Supex M1525 Structural MMA adhesive

Product Description

Supex M1525 is a two-component structural methacrylate adhesive, designed for the bonding of high-strength metal and composite applications in the automotive industry. Supex M1525 has been formulated from innovative technology, including our revolutionary adhesion system. This unique system enables Supex M1525 to achieve the ultimate balance of mechanical strength and impact resistance whilst still remaining both simple and quick to use.

Typical Applications

Supex M1525 is highly versatile and can bond a wide variety of substrates without the need for surface primers or conditioners. Typical examples include:

• Bonding metal fasteners to moulded composite parts
• Bonding and repairing caravan GRP body panels
• Bonding and repairing plastic bumpers and trims
• Bonding deck fittings and moulded parts in the marine industry

Instructions For Use

1. Always consult the MSDS before using Supex M1525 for the first time.
2. Carry out surface preparation where required.*
3. Remove the cap and attach the mixer nozzle.
4. Dispense sufficient adhesive to ensure equal mixing.
5. Apply adhesive to one surface and assemble components carefully, clamping if required.
6. It is always easier to remove any excess adhesive prior to cure using a suitable cleaner.*
7. Allow the adhesive sufficient time to achieve handling strength before moving or unclamping components.
