Adhesives programm


CaTape Uni is an adhesive strip which is adapted for all CaPlast vapour barriers, roofing and façade membranes. The adhesive strip consists of a green LDPE film which is provided with an acrylate adhesive. Application is intended for the overlapping area of the vapour barrier, roofing and underlay membranes. The strip can be used for both interior and exterior applications. When cutting to size a blade of some kind must be used. This prevents the generation of stresses from tearing. In all cases, and especially on wet surfaces, an adhesion test must be carried out. The surface must be sufficiently adhesive, dry and free from dust, grease and ice, for the use. An increased UV exposure is to be avoided.

When working with the material it is necessary to observe the applicable standards, the generally recognized rules of manufacturers as well as the CaPlast laying information. Subject to technical modifications.

Fields of application

• For interior and exterior bonding applications
• For vapour barrier bondings
• Bonding of roofing and underlay membranes
• Bonding of component and roof penetrations


• Very good adhesive properties
• Easy handling
• Solvent - free
• Suitable for standard unwinders
