Why we use purple optical brightener in Greenlight Marine Grade Epoxy Resin

Epoxy and polyester resin can turn yellow or amber color for a few reasons, the most common being exposure to UV light. When UV light hits the resin, it breaks down the chemical bonds in the resin, which causes the resin to yellow. This process is called photodegradation.

Purple is a complementary color to yellow. This means that when purple is placed next to yellow, the two colors cancel each other out, making the yellow appear less yellow. This is why purple is often used in optical brighteners. The purple pigment in the brightener absorbs the yellow light that is reflected off of the surface, making the surface appear whiter.

In addition to making the resin appear whiter and brighter, the purple optical brightener in Greenlight Marine Grade Epoxy Resin also absorbs more UV light, which protects the resin and substrate from yellowing. 

Note: This resin looks really purple in the bottle and mixing bucket (in volume) but when applied in a thin coat (laminations and seal coats) it is clear with no visible purple hue - it looks bright white!

In addition, you can add epoxy tints and pigments to this resin with no change to the intended color. There is such a small amount of purple optical brightener it will not affect the pigment or tint color.

*Recommended sealcoat amount for surfboards is 3 oz. mixed resin per linear foot of board. For example, a 6'0" long surfboard would use 18 oz. mixed resin (6 x 3 oz.) for excellent results.

Also minimal brush strokes leads to a better finish. Brush it out once to cover and walk away.
