PLYWOOD ADHESIVES RESINS

Description

Urea, phenol and melamine formaldehyde adhesives for the manufacture of plywood.

Plywood adhesives are synthetic glues made from chemical raw materials through condensation polymerizatiton. The glues used are thermosetting types which cure or harden by the action of heat or a catalyst.

Urea-formaldehyde (UF) and phenol-formaldehyde (PF) resins are two common types of plywood adhesives.

UF resins are used for the manufacture of interior grade plywood while PF resins are for exterior and marine-grade plywood. A catalyst or hardener is added to the UF resins to accelerate curing or hardening. PF resins, on the other hand, can be made to cure and harden under heat with or without a catalyst.

TYPES
APPLICATIONS
Urea-Formaldehyde
  • Interior grade hardwood plywood. High tack for pre-press. Passed U.S. standards.
  • Interior grade particle and medium density fiberboard
Urea-Melamine
  • Formaldehyde Interior grade particle and medium density fiberboard with good water resistance and very low formaldehyde emission
Phenol-Formaldehyde
  • Exterior and marine grade plywood. Meets U.S. and British standards.
Hot Press Catalyst 
  • Catalyst for UF  for hot-press operations. Fast cure.
Splicer Catalyst
  • Catalyst for UF for splicing veneers.
Cold Press Catalyst
  • Catalyst for UF for cold-set operations. Fast cure
Hot Press Catalyst
  • Fast Catalyst for UF.
