Designed for production of windsurf boards, surfing boards and any transparent top-coating laminate by wet layup methods. Polycraft RSF 816 contains UV filters which give the product a transparent pale violet/blue colour. Although this product contains UV Filters it is still recommended to use with a suitable UV-screening PU varnish, this will reduce the tendency of clear laminates to yellow after prolonged exposure to sunlight.

Cold Weather Notice

Cooler temperatures in the UK and Ireland around mid-autumn to mid spring are not ideal conditions for water clear epoxy systems, this can increase the chances of crystallisation in the resin (this can occur at room temperature depending on circumstances, it is however much less common). Appearance can differ depending on the degree of crystallisation, from small lumps sitting on the surface to a hazy/milky white appearance, extreme cases the contents may completely solidify.  Crystallisation occurs due to a phase change from liquid or solid similar to that of water turning to ice, fortunately it is easily reversed by warming the epoxy component to 60°c.  Ensure any crystals are completely removed as remaining crystals can act as a seed causing the crystals to form again quite quickly. Lab results show the heating cycle to remove crystals can be repeated on multiple occasions before beginning to suffer from any losses in resin properties.   We recommend keeping the resin system at a good room temperature at all times where possible, ensure to clean the lids and bottle necks of containers with isopropyl alcohol / acetone allowing the solvent to evaporate before replacing the lid.
