Process Step

Guidelines

Surface Preparation

The strength and durability of the bond is dependent on proper surface treatment of the materials to be bonded. Mechanical abrasion with sandpaper 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

Mix well before use.

Using a suitable spray delivery system, apply Alpha A1972 adhesive to both substrates that are to be bonded. Ensure that air assisted spray equipment is free of copper and brass pipework or fittings.

Ensure that an even coat is applied in all cases.

For non-porous substrates (e.g. metal, plastics) – two to three thin layers should be applied, allowing 10 to 15 minutes in between coats.
For porous substrates (e.g. wood, leather) – two to three layers should be applied, allowing a shorter time period (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 preferred 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.

HEALTH & SAFETY INFORMATION

Alpha A1972 is not classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha A1972 Safety Data Sheet for further health & safety information.

STORAGE

Alpha A1972 should be stored in its original container, with the lid tightly secured, in dry conditions and at temperatures between 5°C and 25°C. Alpha A1972 will keep satisfactorily for up to 12 weeks from date of manufacture if stored according to the recommended conditions.
