Whether you are looking at shaping a surfboard or are preparing to repair damage on your surfboard, you are in the right place. This article discusses the best surfboard resins to use and other things about resins you need to know. Resins are used to bond the cloth to the foam blank during the process of surfboard shaping. They are poured straight onto the fabric and the board until the material is entirely soaked and saturated.
Resins come in two types, polyester resin, and epoxy resin. Both of them may be used with PU polyurethane foam. But, only epoxy resin may be used with polystyrene foam. These two materials are used with PU foam blanks. On the other hand, it is more susceptible to cracks and dings.
The problem is how they break down and dissolve once the polyester resin is applied. In this case, only epoxy resin can be used. Epoxy resins are lighter, making them buoyant, and are typically stronger. Compared to polyester resin, epoxy has a higher resistance to cracks and dings. Along with the excellent resistance to damages is the more expensive price tag. Deciding on which resin to pick is critical. After all, it is what holds the surfboard together. To help you narrow down your choices, here are 5 of the best surfboard resins in the market today.
It is a convenient mix when you are new to shaping or repairing your surfboard. You will like how easy it is to put together, cure well, and sand well, too. Sometimes, blushing and peeling happen. You can prevent that by getting Additive F from the same brand. Add it to eliminate flushing and flaking. At the same time, the combination makes saturating your fiberglass easier.
It is UV stable and has been optically brightened to make the surfboard appear clearer and whiter. We performed controlled 4-point benchtop tests to answer that question. This fact dispels a common myth that epoxy boards are stiffer than polyester boards.
That myth most likely came about because so many epoxy resin boards are built around soft EPS cores. Those cores require more glass, carbon fiber and often high-density sandwiched foam sheets to be strong enough to surf. All of that added reinforcement makes the boards stiff. So what flex is best? Epoxy or Polyester? It's really a matter of personal preference and depends on your riding style. However, you might not be charging powerful North Shore waves and instead looking to get the most zing out of your turns in average conditions.
Chatter- A lot of people worry that their board will chatter if they get it glassed with epoxy. Also, the foam can melt from this, too. So which is better? They each have their own inherent pros and cons, and beyond that, even more important is your own personal preference. Many people have the idea that poly is better because almost no pro surfers on tour ride epoxy boards.
This is simply absurd! The other We typically need different equipment. On the other side, other people have the idea that epoxy is the only way to go because poly is so much weaker. Again, not really true. Poly resin has a bit more give to it without being brittle, which can be a good thing for surfboards, as well. So neither one is better than the other, they just have different properties; pros and cons. They both certainly have their own place.
So what place do they have?
