How do you increase self life of liquid Phenol-Formaldehyde Resin?

∙ 14y ago
Liquid resols of phenol formaldehyde resin can be stored for longer time. Free formaldehyde needs to be controlled at the end of the reaction. This will be possible by adding formaldehyde scavanegers. The pH of reaction is most important in this regard. Adjust the pH of the PF resin to 7 to 7.5 using acid such as acetic acid to increase in shelf lift. Some resols can be stored up to 6 months below 25 deg C.

Repairing Resin Wicker Patio Furniture?
Resin wicker patio furniture is a durable and inexpensive alternative to other types of outdoor furniture. The resin material can be easily cleaned with household products and can be washed with a garden hose. In cases where there is a stain that will not come out or some damage, the resin coating can be gently sanded down with sand paper until a clear area is revealed. This cleaned section can then be coated in wax to restore the finish and extend the life of the patio furniture.
