Usage
DESCRIPTION
Umacoll 88M is a water- and processing aid - based polyurethane dispersion for 3D-laminating. Protect from Freezing!
FIELDS OF APPLICATION
Umacoll 88M 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 diaphragm and vacuum pressing.
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 up to +75 °C.

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 |
Stir thoroughly before use and filter to delete films and flocculated polymer to prevent spraying nozzle loading. Ready to use. |
|
Pot life |
Umacoll 88M pot life is not limited due to expire date. |
|
Tools |
Spray gun. Optimum nozzle diameter 1,2-1,8 mm, spraying pressure 2,4-4 bar. 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. Use dry tools for 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: 80-1200 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. |
Storage
STORAGE
Glue components should be kept in tightly closed original container in dry rooms, not below +5° up to +30°С. Protect from freezing!
PACKAGE SIZE
10 L, 30l (plastic bucket).
GUARANTED STORAGE LIFE
Umacoll 88M 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. Avoid skin or eye contact. Use rubber gloves to protect hands. Respiratory protection is required when spraying. Keep away of children. For detaled safety instructions, please read safety certificate.
RECYCLING
Packing materials are recycled as consumer waste.
