Fibreglass is a mat of glass fibres used in surfboard or boat construction. The mats come in several thicknesses. When combined with a thick liquid called resin the fibreglass / resin combination produces a hard surfaced coating that is light weight but strong.
There are a variety of surfboard constructions coming out now including epoxy, firewire, Solomon and many others but the traditional surfboard is a polyurethane blank and fiberglass. The polyurethane blank aka foam is shaped down to a specific shape then coated with a resin that is strengthened by fiberglass cloth.
Hobie Alter made some of the first foam surfboards, and he used polyurethane foam. But basically, any rigid plastic foam that won't melt when you put resin on it will work.
No, resin is not a varnish .
The resin commonly used for uranium extraction is called anion exchange resin. This resin is designed to selectively bind and separate uranium ions from solution by exchanging them for other ions present in the resin. This process is used in the recovery of uranium from ores, mining solutions, or nuclear waste.
Epoxy resin can be used as a jointing compound.
As a varnish
Ion exchange resin is used in separation, purifying and decontamination processes. The resin is an insoluble matrix. They are usually made of cross-linked polystyrene molecules.
The mass doesn't depend on the units used to describe it.In metric units, the mass is(the surfboard's weight in newtons)/(9.8)kilograms. That's the same as(0.4536) times (the surfboard's weight in pounds) kilograms.
Resin is a sticky flammable substance that is not water soluble. The Ancient Egyptian used resin to help preserve the body of the dead.
