SIKASIL® silicone sealants have been specially developed for difficult applications on glass, metal and natural stone facades. They include Sikasil® SG products for structural glazing, Sikasil® IG for insulating glass units and Sikasil® WS for weatherseals. The professional product range is rounded off with compatible Sika® accessories: spacer tapes, primers, substrate cleaners and machine cleaners. All the products match one another.
Sikasil® weatherseals
Sika offers a new sealant for protecting movement joints against the elements:
Sikasil® for adhesion to facade material
Sikasil® WS-605 S offers exceptional flexibility and excellent adhesion to facade materials; and even non staining properties to glass, metals and some types of natural stone. Another tried and tested weatherseal product is Sikasil® WS-305, which ensures excellent bond strength and weathering resistance. Sikasil® WS-355 is formulated to meet the specific requirements of natural stone facades. This ready-to-use sealant does not stain the edges of natural stone joints and is not corrosive to metals.
Sikasil® for fire-protection
Sikasil® WS-665 is a fire-protection sealant designed for sealing, bonding and repairing applications in the construction sector. This flame-retarding sealant can also be used on alkaline substrates such as concrete and mortar, and is therefore suitable for expansion joints that have to satisfy stringent flame-retardant requirement. Sikasil® WS-665 is characterised by fire restistance for a long duration. A self-leveling version is also available for floor joints.
Sikasil® for glazing applications
Sikasil® WS-621 is the right solution when high mechanical strength is required in total vision glazing (TVG) and other high performance glazing applications.
Structural glazing with Sikasil
For on-site structural glazing applications, Sika offers the one-part silicone sealants Sikasil® SG-18 and Sikasil® SG-20 with high UV and weathering resistance. Sikasil® SG-20 is additionally characterised by extremely high mechanical strength and excellent bonding. Sikasil® SG-500 is preferred for machine application; it is a fast-curing silicone sealant with unrivalled resistance to UV and weathering.
Sikasil® for insulating glass
Sikasil® IG-25 is a two-part silicone sealant developed for bonding multipane insulating glass units in curtain walls. It combines high mechanical strength and good inherent bonding strength with excellent resistance to weathering and UV. With the ultra high modulus secondary sealant Sikasil® IG- 25 HM it is even possible to produce IG units with inert gas filling with a service life of more than 30 years.
