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.
All substrate surfaces should be abraded using abrasion paper or air-driven narrow belt sander. It is imperative that the surfaces are then cleaned of any dust, grit, loose material, wax, grease and oil using a suitable cleaner such as Alpha T559.
- Mix 1 part of SAS 526 Part A with 1 part of SAS 526 Part B in a clean container until a uniform consistency is achieved.
- Apply the mixed SAS526 adhesive to one of the surfaces to be bonded. This must be done before pot life is exceeded.
- Position the substrates together into the desired final position and clamp together until the handling strength is achieved (approximately 6 hours at room temperature).
Heat can be applied to speed up the rate of cure of SAS526 and will result in a tougher cured product. Approximate times for heat curing are:
- 75°C – 60 minutes
- 100°C – 20 minutes
Handling strength is achieved approximately 6 hours after bonding. Full cure is achieved 24 hours after bonding.
A suitable solvent cleaner such as Alpha T559 should be used to clean uncured adhesive prior to curing.
When fully cured, Alpha SAS 526 will require mechanical sanding to remove material.
HEALTHY & SAFETY INFORMATION
Alpha SAS526 is classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha SAS526 Safety Data Sheets for further health & safety information.
Alpha SAS526 should be stored in its original container, with the syringe cap tightly secured, in dry conditions and at temperatures between 5°C and +25°C. Alpha SAS526 will keep satisfactorily for up to 24 months from date of manufacture if stored according to the recommended conditions.
