UMACOLL 87M
Technical conditions: 2252-034-20514586-15
- Container:
- 30 kg (plastic bucket)
Description
One component water-based polyurethane-dispersed adhesive with technological additives for 3-D lamination. The adhesive has an increased thermal resistance with a sufficiently long reactivation time.
The product should be protected from freezing!
Usage
Umacoll 87M is designed for 3D-gluing and heat-setting of relief panels of wood materials (fiberboard, chipboard, chipboard, MDF and others) with thermoplastic furniture films (PVC, PET and ABS) in membrane and vacuum presses.
Specificity of application
The adhesive has a good spraying ability, provided with a viscosity-friendly coating. The resulting adhesive seam in the finished product has a high initial strength, resistance to moisture and steam, frost resistance up to -40°C and heat resistance not less than +110°C.

Application
The surface of the materials to be bonded must be dust-free, should not have obvious fat and other impurities.
Application conditions
Operating temperature - from + 15ºС, optimum temperature (20 ± 2)ºС, humidity of air - no more than 65%. Adhesives and materials must be acclimatized to room temperature before recycling.
Application process
|
Preparation |
Before use, the adhesive should be thoroughly mixed and strained through a polymer mesh to remove the film and the coagulated polymer to prevent the nozzle from clogging during spraying. Umacoll 87M is fully ready for use. |
| Viability | The viability of Umacoll 87M is not limited during the warranty period of storage. |
| Instruments | Spray gun. The optimum diameter of the nozzle is 1.2-2.0 mm, the spray pressure is 2.4-4 bar. (Data on the diameter of the nozzle and pressure are obtained using DeviBiss PRI PRO 210-14k .The pressure is set at the outlet of the discharge pipe). In each particular case, the optimum pressure and nozzle diameter must be selected individually. Materials contacting with the adhesive must be corrosion-resistant. Avoid contact with copper, aluminum, zinc (may lead to coagulation of the adhesive). |
| Washing | Equipment and tools after use, rinse with water, avoiding the drying of the glue. In case of glue drying, the tool should be cleaned of the hardened adhesive residues mechanically. Before refilling, tools must be dry. |
| Application |
It is made by a spray gun on the bearing side of the glued materials. The consumption of glue is about 50 g/m2 in plasti. On the milled rounded 3D-surface areas (surfaces with high absorbency) should be applied a second layer of glue after drying the first layer. The optimal technological parameters should be established with respect to the conditions of a particular production and the materials used. |
| Gluing |
Before pressing the adhesive layer must be dried at room temperature. Drying time of one layer-30 minutes, 2 layer-60 minutes. The drying process can be accelerated by supplying heat, increasing the drying temperature to 30-35ºС Bonding is carried out by thermal activation of the adhesive seam.
Pressing parameters: The optimal technological parameters should be established with respect to the conditions of a particular production and the materials used. Before further processing of the parts must be maintained for at least 6 hours. Full curing of the glue joint takes 3-7 days. |
Storage
Store in tightly closed containers of the manufacturer in dry rooms at temperatures from +5 to +30°C. Do not freeze!
Warranty period of storag
The warranty shelf life of Umacoll 87M is 6 months from the date of manufacture, provided that the consumer observes the rules of transportation and storage. After the expiration of the storage warranty period, it is not recommended to use the product without laboratory testing.
Precautionary measures
During the work, it is necessary to thoroughly ventilate the room. Avoid contact with skin and eyes. Use rubber gloves to protect hands. After contact with skin, wash with plenty of water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep out of the reach of children. During spraying required respiratory protection. For complete information, see the safety data sheet for the product.
Recycling
Tare from the glue to be disposed of as household waste.
