Description
Successful pressing depends as much on the right glue as it does on the right press. To assure the best bond possible we have developed Unibond 800, a two part liquid urea resin glue for use with the VacuPress. Urea resin is the industry standard for veneering glues, but most require high temperature for proper bonding. Unibond 800 has been formulated to provide the same bond quality at room temperature, making it an excellent choice for vacuum pressing.
Unibond 800 is a modified urea resin formaldehyde two part adhesive with a translucent liquid resin and a powdered hardener. Unibond 800 is designed to provide a rigid, gap filling glue line with faster than usual set times.
Applications
- Veneering flat and curved parts.
- Bonding plastic laminates.
- Laminating curved panels and bent laminations.
- Assembly glue for furniture, cabinets, and general joinery.
Distinctive Properties
- Rigid glue line – Eliminates crazing and cold creep.
- Low pressure bonding – Excellent gap-filling abilities up to 0.02.
- Highly water resistant – Good for moisture sensitive areas.
- Neutral tan color – Suitable for lighter and medium tone woods. Availible in dark for deep tone woods. White and dark brown tints are availible for extremely blond woods as well as extra dark ones – One 8 oz. bottle of tint will color a full 5 gallon pail at full strength.
- Adjustable set time – Set times can be altered by temperature and mixing ratios.
- Excellent open assembly time – Perfect for large panels and multi-layered laminations where clamping pressure may be delayed.
- Mixes easily – Does not lump – and cleans up with soap and water.
- Low shrinkage – For maximum panel stability.
