Eliminates the need for screws or rivets, allowing panels to maintain a clean and seamless architectural appearance.
TWEHA MetalMate
High-performance elastic adhesive for metal and aluminum façade panels
TWEHA MetalMate is a homogeneous, highly elastic, one-component high-end hybrid-polymer adhesive, specially developed for bonding metal façade and wall cladding materials.
TWEHA MetalMate is designed for materials including Aluminium Composite Material (ACM), aluminum, stainless steel, steel, zinc and copper. Its permanent elasticity is particularly important in metal façades, where substantial dimensional movement can occur because of temperature fluctuations and differences in thermal expansion.
Instead of restraining this movement through rigid point fixings, TWEHA MetalMate creates a continuous elastic connection capable of accommodating movement between the metal façade panel and supporting structure.
The complete TWEHA Bonding System combines TWEHA MetalMate, TWEHA Cleaner+ and TWEHA Tape, supplemented where required with products such as TWEHA SyntheticPrimer or TWEHA Prime #1 or TWEHA Blacken. Surface finishes such as powder coatings must always be checked against the applicable TWEHA approval or tested before use. Compatibility must always be verified for the specific supporting structure.

Designed for performance and efficiency
Engineered for reliable bonding


TWEHA MetalMate is particularly suitable for:
TWEHA MetalMate is particularly suitable for Aluminium Composite Material (ACM/ACP) and solid aluminum façade panels, as well as stainless steel panels, steel façade elements, zinc cladding, and copper façade panels. It also performs well with coated and finished metal façade materials, subject to adhesion testing. Ideal for ventilated metal façade constructions — particularly in applications where invisible bonding is preferred over screws or rivets.

Technical questions
Find quick answers to common technical questions about StoneMate.
MetalMate is intended for approved metal façade panels including aluminium, aluminium composite and other suitable metallic materials.
Metal expands and contracts significantly with temperature changes, so the adhesive must absorb movement without creating excessive stress.
Yes. MetalMate is a one-component, moisture-curing elastic hybrid-polymer façade adhesive.
Suitable clean bare or anodised aluminium normally requires correct cleaning rather than an aggressive adhesion primer.
No. Panel dimensions, wind load, thermal movement, bonding length, adhesive geometry and the substructure must all be considered.


More efficient, more economical
Compared to traditional mechanical fixation systems, TWEHA Bonding Systems can reduce installation costs by up to 40%.
Faster installation, fewer components, and no visible fixings result in both economic and aesthetic advantages.
