Alpha A 1972 is a single component sprayable adhesive that provides instant bonding with immediate handling strength. It is water-based, contains no solvent or isocyanates and conforms to the latest environmental legislation.
Alpha A 1972 can be used on a variety of substrates to give instant bonds characterised by high strength once fully cured. It has found use in bonding the following substrates: Polyurethane and Latex Foams, Leather and Leather Cloth, Fabrics (e.g. Hessian, PVC), Cellulosic Substrates (e.g. Paper, Cardboard, Plywood, MDF, Chipboard), Metal, Plastics (e.g. GRP, ABS).
General purpose adhesive
Easy to apply
Ideal for applications involving porous substrates
Good adhesion when bonding porous materials to non-porous substrates
Alpha A1972 can be used in the following applications:
- Foam converting for furniture, bedding etc
- Trim adhesive in the automotive industry
- Can be used to bond a variety of substrates including polyurethane & latex foam, textiles, leather, cotton backed PVC, wood and many plastic and metal surfaces.

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.
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.
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.
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.
For wet material, it is advised that any spillages be cleaned up immediately with soapy water before the adhesive can fully dry.
