Crystic White Topcoat 65PAX 337 is a pre-accelerated, isophthalic Topcoat. It has been formulated for brush application.
Crystic White Topcoat 65PAX is designed for use where a smooth finish is required on the reverse side of a laminate.
Crystic White Topcoat 65PAX should be allowed to attain workshop temperature (18ºC-20°C) before use. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy. Crystic Topcoat 65PAX requires only the addition of catalyst to start the curing reaction. The recommended catalyst is a Medium Reactivity MEKP (or other equivalent catalyst), which should be added at 2% into the topcoat. The catalyst should be thoroughly incorporated into the Topcoat, with a low shear mechanical stirrer where possible..
For normal moulding, the application of Crystic Topcoat 65PAX should be controlled to 0.4-0.5 mm (0.015-0.020 inch) wet film thickness. As a guide, approximately 450-600 g/m2 of Topcoat mixture (depending on colour) will give the required thickness when evenly applied. Crystic Topcoat 65PAX is not suitable for use on parts which will be continually immersed in water, e.g. boat hull.
