Usage
DESCRIPTION
One component water poly urethane-dispersed glue with processing aids for 3-D lamination. Improved thermo stability at high temperature activation. Protect from freezing!
FIELDS OF APPLICATION
Umacoll 81M is used for wood-based textured boards (HDF, chipboards, laminated chipboards, MDF, etc) 3D-lamination and thermo veneer with thermoplastic films (PVC, PET, ABS) in membrane and vacuum presses.
SUBSTRATE
Easy to spray. Suitable viscosity application. Finished adhesive bond has a high initial strength, moisture and steam resistance, frost resistance up to-40°C and thermal resistance not less than +80°C.Technical information

Application
INSTRUCTION FOR USE
Gluing materials surface should be dust-free, without fat and other contaminants.
CONDITIONS
Working temperature +15 °С, optimum temperature (20±2)о С and air humidity no more than 65%. Gluing materials and glue should be withstood to the room temperature before use.
WORKING CONDITIONS
|
Preparing |
Ready to use. Stir thoroughly before use and filter through the polymer mesh to delete films and flocculated polymer to prevent spraying nozzle loading. |
|
Pot life |
Umacoll 81M viability is not limited during the warranty period of storage. |
|
Tools |
Spray gun. Optimum nozzle diameter 1,2-2,0 mm, spraying pressure 2,4-4 bar. (Nozzle diameter and pressure data are obtained using DeviBiss PRI PRO 210-14k. Pressure is set at injection tube output). Nozzle diameter and optimum pressure should be defined in each case individually. Glue contact materials should be corrosive resistant. No contact with copper, aluminium and zinc (glue coagulation is possible). |
|
Cleaning |
Equipment is washed with water before glue drying. Dry glue is cleaned mechanically. Tools has to be dry before refilling. |
|
Application |
Spray gun on glued materials bearing side. Glue consumption is about 50 g/m2. Milled rounded 3D - surface areas (surfaces with high absorbency) should be retreated with glue second layer after first layer complete drying. Optimum technological parameters should be set regarding manufacturing conditions and materials used. |
|
Adhesive |
Bonding layer must be dried at room temperature before pressing. First layer drying is 30 min., second layer drying is 60 min. To fasten drying time use heat increasing drying temperature up to 30-350 C. Bonding is achieved by adhesive line thermo activation. Pressing conditions: - Pressing time: 30-90 s - Press temperature: 90-1300 C* - Pressing pressure: 4-5 bar Optimum technological parameters should be set regarding manufacturing conditions and materials used. Glued parts can be machined after 6 hours. Full time of hardening is 3-7 days. *Depends on the film and other pressing conditions. |
Storage
STORAGE
Should be kept in tightly closed original container in dry rooms, not below +5°С up to +30°С. Protect from freezing!
PACKAGE SIZE
30 L (plastic bucket).
GUARANTED STORAGE LIFE
Expire date is 6 months in case if delivery and storing rules are followed. After expire date shouldn’t be used without tests.
HEALTH AND SAFETY
Careful air change is necessary. Use rubber gloves to protect hands. Avoid skin or eye contact. In case of contact with eyes or skin wash with water and consult a doctor. Keep away of children. During spraying required respiratory protection. For detaled safety instructions, please read safety certificate.
