UV Solar Cure Polyester Surfboard Resin
UV Solar Cure poly resin contains a curing catalyst that is activated by UV rays from the sun or ultra-violet bulbs. Water clear polyester resin cures in about 3 minutes when exposed to sunlight. Take as much time as you need to laminate and hotcoat in a shaded area and bring the board into the sunlight to cure.
- You must add Surfacing Wax for hotcoats and glosscoats.
- For fin box and leashplug installation, and when working with color resin tints and pigments, use MEKP Catalyst for curing the resin since UV rays will not completely penetrate the resin in those situations. You can use 1% MEKP in the UV resin to give you more time to laminate.
Save money and simply add Surfacing Wax to make your own hotcoat/sanding resin and gloss resin (+Styrene). No need to buy a separate gallon of poly sanding or gloss resin that will go bad in a short time!
How to successfully hotcoat with UV Sun Cure resin:
Mix surfacing wax with the UV cure resin and hotcoat as normal. "Flash" the hotcoat in the sun for about 10 second to initiate the cure and bring back inside for 10 minutes to let the wax rise to the top and harden. Then put the board back in the sun for 3 minutes to fully cure your hotcoat.
If you do not "flash" the hotcoat and cure the resin before the wax rises it will remain sticky and not be sandable.
*Polyester resin has a 6 month shelf life. Please use the resin within 5 months of purchase to be sure it it fresh.
