WELDYX Professional 15 Black 50 ml – two-component structural MMA adhesive for metals and composites
WELDYX Professional 15 Black 50 ml is a two-component methacrylate (MMA) adhesive designed for structural bonding of metals, plastics and composite materials. It forms strong, flexible bonds, including between materials with different coefficients of thermal expansion.
The adhesive is mixed at a 10:1 volume ratio. Its working time of 25–35 minutes allows sufficient time to apply the adhesive, position the components and adjust their alignment before fixture. The 50 ml cartridge is designed for application using a compatible dispensing gun and static mixing nozzle.
Applications of WELDYX Professional 15 Black
The adhesive is intended for structural bonding in industrial manufacturing, assembly and repair applications, including:
- bonding aluminium and stainless steel,
- bonding selected plastics, including ABS and PVC,
- bonding glass-fibre and carbon-fibre reinforced composites,
- joining metal components with composite materials,
- bonding materials with different coefficients of thermal expansion,
- structural assembly in vehicle manufacturing and industrial equipment production.
When bonding materials with unknown surface characteristics or special coatings, adhesion should be verified on the actual substrates before production use.
Key benefits of WELDYX Professional 15 Black
- MMA adhesive technology – a two-component system for high-strength structural bonding.
- Flexible bond – approximately 100% elongation at break.
- 25–35 minute working time – allows time for positioning and alignment before fixture.
- Gap-filling capability of 0.25–10 mm – suitable for joints with controlled adhesive gaps.
- Adhesion to different substrates – metals, selected plastics and composite materials.
- 10:1 mixing ratio – controlled dispensing with a compatible two-component application system.
- Black bond line – suitable for applications requiring a dark-coloured adhesive joint.
When should you choose WELDYX Professional 15?
This adhesive is worth considering for structural assemblies requiring high bond strength combined with the ability to accommodate deformation and differences in thermal expansion between joined materials.
Professional 15 offers a longer working time than Professional 5, making it suitable for assembly operations requiring additional time for adhesive application, component positioning and alignment.
Important considerations before application
WELDYX Professional 15 Black is not suitable for all plastics. According to the technical documentation, it is not recommended for polyethylene (PE), polypropylene (PP), PTFE or polyoxymethylene (POM). It is also unsuitable for bonding galvanised metals.
Bonding surfaces must be properly prepared. Use a compatible 50 ml cartridge dispensing gun and a static mixer designed for the 10:1 mixing ratio. Observe the specified working time and the time required to achieve final bond strength.

FAQ – Frequently asked questions
Can WELDYX Professional 15 bond aluminium to stainless steel?
Yes. Both materials are included in the manufacturer's stated range of applications. For structural assemblies, bond performance should be verified under actual operating conditions before implementation.
Does WELDYX Professional 15 require a primer?
The manufacturer indicates that many metals and plastics can be bonded without a primer. Final adhesion depends on the substrate, surface coating and surface preparation.
Is WELDYX Professional 15 suitable for polypropylene and polyethylene?
No. Polypropylene (PP) and polyethylene (PE) are among the materials for which the manufacturer does not specify suitable adhesion with this adhesive.
What is the actual working time of WELDYX Professional 15?
According to the technical data sheet, the working time is 25–35 minutes. The name Professional 15 is a product variant designation and should not be interpreted as an exact 15-minute working time.
How long does the adhesive take to reach final strength?
The manufacturer specifies 24 hours to achieve final strength under the test conditions stated in the technical documentation.
Which dispensing gun is required for the 50 ml cartridge?
Application requires a dispensing gun compatible with a 50 ml two-component cartridge with a 10:1 mixing ratio, together with a suitable static mixer. Compatibility with the specific dispensing gun model must be verified before use.
