Hot Press Lamination of Veneers to various boards:
For the hot pressing of veneer to board, and for veneer splicing, National Edging supply both PVAc and UF glue manufactured by Jowat®
PVAc:
Jowacoll® 102.70: One component D3 (moisture resistant) for regions with high humidity. May be heat re-activated to prevent bleed - through of the adhesive to the surface of the veneer.
Jowacoll® 104.05: Long open time, medium to fast setting PVAc which produces a hard glue line.
Jowacoll® 102.20: D4 PVAc with the addition of 5% hardener
Jowat® 195 30. Excellent for wet environs.
Urea Formaldehyde: U.F.
Jowat® 950.20: Thermo setting U.F. resin in powder form with integrated hardeners and thickening agents. Simply add water to re constitute into a liquid urea formaldehyde glue with a pot life of 7 hours at an ambient temperature of 20°c. Meets the requirements of I.F. E1 pertaining to free formaldehyde emissions. Also highly suitable for producing fire doors.
Veneer Splicing:
Jowacoll® 128.70: Thermo re-activation glue for veneer splicing, especially on Fisher Ruckle veneer splicing machines. Veneers will not separate in hot press veneering.
When edging with genuin veneer the following Edgebanding Hotmelt advice should be considered.
-
Adhesive must have superior "wetting" properties.
-
Good penetration into the veneer grain and board edge.
-
A thin glue line giving a closer marriage of the veneer to the board edge.
Reduced glue line which equals reduced consumption, closer marriage of the veneer to the board edge all contributing in lower costs and superior bonding.
Higher heat resistance.
