can be added directly to the uf resin mix or a component of a uf resin mix thereby eliminating the need for a separate application spray acetoacetamide does not interfere with the curing process of the resin nor does it affect moisture absorbency of the finished product as does urea although today it is more costly than urea it may be used at application levels far less than urea and still be effective in achieving very substantial reduction in formaldehyde release from composition board products as it has been discovered also to increase bond strength of particle board its use enables a lesser amount of the resin to be required without degradation in bond strength this can effect a cost savings that can generally offset the cost of the scavenger for which it is in effect substituted acetoacetamide also has been discovered to demonstrate a superiority as a formaldehyde scavenger over other known scavengers when used in the process of manufacturing durable press finished fabrics it is believed to be truly the only known commercially viable formaldehyde scavenger that can reduce the formaldehyde level of durable press finished fabrics to 25 ppm or lower as measured by aatcc test method 112 1984 without affecting fabric properties and at economic usage levels 10 000 pounds of particle board at 25 lbs cu ft was produced by spray treating wood particles with the following identified urea.
