Description
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:
Adhesion
Sikaflex polyurethane sealants will bond to more surfaces, particularly porous substrates such as concrete and masonry, without the use of a primer. It is an accepted fact that Sikaflex polyurethane sealants have superior wetting action in achieving a bond to various joint substrates under jobsite conditions.
Substrate Staining
Sikaflex polyurethane sealants possess an extremely stable consistency and will not stain or discolor virtually any common substrate.
Water Immersion
Many Sikaflex polyurethane sealants can be placed in totally immersed environments without being affected by the action of the water.
Dirt Resistance
Because of their exclusive chemical design, Sikaflex polyurethane sealants exhibit far less dust and dirt pick-up during cure and over the lifetime of the building.
Paintability
Sikaflex polyurethane sealants can be treated with most coatings and paints without the risk of delamination.
