Phenol-Resorcinol-Formaldehyde (PRF) adhesives
PRF adhesives are classified as thermosetting polymers and are produced by
a condensation polymerisation between formaldehyde, phenol and resorcinol.
PRF adhesives are cold-setting with very high weather and water resistance
as well as heat resistance to be used in products for exterior, humid and interior
climates. PRF adhesives can also be used in hot bonding and radio frequency
curing equipment to speed up the curing process.
Dynea manufacture a broad range of PRF adhesives in Europe, North America
and New Zealand together with different types of powder, slurry and liquid
hardeners.
PRF adhesives are mainly used in the production of load-bearing timber structures;
hence, Dynea’s PRF adhesives are tested and approved by official testing
bodies for use in the building industry. They can also be used for gluing of
alkaline boards.
A wide range of resin technologies have been developed by Dynea, including many hardeners to offer the best possible solution for a variety of customers and end uses. Our broad range of PRF adhesives can thus meet specific plant performance criteria for pot life, assembly time, curing speed, press and curing equipment and formaldehyde emission requirements.
Dynea’s PRF adhesives are capable of meeting or exceeding the various performance criteria required by the different standards EN, ASTM and JAS.
