Product Highlights
  • Flame retardant: UL94 V-0 Classifi cation (see attachment)
  • Choice of hardeners (B) give a wide range of processing times
  • Good impregnation and good non-draining properties due to optimized mixed viscosity for hand lay-up
  • Glass transition temperatures up to 157°C dependent on curing conditions
  • Hardeners (B) are pigmented blue to assist in mixing and to help see where has been laminated

Application

Biresin® CR132 FR is especially suited to the hand lay-up processe and can be used in the general industrial composite and tooling where higher thermal resistance and fi re retardance are needed.

Processing
  • The material and processing temperatures should be in the range 18 - 35°C.
  • The mixing ratio must be followed accurately to obtain best results. Deviating from the correct mix ratio will lead to lower performance.
  • Before demoulding precuring of at least 2 h at 60°C is recommended.
  • The fi nal mechanical and thermal values are dependent on the applied postcuring cycles.
  • It is recommended to clean brushes or tools immediately after use with Sika Reinigungsmittel 5.
  • Additional information is available in “Processing Instructions for Composite Resins”.

Technical Details & Test Data

Postcuring

The suitable cure cycle and the attainable mechanical and thermal values depend on various factors, such as laminate thickness, fi bre volume, reactivity of the resin system etc.
An appropriate cure cycle could look as follows:

  • Heat-up rate of ca. 0.2°C/Minute until approx. 10°C below the required glass transition temperature (Tg)
  • Followed by a dwell at that temperature of between 2 and 12 hours.
  • Part(s) should then be cooled at ~0.5°C per minute

The specifi c postcure should be adapted to the required technical and economic requirements. To measure the mechanical performance of the resin system a SikaAxson standard cycle is used to ensure that the full Tg potential of the system in question is reached.

Storage & Handling

Storage
  • Minimum shelf life of Biresin® CR132 FR resin (A) is 24 month and of Biresin® CH132-2 hardener (B), Biresin® CH132-5 hardener (B), Biresin® CH132-7 and Biresin CH 122-9 hardener (B) is 12 month under room conditions (18 - 25°C), when stored in original unopened containers.
  • After prolonged storage at low temperature, crystallization of resin (A) may occur. This is easily removed by warming up for a suffi cient time at a minimum of 60°C.
  • Containers must be closed tightly immediately after use. The residual material needs to be used up as soon as possible.
