Features & Benefits

Materials Features
Key Features
  • Crystic® VE671 is more reactive than Crystic® VE676 because of lower molecular weight.
  • It has a lower styrene content and, also, a lower viscosity than Crystic® VE676.

Product Applications

It is suitable for fabrication of fibre reinforced composites by all conventional techniques (contact moulding, filament winding and injection moulding) and for use in many chemical processing industry applications (storage tanks, vessels, ducts).

Properties

Physical Form
Note
  • LPT catalyst should be used in order to reduce the possibility of foam formation. Alternatively, 1–2% of Trigonox 239 with 0.8% Cobalt Octoate (3% Co) can be used.
  • If 1% cobalt is available then an addition of 2.4% will be required.

Technical Details & Test Data

Technical Data

Laminate Construction:Veil/CSM/woven roving/CSM/woven roving/CSM

Post Curing

  • Satisfactory laminates for many applications can be made from Crystic® VE671 by curing at ambient temperature (20°C).
  • For optimum properties and long term performance laminates should be post cured before being put into service.
  • The laminate should be allowed to cure for 24 hours at 20°C and then be oven cured for a minimum of 3 hours at 80°C; the time will be dependent upon the thickness of the laminate.
  • Post curing at 100°C is advisable for high operating temperatures.

Chemical Resistance

  • Crystic® VE671 has excellent chemical resistance to a wide range of substances (acids, alkalis, oxidising agents) at room and elevated temperatures.
  • A separate technical leaflet offers the user a comprehensive guide to the use of Crystic® VE671 based laminates in a wide variety of chemical environments.

Storage & Handling

Storage Conditions
  • Resin should be stored in dark.
  • It is recommended that storage temperature should be less than 20°C, but should not exceed 25°C.
  • In addition, it can be recommended that the vinyl ester resin is weekly aerated with dry and oil free air for 30 minutes through dip pipe
  • (Note: this dip pipe should not contain any zinc or copper alloy). This is done to improve efficiency of inhibitor in order to extend the shelf life of the resin.
