Composite Materials Features
Product Highlights
  • Fast wetting of dry fabrics and nonwovens is possible due to optimized mixed viscosity
  • Glass transition temperatures up to and above 130°C
  • 3 hardeners (B) give a wide range of processing times

Applications & Uses

+
Application

Biresin® CR131 is especially suited to the infusion or injection processes and can be used in general industrial composites and in tooling where higher thermal resistance is 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”.

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® CR131 resin (A) is 24 month and of hardeners (B), Biresin® CH135-4, CH132- 5 and CH132-7 is 12 month under room conditions (18 - 25°C), when stored in original unopened containers.
  • After prolonged storage at low temperature, crystallisation of resin (A) may occur. This is easily removed by warming up for a suffi cient time to 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.
