WELDYX MASTER WHITE is a high-performance adhesive for structural bonding of metals, composites and plastics. This two-component methyl methacrylate adhesive, mixed in a 10:1 ratio, is available with processing time of 5, 10 and 15 minutes. WELDYX MASTER WHITE allows to achieve high-strength and at the same time flexible and highly resistant structural bonds.

Its product properties are specially tailored to the requirements of industrial applications. These properties have also been confirmed by a product analysis carried out by the Instytut Kolenjnictwa, Warsaw. Thanks to testing in accordance with DIN EN 45545-2/R1 and fulfilment of the HAZARD LEVEL HL 3 fire protection level, WELDYX MASTER 15 WHITE meets the requirements for rail vehicles with a high hazard class.

 Due to its flexibility, even materials with different coefficients of thermal expansion can be successfully bonded. Compared to other adhesives, WELDYX MASTER WHITE is characterised with low shrinkage behaviour and is available with two reaction times which enable the user to achieve precise bonding within the desired time. The use of primers is not necessary which saves time and costs.
