White Crystic 2.446PALV Lloyds Approved Resin by Scott Bader. Used primarily to reduce Print Through on Moulds or Mouldings. Aslso used with a last laminate layer before using a very light coloured Final Topcoat.
This Resin is a pre-accelerated, thixotropic low viscosity polyester resin with low styrene emission. Its rapid wet-out, low exotherm and fast hardening characteristics make it ideal for applications which require a fast mould turn round.
This resin is widely used in the Boat Building and Composite Manufacturing Industries. It is also used in the Fibreglass Flat Roofing Industry.
NB - No Catalyst Included in the 225kg and 1100kg size Resins.
Crystic 2-446PALV is approved by Det - Norske Veritas and by Lloyd’s Register of Shipping for use in the construction of craft under their survey.
Used in conjunction with Chopped Strand Matting, Woven Fabrics and Biaxual Mattings.
A colour change mechanism is incorporated into Crystic 2-446PALV and its variants, to indicate the presence of catalyst. After catalyst addition, the resins will change from blue to green, then to a yellowish colour, before gelation. The recommended catalyst is Catalyst M (or Butanox M50) which should be added at 1% or 2% into the resin. The approximate pot life of Crystic 2-446PA at a temperature of 20 degrees using 1% catalyst addition is 35 mins
