Metal Weld Black 2-Component Mixture

Description

Metal Weld is a new generation 2-component methylmethacrylate glue which is perfectly suitable for the structural bonding of almost all ferrous and non-ferrous metals as well as a wide range of composite materials.

Its special composition makes Metal Weld particularly suited for easily creating tough, strong adhesive bonds on various (metal) surfaces, such as steel and aluminium. Also on a wide range of composite materials Metal Weld provides, after curing, excellent adhesion with extremely high shear strengths. And all this without prior treatment with a primer!

Metal Weld is extremely resistant to UV, chemicals and the effects of weather, which ensures long-term colourfastness. Attention: too thick layers may cause discolouration due to heat development (recommended layer thickness 0.25 - 0.5 mm). The open time of 8-10 minutes enables to join the parts correctly. Thanks to the thixotropic consistency Metal Weld shows a good stability on vertical parts and thus also an excellent filling capacity.

Metal Weld is very user-friendly and can be dosed very accurately thanks to the handy dual cartridge with mixer nozzle and the use of the Mixer Gun. The special mixer nozzle always ensures the right mixture proportions. After use, this mixer nozzle must be removed and the cartridge must be closed by placing back the cap in its original position.

Properties

• 2-component product for the bonding of almost all ferrous and non-ferrous metals.
• Excellent adhesion.
• Deliverable in white and black.
• Excellent UV and chemical resistance.
• Good temperature resistance.
• Applicable without primer.
• Handy twin cartridge with mixer nozzle allowing easy dosing of the product.
• Isocyanate-free.

Instructions for use

• Surface preparation: The surface must be clean, dry and free of grease. Clean surfaces with Innotec Multisol. Metal Weld can be applied without using a primer. Advice: It is recommended to lightly sand the parts to be glued using non-oxidyzing abrasives.
• Application method: Make sure that all tools needed during the gluing are ready at hand. Screw the mixer nozzle on the twin cartridge. When using a new cartridge, always squeeze out the first 2 centimetres of product and discard it, to ensure a perfect mix of the components. Apply a bead of glue on the parts to be bonded and spread it to a thin, even layer using a spatula. Join the parts together and hold them in position with gluing clamps. Use a spatula to remove any glue squeeze-out. Recommended clamping time: minimum 2 hours (at 20°C). After the removal of the clamps, the repair can be finished. Remove the nozzle after use and close the cartridge by placing back the cap in its original position!
• Remarks: 'Low energy' plastics such as thermoplastics and polyolefins cannot be glued!
