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.

Water immersion:

Many Sikaflex sealants can be placed in totally immersed environments without being affected by the action of the water.
Adhesion:
