YUG – COL ULTRA D3
PVAC adhesives have become one of the most important adhesives in wood -working industry several different approaches have been taken to improve the moisture and heat resistance of PVAC. Wood adhesives, to meet the European standards of non structural wood adhesives (BS.EN.204) or D3 standard. Now YUG COL-ULTRA conforms the D3 (BS.EN.204) standards of Europe.
It is aqueous polyvinyl acetate dispersion with cross linking properties and stabilization with polyvinyl alcohol.

It is qualified for water resistant and heat resistant wood glue. The dispersion exhibits an outstanding rapid increase in bond strength when pressed at temperature higher then 20Aºc. On hot press application, it shows accelerated increase of bond strength, making it most suitable for the short contact lamination of panels with laminate sheet finishing and for best forming finishes of panel edges and profiles. It also gives excellent bonding strength to wood joining. It’s bond exhibits an outstanding heat and water resistant.
- Water Resistant.
- Keeping joint in cold water (or room temp) for 6 to 12 hrs, take out and dry again, the joint strength will remain almost same.
- Keeping joint in hot water (temp up to 80Aºc) for 1 to 2 hrs, take out and dry again, the joint strength will remain almost same.
