A335

ONE PART WATER-BASED ADHESIVE

PRODUCT INFORMATION

Alpha A335 is a single component sprayable adhesive that provides instant grab and good heat resistant bonding. A335 is sprayable through air assisted equipment free of copper & brass.

It is based on novel water-based dispersion technology that is safe to use. It contains no solvents or isocyanates and conforms to the latest environmental legislation.

Alpha A335 can be used on a variety of substrates to give instant bonds characterised by high strength once fully cured.

KEY INFORMATION

  • Water-based adhesive – safe to use and environmentally friendly

  • Instant hold

  • Ideal for applications involving porous substrates

  • Heat resistance up to 100°C

  • Good adhesion when bonding porous materials to non-porous substrates

TYPICAL APPLICATIONS

Alpha A335 is used in the automotive industry for the production of trim application such as car panels, seats, headrests and headliners.

It can also be used as a general purpose adhesive where high temperature resistance is a preference.

  • Polyurethane and latex foams
  • Leather and leather cloth
  • Fabrics (e.g. Hessian, PVC)
  • Cellulosic substrates (e.g. paper, cardboard, plywood, MDF, chipboard)
  • Metals
  • Plastics (e.g. GRP, ABS)

PRODUCT PERFORMANCE

The performance data presented here has been determined by Alpha Adhesives & Sealants standard test methods and are average values that should not be used for specification purposes. Our recommendations on the use of this product are based on tests believed to be reliable. It is advised that users conduct their own tests to determine the suitability of the product for their specific application.

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 bonded assembly is dependent on the proper surface treatment of the substrates to be bonded . All surfaces of the substrates that are to be bonded should be dry, clean and free from dust, grit, wax, grease or oil.

Mechanical abrasion with sandpaper is advised when using one or more non-porous substrates such as metals, plastics and cured resins. Always ensure that any dust generated from abrasion is cleaned appropriately.

Using a suitable spray delivery system, apply Alpha A335 adhesive to both substrates that are to be bonded. 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 (times according to above instructions). Assemble the bond and consolidate with sufficient 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.

HEALTH & SAFETY INFORMATION

Alpha A335 is not classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha A335 Safety Data Sheet for further health & safety information.

STORAGE

Alpha A335 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 A335 will keep satisfactorily for up to 6 months from date of manufacture if stored according to the recommended conditions.
