- Typical Applications
Alpha A406 can be used in the following applications:
- Automotive industry for the production of trim application such as car panels, seats, headrests and headliners.
- Marine industry for trimming applications on a wide variety of fabrics to wood, metal and composite materials.
- Bonding foam-based insulation panels to plasterboard.
- It can also be used as a general purpose adhesive where high temperature resistance is a preference.
- Handling & Applications
The general application information presented here is based upon typical conditions determined by Alpha Adhesives & Sealants testing. Our recommendations on the use of this product are based on methods believed to be reliable. It is advised that users conduct their own tests to determine the suitability of the product for their specific application.
Surface Preparation
Mechanical abrasion is advised when using non-porous substrates such as metals, plastics etc. All surfaces to be bonded should be dry, clean and free from dust, grit, wax, grease or oil.
Adhesive Application
Using a suitable spray delivery system, apply an even coat of Alpha A406 adhesive to both substrates that are to be bonded. Ensure that spray equipment is free of copper and brass pipework or fittings.
- Non-porous substrates (e.g. metal, plastics) – two to three thin layers should be applied, allowing 10 to 15 minutes in between coats.
- Porous substrates (e.g. wood, leather) – two to three layers should be applied, allowing 5 to 10 minutes in between coats.
Allow the final coat to achieve a touch dry state. Assemble the bond and consolidate with pressure to assure a good contact across the bond line. The use of a nip-roller is recommended for ensuring optimum contact is achieved across the bonded area.
Curing
The bonded assemblies will have enough strength for moving, machining and trimming within 15 minutes depending upon the porosity of the substrates. Bonded assemblies should be left for 7 days before physical testing is conducted.
Cleaning
For wet material, it is advised that any spillages be cleaned up immediately with soapy water before the adhesive can fully dry.
