Crystic 2-446PA Unpigmented (Clear) General Purpose Laminating Polyester Resin (Lloyd's approved, Low styrene emission) Pre-accelerated, thixotropic viscosity polyester resin with low styrene emission.  Its rapid wet-out, low exotherm and fast hardening characteristics make it ideal for spray applications which require a fast mould turn round.  This reduction in styrene emission is achieved with no loss of interlaminar adhesion.
Approved by Det-Norske Veritas and Lloyd's Register of Shipping for use in construction of craft under their survey.
Crystic 2-446pa should be allowed to attain workshop temperatures (18°c - 20°c) before use.  They need only the addition of a catalyst to start the curing reaction.  A colour change mechanism is incorporated into Crystic 2-446pa to indicate the presence of catalyst. After catalyst addition the resin will change from a blue-ish translucent to a brown-ish tone indicating catalysation.  (typical colour of laminate will vary from a yellow to green tone depending on the type of reinforcement and amount of layers used in most cases.   Catalyst should be added at 1% or 2% into the resin.
