Crystic 489PA is a thixotropic, isophthalic polyester resin. When used with Crystic Gelcoat 65PA, it produces a matched performance system for moulding boat hulls with outstanding durability and superior blister resistance.
The outstanding wetting characteristics of Crystic 489PA gives rapid impregnation with freedom from drainage.
It is suitable for use with continuous rovings, carbon fibres and aramid fibres. Fully cured laminates made with Crystics 489PA have high mechanical and impact properties and excellent strength retention in wet environments at temperatures up to 40ºC. The interlaminar adhesion properties of the resins ensure that no loss in strength occurs at the interface between layers, following any delay in lay-up. Crystic 489PA is tinted blue, to facilitate easier identification and removal of any air trapped in laminates.
Crystics 489 and 489PA are approved by Lloyds Register of Shipping for use in the construction of craft under their survey, and by Det Norske Veritas. They also meet the requirements of B.S.3532:1990, Type B.
