Claims (12)

1. Klæbemiddelsystem, der omfatter a. en harpikskomponent, der omfatter en urinstofbaseret aminoharpiks, som har et F/NH2-forhold på fra 0,3 til 0,65, hvilket F/NH2-forhold er defineret som det molære forhold mellem formaldehyd og summen af alle nitrogenatomer undtagen dem i ringstrukturen af aromatiske grupper; b. en hærdende komponent, der omfatter mindst en syre, et syredannende salt eller et surt salt; og, c. en vandig dispersion af mindst en polymer, der omfatter mindst en af enten polyvinylacetat (PVAc) eller polyethylenvinylacetat (EVA); hvilket klæbemiddelsystem omfatter intet eller mindre end 0,9 vægt-% urinstof, baseret på vægten af hele klæbemiddelsystemet, ud over et eventuelt tilstedeværende urinstof i den urinstofbaserede aminoharpiks.
2. Klæbemiddelsystem ifølge krav 1, hvor urinstof-formaldehyd-harpiksen har et F/NH2-forhold på fra 0,4 til 0,6.
3. Klæbemiddelsystem ifølge krav 2, hvor urinstof-formaldehyd-harpiksen har et F/NH2-forhold på fra 0,45 til 0,55.
4. Klæbemiddelsystem ifølge ethvert af kravene 1-3, hvilket klæbemiddelsystem, ud over et eventuelt tilstedeværende urinstof i den urinstofbaseret aminoharpiks, omfatter intet eller mindre end 0,5 vægt-% urinstof, beregnet på den totale vægt af hele klæbemiddelsystemet.
5. Klæbemiddelsystem ifølge krav 4, hvilket klæbemiddelsystem, ud over et eventuelt tilstedeværende urinstof i den urinstofbaseret aminoharpiks, intet urinstof omfatter.
6. Klæbemiddelsystem ifølge ethvert af kravene 1-5, hvor den mindst ene polymer omfatter polyethylenvinylacetat (EVA).
7. Klæbemiddelsystem ifølge ethvert af kravene 1-6, hvor den hærdende komponent omfatter mindst et aluminiumsalt.
8. Klæbemiddelsystem ifølge ethvert af kravene 1-7, hvor mængden af syre, syredannende salt og surt salt i klæbemiddelsystemet er på fra 0,1 til 25 vægt-% af mængden aftør urinstofbaseret aminoharpiks.
9. Klæbemiddelsystem ifølge ethvert af kravene 1-8, hvor vægtforholdet mellem tør urinstofbaseret aminoharpiks og tør polymer i klæbemiddelsystemet er på fra 45:1 til 1:15.
10. Fremgangsmåde til fremstilling af et træbaseret produkt, hvilken fremgangsmåde omfatter påføring af et klæbemiddelsystem ifølge ethvert af kravene 1 -9 på mindst én overflade af et eller flere stykker af et træmateriale, der forbinder et eller flere stykker med et eller flere yderligere stykker af et materiale og trykke stykkerne sammen.
11. Træbaseret produkt, der kan opnås ved fremgangsmåden ifølge krav 10.
12. Anvendelse af et klæbemiddelsystem ifølge ethvert af kravene 1-9 til sammenføjning af et eller flere stykker af et træmateriale med et eller flere yderligere stykker af et materiale.
