SikaSil Silicone Sealants |
Proven over the years, Sikaflex Polyurethane is the product of choice in a wide range of construction applications, Polyurethanes exhibit many characteristics that offer advantages in certain applications.
These characteristics are:
|
|
SikaSil silicone is the product of choice when specific characteristics are desired in a sealant. Typical conditions favoring selection of SikaSil silicone sealants occur in glass to glass and glass to metal interface in glazing systems.
Important characteristics include:
|
Adhesion:
Sikaflex sealants will bond to more surfaces, particularly porous substrates such as concrete and masonry, without the use of primer. It is an accepted fact that Sikaflex polyurethanes have superior wetting action in achieving a bond to various substrates under jobsite conditions.
Dirt resistance:
Because of their exclusive chemical design, Sikaflex sealants exhibit far less dust and dirt pick-up during cure and over the lifetime of the building.
Substrate staining:
Sikaflex sealants possess an extremely stable consistency and will not stain or discolor virtually on any common substrate.
Paintability:
Sikaflex sealants can be treated with most coatings and paints without the risk of delamination.
Water immersion:
Many Sikaflex sealants can be placed in totally immersed environments without being affected by the action of the water.
|
|
Adhesion:
Excellent adhesion to glass including conditions subjecting sealant to reflected UV radiation at the bond line.
Color retention:
White and other light colors will not yellow with age. Therefore white remains white.
Heat resistance:
Applications subjecting sealant to unusually high temperatures can often be sealed with SikaSil silicone sealant.

Waterproofing
|
|
|
Sika has a wide range of products designed to make concrete and masonry impermeable to water. This is important for liquid containing structures, such as reservoirs, for keeping the water in and for other structures, such as foundations and basements, for keeping the water out. In addition, Sika offers special sealing systems to waterproof the critical areas, such as joints and cracks, where water can penetrate if not addressed.
Some of the products and systems offered by Sika include:
- Waterproofing admixtures
- Waterproofing renderings
- Joint sealing systems
- Crack injection resins
- Protective coatings
- Sikadur Combiflex for repairing difficult joints
- SikaSwell for new construction joints
