471PA is a pre-accelerated, low viscosity polyester resin with rapid hardening characteristics. It combines rapid impregnation of reinforcements and fillers with a very short mould release time, and is suitable for hand-lay or spray applications. 471PA is recommended for automotive, marine and resin concrete applications.
471PA is approved by Lloyd’s Register of Shipping for use in the construction of craft under their survey. It also meets the requirements of BS 3532:1990, Type A.
471PA should be allowed to attain workshop temperature (18ºC - 20ºC) before use. It requires only the addition of a catalyst to start the curing reaction. The recommended catalysts are Catalyst M (or Butanox M50) or, where ambient temperatures are high, Catalyst O (or Interox LA3). Either catalyst should be added at 1% or 2% into the resin and thoroughly dispersed.
Full drum quantities of this resin are available with or without catalyst.
Can i use this in a closed mould application?
Yes you can , due to its low viscosity it will flow quite well in a closed RTM tool, it is often used in companies using the 'Prestovac' system due to its low viscosity and short gel time enabling a high turn around of parts.
How much quicker is this compared to your standard Polyester Resin?
Compared to our standard Lloyds approved Polyester Resin:
Crystic 2414 PA , at 15 Deg C with 2% catalyst has a pot life of 43 minutes.
Crystic 471 PA , at 15 Deg C has a pot life of 18 minutes.
So, this resin is has a considerably quicker cure and benefits higher turn around of parts.
