Product Highlights
  • 4 hardeners (B) give a wide range of processing times
  • Uniform mixing ratio of 100:30 by weight gives even more processing fl exibility
  • Fast infusion and good wet-out of fabrics and non-wovens due to low viscosity and good wetting characteristics
  • All systems are Germanischer Lloyd approved. Certifi cate No. WP 1620019 HH (attached)
  • Particularly good for applications where curing temperatures cannot be >75°C
  • Hardeners (B) Biresin® CH80-1 and CH80-2 can also be used for the manufacture of smaller parts in hand lay-up processing
  • Hardeners (B) Biresin® CH 80-2 and CH 80-6 are also available in blue

Applications & Uses

+
Application

Biresin® CR80 is especially suited to the infusion and injection processes due to its low viscosity range. It can be used in the marine, wind turbine and general industrial composite areas

Processing
  • The material and processing temperatures should be from 18 to 35°C.
  • The mixing ratio must be followed accurately to obtain best results. Deviating from the correct mix ratio will lead to lower performance.
  • The fi nal mechanical and thermal values are dependent on the applied postcuring cycles.
  • To clean brushes or tools immediately Sika Reinigungsmittel 5 is recommended.
  • 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.

  • With hardeners (B) Biresin® CH80-1 and CH80-2 demoulding after room temperature cure is possible.
  • With hardeners (B) Biresin® CH80-6 and CH80-10 curing at 45°C before demoulding is required dependent on components.

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® CR80 resin (A) is 24 month and of hardeners (B) Biresin® CH80-1, CH80-2, CH80-6 and CH80-10 is 12 months 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 at a minimum 60°C.
  • Containers must be closed tightly immediately after use. The residual material needs to be used up as soon as possible
