Use of paraformaldehyde in resin production offers many advantages as compared to aqueous formaldehyde:

1. Higher productivity from existing equipment and less water to be removed from the resin product.
2. It takes the form of prilled, is stable and very easy to store. Paraformaldehyde storage is less expensive than the storage of formaldehyde solution, which requires expensive tanks and which may need stabilization or be kept warm.
3. Use of paraformaldehyde is convenient and safe. It avoids pollution arising from the disposal of the distillate obtained in the thermosetting resin production which is contaminated with organic matter.
4. Paraformaldehyde does not need to be dissolved in water in order to take part in a chemical reaction.
5. It eliminates the risk of transporting liquid formalin, which is notoriously dangerous. Perfect for small uses straight from the bag.
