TWEHA 80eight
High-performance hybrid bonding and sealing – indoors and outdoors
TWEHA 80-eight is a powerful, one-component hybrid polymer adhesive and sealant designed for professional bonding, assembly and sealing applications. Its combination of high initial adhesion, flexibility and broad material compatibility makes it a versatile solution for construction, installation and industrial use.
The solvent-free formulation is waterproof, odorless and resistant to mold and bacteria. It cures permanently elastics without shrinkage or cracking and can be painted with most used paint systems. TWEHA 80-eight is suitable for sensitive materials including mirrors and natural stone and does not attack most synthetic materials.
Adhesion to powder-coated surfaces and low-surface-energy materials such as PP, PE, bitumen and silicones should always be tested before application.
