[0:09]So we can make uh composites from large pieces of wood as we've seen, but we can also make composites from small pieces of wood. We can use chips or flakes or fibres. So chips could include sawdust of course. And if we're going to make effective composites using these wood particles, then we need an effective adhesive to be able to do that. And the sorts of adhesives that we use for this are urea formaldehyde which is used for indoor applications. Phenol formaldehyde, melamine urea formaldehyde, so that is UF, PF, MUF. And then there are other adhesives which are a bit more expensive like resorcinol based adhesives, resorcinol formaldehyde. And then we can get combinations, phenol urea formaldehyde, resorcinol urea formaldehyde, we can mix phenol with resorcinol. These adhesives here tend to be more water resistant. You'll probably find resorcinol adhesives, which are quite expensive, but they tend to be used more in the marine applications.
[4:28]Melamine urea as I say more for the decorative type of applications, the surfaces that we glue a paper impregnated paper onto the surface of a particle board to give you a decorative finish. Resorcinols tend to be rather more specialized as I say for high-value applications, particularly marine applications, that sort of thing.
