Verwendung und Herstellung
Uses
Amino resins are thermosetting plastics formed from the reaction of formaldehyde and an amino group, usually urea or melamine. They are used as bonding agents in plywood and particle board and wrinkle-resistance agents in textiles. They are also molded for electrical devices and various commercial and home applications. [LaDou (2nd ed.), p. 522-3] Urea-formaldehyde resins are used in hot-box and no-bake systems for coremaking in foundries. [Burgess, p. 123-126] Used in leather tanning; [PMID 21938525]
Urea-formaldehyde foam was banned in home insulation in 1982 because the release of formaldehyde was an indoor air hazard. [LaDou (2nd ed.), p. 522]
