Tech Talk: How to prevent epoxy boards from turning yellow quickly?

01.05.2023

What’s up everyone! Welcome back to another Appletree Surfboards Tech Talk video. Today we’re gonna have a look at our new white line construction and how to prevent epoxy boards from turning yellow quickly.

White line boards

We’ve been doing the white line construction kiteboards for quite some time as sort of a slightly more budget friendly entry level surfboard in our range. It’s our normal models, but then in a slightly lighter construction and only available in this white colour. And you will see them quite a lot in the surf shops

The thing we’ve changed is that we got this new epoxy resin in our boards. And as you can see by this one, it’s much brighter than the old ones.

WHITE LINE BOARDS

Why do epoxy boards yellow?

The problem with epoxy boards is that epoxy, even when it’s new, it’s not completely clear. Epoxy always has got this slight yellow hue. So if you put it over a white blank, it’s never completely white. You can’t solve this.

Optical brightener

Nowadays we have an optical brightener in our boards. So it’s still the same epoxy, but it’s got a pigment in it that makes it look whiter than it actually is.

How to prevent epoxy boards from turning yellow

UV blocker

The new pigment makes the board really pop, as you can see by this one. Especially in the sun. It’s super bright. It’s super white. And then as an addition to that, we also have a UV blocker over the board, so it should stay white longer as well. 

Epoxy always has got this slight yellow hue. So if you put it over a white blank, it’s never completely white. You can’t solve this. But nowadays we have an optical brightener in our boards.

UV rays cause epoxy boards to turn yellow

Of course, like any white surfboard, it will yellow slowly over time. And this is due to UV rays. So the best way to prevent that from happening is to put your board in a bag when you’re done riding. Just keep it out of the sun, because it is the direct sunlight that is slowly yellowing the board. 

So to prevent epoxy boards from turning yellow quickly, keep it out of the sun. Don’t put it in your living room where the sun hits it.

Ultra white finish

This Applino V2 is the new addition to our lineup of our white line boards. From 2023 on all the white line boards will come in this new ultra white finish. Hope you like them! 

This was it for today, for this month. I’ll hope to see you next time in another Tech Talk video!
