Sikaflex Sealants

Sikaflex and Sikasil sealants are a complete range of one-component and two-component polyurethane and silicone sealants for overhead, vertical and horizontal joint applications, such as expansion joints, window and door perimeters, penetrations and roofing. Proven throughout the years, Sikaflex sealants exhibit many characteristics that offer clear advantages over the competition.

Superior 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.

Sika sealant technology allows sealants to remain flexible after cure to allow for the natural movement of materials, especially during freeze/thaw cycles.

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 your structure.

Substrate Staining
Sikaflex sealants possess an extremely stable consistency and will not stain or discolor virtually any common substrate.

Sikaflex polyurethane sealant scan be treated with most coatings and paints without the risk of delamination.

Water Immersion
Sika polyurethane sealants can be placed in totally immersed environments without debonding or breaking down the integrity of the sealant.

Handling Characteristics
All Sikaflex products are developed with the end user in mind and offer the best application properties on the market including gunning, tooling, tack free time, sag resistance and cut off string.

VOC Compliance
Sika’s unique, low VOC formulations allows the use of our sealants in all states.
