Thermosetting resins are defined as resins that change irreversibly under the influence of heat.
Amino resins are thermosetting resins formed in two-step chemical processes between amines and their derivatives and formaldehyde.
Orica Adhesives and Resins manufactured close to 200,000 metric tonnes of MF, UF and MUF resins in 2004 making them the largest producer in Australia.
These resins are used as the binder in reconstituted wood products, such as particleboard and fibreboard.
One aim of collaborative research with Orica Adhesives and Resins is to design and synthesise novel amino monomers.
The incorporation of derivatized monomers can enhance resin characteristics such as solubility, flexibility and strength.
By labelling amino monomers with isotope labels, it is possible to correlate the molecular structure of the resin to its physical properties using NMR spectroscopy.
Furthermore, it is now feasible to investigate the extent of co-polymerisation in resins so that the chemical structure of the resin can be fine-tuned.

Resins can be tagged by fluorescent molecules. In this case visual techniques
can be used to correlate resin distribution to the physical properties
of wood based composite panels. New multi-functional amino monomers have
therefore been synthesised in order to improve resin distribution and properties.
