Post CuringSatisfactory laminates for many applications can be made from Crystics 489 and 489PA by curing at workshoptemperature (20ºC). For optimum properties and long term performance, however, laminates should be post curedbefore being put into service. The laminate should be allowed to cure for 24 hours at 20ºC and then be oven cured for 3hours at 80ºC or 16 hours at 40ºC.Typical PropertiesThe following tables give typical properties of Crystics 489 and 489PA when tested in accordance withBS 2782.Liquid ResinProperty 489 489PAAppearance Blue BlueViscosity at 25ºC 37.35 sec -1 poise 7.3 4.4Viscosity at 25ºC 4500 sec -1 poise 3.3 2.5Specific Gravity at 25ºC 1.10 1.11Volatile Content % 42 43Acid Value mg KOH/g 19 18Stability in the dark at 20ºC months 6 3Geltime at 25ºC using 1% Catalyst M(or Butanox M50)Geltime at 25ºC using 2% Catalyst M and4% Accelerator Eminutes - 23minutes 8 -Fully Cured* Resin(unfilled casting)Property 489 489PABarcol Hardness (Model GYZJ 934-1) 46 44Deflection Temperature under load †(1.80 MPa)ºC 80 77Water Absorption 24 hours at 23ºC mg 18 17Tensile Strength MPa 80 76Tensile Modulus MPa 3600 3500Elongation at Break % 4.3 4.0Specific Gravity at 25ºC 1.21 1.20Volumetric Shrinkage % 7.7 7.7Property* Curing Schedule - 24 hrs at 20ºC, 3 hrs at 80ºC† Curing Schedule - 24 hrs at 20ºC, 5 hrs at 80ºC, 3 hrs at 120ºCC.S.M** Laminate489 489PAGlass Content % 32.0 31.8Tensile Strength MPa 130 128Tensile Modulus MPa 7800 7700Elongation at Break % 2.0 2.1Flexural Strength MPa 214 212Flexural Modulus MPa 7500 7400** Made with 4 layers 450g/m 2 PB CSMCuring schedule - 24hrs at 20ºC, 16hrs at 40ºCCrystic 489 and Crystic 489PA - TDS 2/3
StorageCrystics 489 and 489PA should be stored in the dark in suitable closed containers. It is recommended that the storagetemperature should be less than 20ºC where practical, but should not exceed 30ºC. Ideally, containers should be openedonly immediately prior to use.PackagingCrystics 489 and 489PA are supplied in 25kg and 200kg containers. Bulk supplies can be delivered by road tanker.Health & SafetyPlease see separate Material Safety Data Sheet.Technical Leaflet No. 172.5Version 2 : February 2013All information on this data sheet is based on laboratory testing and is not intended for design purposes.
