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.)
