HANDLING & APPLICATIONS

The general application information presented here is based upon typical conditions determined by Alpha Adhesives & Sealants Limited 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.

Process Step Guidelines Surface Preparation If bonding to concrete, it should be cured for at least 28 days and have a minimum compressive strength of 25MPa. Clean surface thoroughly to remove all contaminants such as dirt, oil, grease, wax, rust and coatings. All algae and marine growths should be removed prior to application of the grout. Remove laitance and roughen surface to ensure good commercial blast standard by high pressure water blasting or grit blasting.

Adhesive Application 1. Unscrew the cap from the cartridge and remove the plug.

  1. Begin to dispense adhesive.
  2. the nozzle will Mix equal parts of A (white) and B (light brown) until uniform in color (beige).
  3. Apply the mixed Alpha SAS328 adhesive to one of the surfaces to be bonded.
  4. Position the substrates together into the desired final position and clamp together until the handling strength is achieved (approximately 6 hours at room temperature).
  5. Ensure that the cap has been placed and tightly closed.

For application underwater Do not apply in water temperatures below 4°C or above 35°C. Underwater product placement should be attempted only by certified and experienced diving contractors. Curing Handling strength is achieved approximately 6 hours after bonding. Full cure is achieved 24 hours after bonding. Cleaning A suitable solvent cleaner such as Alpha T559 should be used to clean uncured adhesive prior to curing. When fully cured, Alpha SAS328 will require mechanical sanding to remove material.

HEALTH & SAFETY INFORMATION

Alpha SAS328 is classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha SAS328 Safety Data Sheets for further health & safety information.

STORAGE Alpha SAS328 should be stored in its original container, with the syringe cap tightly secured, in dry conditions and at temperatures between -20°C and +35°C. Alpha SAS328 will keep satisfactorily for up to 24 months from date of manufacture if stored according to the recommended conditions.
