Multi-Material Bonding

Find the TWEHA bonding system developed specifically for your substrate — engineered for strong adhesion and long-term façade performance.

TWEHA 20two

TWEHA 20-two is a high-quality, exceptionally weather-resistant and durable polysiloxane-based sealant, specially developed for professional glazing, curtain wall and façade applications.

Thanks to its permanent elastic properties and extremely high movement capability, TWEHA 20two provides a reliable and durable seal for joints exposed to movement, changing temperatures and demanding weather conditions. The sealant is easy to apply, even at low temperatures, and shows minimal stringing during application.

TWEHA 20-two is the professional choice where maximum elasticity, weather resistance and long-lasting sealing performance are essential.

TWEHA 80eight

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.

TWEHA 90nine

TWEHA 90-nine is an innovative, low-viscosity one-component MS Hybrid polymer adhesive and sealant, specifically developed for sprayable and brush able applications. It combines efficient application with permanent elasticity and a broad adhesion spectrum, making it ideal for larger surfaces and demanding construction and industrial applications.

The moisture-curing formulation is solvent-, isocyanate- and silicone-free, odorless and non-corrosive to metals. After curing, TWEHA 90-nine forms a durable, flexible and weather-resistant layer with excellent resistance to moisture, UV exposure, ageing and mechanical vibration.

Highly porous substrates should be pre-treated with TWEHA PreFix X-tra. All surfaces must be clean, stable, grease- and dust-free before application.
