Non-toxic aminoplastic adhesive for medium density fibreboard and new application panel products of improved weather and biological resistance

Objectives

Recent concerns about the effect of formaldehyde on health are posing limitations to conventional formaldehyde-based adhesive systems that emit formaldehyde during use. Alternative adhesive systems containing isocyanates, phenolics, or tannins all have inherent problems of perceived health risks, or higher production cost.

Technical Approach

The main goal of this project is the development of a new generation of urea-formaldehyde (UF) adhesives with near-zero emission coupled with improved weather resistance. The incorporation to the adhesive of additives that will ensure biological resistance of the board will also be studied.

Expected Results

I. Direct Results

Amino resins producing boards with improved water resistance and lower formaldehyde emission.
Development of effective hardeners for the hardening of amino resins of very low formaldehyde content without depending on formaldehyde in order to improve their crosslinking and optimise board properties.
Amino resins producing boards with improved biological resistance by the fixation in a non-reversible manner of an easily diffusible non-toxic preservative, to the resin.

II. Indirect Results

Better understanding of how various reaction parameters affect the final properties of formaldehyde-based resins that will result in better control and increase in the reproducibility of such preparations.
Correlation of the microscopic structure with the macroscopic properties of the resins that could be useful for the development of adhesives for specialised applications.

Applications

The resins developed will be primarily marketed as low cost/high quality adhesives to be used in the production of wood-based panels. Alternative applications in other industrial sectors using amino resins (such as the cork and textiles industries) will also be examined.
