Urea-formaldehyde, phenolic and melamine-formaldehyde resins for wood industrial adhesives
This standard specifies the classification, technical requirements, test methods, inspection rules and marks, packaging, transportation and storage of urea-formaldehyde, phenolic and melamine-formaldehyde resins for wood industrial adhesives and paper impregnation.
This standard is not applicable to emulsion phenolic resin.
Adhesive: Under certain conditions, by adhering to the material, can be bound together by the adhesives.
Urea-formaldehyde resin: A resin prepared by condensation of urea (urea) and formaldehyde. It belongs to amino resin.
Phenolic resins: resins that are worth polycondensation of phenols and aldehydes. Phenol formaldehyde resin is commonly used.
Melamine formaldehyde resin: A resin prepared by condensation of melamine and formaldehyde.
