Crystic® Polyester Resin 2.406PA

Chemical Family: Polyesters

Crystic® Polyester Resin 2.406PA is a pre-accelerated, thixotropic, orthophthalic polyester resin with low styrene emission. This laminating resin has rapid wet out and low exotherm, making it ideal for multi-layer laminates in spray or hand-lay applications. It has a 16-minute gel time, Lloyd's approval, and can be used in marine, transportation, building and construction, and industrial applications.

Storage: Crystic 2-406PA should be stored in the dark in suitable closed containers. It is recommended that the storage temperature should be less than 20ºC where practical, but should not exceed 30ºC. Ideally, containers should be opened only immediately prior to use. Where they have to be stored outside, it is recommended that they are kept in a horizontal position to avoid the possible ingress of water.
Additives: The addition of certain pigments, fillers or extra styrene may adversely affect the properties of Crystic 2-406PA. Users should seek advice from our Technical Service Department before making any additions.
Approvals: Crystic 2-406PA is approved by Lloyd's Register of Shipping for the construction of craft under their survey. It also meets the requirements of BS 3532 : 1990 : Type A
PACKAGING: Crystic 2-406PA is supplied in 25kg and 200 kg containers. Bulk supplies can be delivered by road tanker.
Post Curing: Satisfactory laminates for many applications can be made from Crystic 2-406PA by curing at workshop temperature (20ºC). For optimum properties and long term performance, however, laminates should be post cured before being put into service. The laminate should be allowed to cure for 24 hours at 20ºC, and then be oven cured for 3 hours at 80ºC or 16 hours at 40ºC.
