ALPHA 132

MOISTURE-CURE POLYURETHANE SEALANT

PRODUCT INFORMATION

Alpha 132 is a high performance flexible polyurethane (PU) adhesive/sealant that is ideal for a wide range of automotive, marine and aerospace applications. The adhesive sealant creates a very strong bond between a range of materials such as carbon fibre, metals, GRP, plastics and rubbers.

Alpha 132 is a single part, moisture-cure adhesive/sealant that requires no mixing or activating. It is available in white, grey and black, allowing the user a choice of colour to match the materials they wish to bond together for a more aesthetic bond.

 

It is particularly effective as an adhesive in applications where vibration is likely to occur (such as on a car, truck, boat, plane etc.) owing to its flexibility. Its excellent weathering resistance properties make it ideal for conditions where wide ranges of temperature, humidity, water (including saltwater) or UV exposure might be present.

  • Automotive industry (car body assembly, buses, containers etc.)
  • Vehicle conversion, caravans.
  • Window and door frame perimeter joints.
  • Construction and building joints including floor and concrete joints.
  • Bonding applications in metal constructions and for mounting vibrating parts.

PRODUCT CHARACTERISTICS

The following technical information and data should be considered representative or typical only. Therefore, the information should not be used for specification purpose.

*This time is shorter when temperature and relative humidity are higher. It is absolutely necessary to make sure that open time is not excessive. Otherwise, defective bonding could happen.

HANDLING & APPLICATIONS

The general  application  information  presented  here is  based  upon  typical conditions determined by Alpha Adhesives & Sealants Limited’s own 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 cleaned of any dust, grit, loose material, wax, grease and oil using Alpha Cleaner T559 TF.

Application Method:

  1. Joint edges should be protected using masking tape.
  2. Cut the tip of the nozzle at a 45° angle to give a slightly larger hole than the gap that has to be filled.
  3. Alpha 132 can be applied by a pneumatic or hand gun under a uniform pressure to extrude a continuous smooth bead.
  4. After application, the sealant can be finished by using a wet spatula. The tape should be removed as soon as possible before formation of a skin.

The rate of cure in the joint is dependent on the ambient conditions, the assembled joint arrangement and the depth of the sealant between the joint faces.

Clean tools immediately after use with Alpha Cleaner T559 TF. Clean hands with a proprietary hand cleaner.

HEALTHY & SAFETY INFORMATION

Alpha 132 is classified as hazardous according to Directive EC 1272/2008. Please refer to the Alpha 132  Safety Data Sheet for further health & safety information.
