Crystic Fireguard 73PA is a pre-accelerated filled brush gelcoat. It is available in a wide range of colours and the information contained in this technical data sheet also applies to these pigmented versions.

Crystic Fireguard 73PA can be used both internally and externally for building, transport and general industrial work.

Features and Benefits
Crystic Fireguard 73PA has very low flammability.

Crystic Fireguard 73PA should be allowed to attain workshop temperature (18°C-20°C) before use. Stir well by hand or with a low shear stirrer to avoid aeration and then allow to stand to regain thixotropy. Crystic Fireguard 73PA 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 gelcoat. (Please consult our Technical Service Department if other catalysts are to be used). The catalyst should be thoroughly incorporated into the gelcoat, with a low shear mechanical stirrer where possible.

For normal moulding, the application of Crystic Fireguard 73PA should be controlled to 0.4 - 0.5mm (0.015 - 0.020 inch) wet film thickness. As a guide, approximately 550-750g/m² of gelcoat mixture (depending on pigment) will give the required thickness when evenly applied.

The addition of fillers or pigments to Crystic Fireguard 73PA is likely to affect the weathering and cure of this material and is not recommended.

Recommended Testing
It is recommended that customers test Crystic Fireguard 73PA before use under their own conditions of application to ensure the required surface finish is achieved.

Physical Data - Uncured
The following tables give typical properties of Crystic Fireguard 73PA when tested in accordance with SB, BS EN or BS EN ISO test methods.

For many applications, Crystic Fireguard 73PA will perform adequately when cured at workshop temperature (20°C). However, for optimum properties it should be allowed to cure for 24 hours at 20°C, and then be oven-cured for 3 hours at 80°C.

Crystic Fireguard 73PA should be stored in its original container and out of direct sunlight. 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.

For further information please read technical data sheet.

Please note - Polyester gelcoats are best used within six months from date of purchase.
