AJ339 Water-Based Polyurethane Vacuum Pressing Adhesive
This adhesive, with the ability to resist moisture and high temperatures, is an excellent choice for coating cabinets, bathroom wooden doors, sanitary ware, and interior decoration. It’s very good spray pattern ensures optimal use and uniform coverage. Additionally, the high tensile strength of AJ339 helps ensure ideal adhesion, even in conditions where surfaces are exposed to harsh environments.
Product Advantages
Why choose AJ339?
Resistance to Moisture and High Temperatures: Suitable for coating parts exposed to moisture and high temperatures.
Very Good Spray Pattern and Uniform Coverage: Provides exceptional surface quality for various types of wood.
High Tensile Strength and Ideal Adhesion: The adhesive has high tensile strength and strong adhesion.
Application Method
The application method for the vacuum pressing adhesive is as follows:
- Before using the adhesive, ensure proper storage conditions and shake the container well.
- AJ339 is a water-based polyurethane product and should not be mixed with water or other chemicals.
- The vacuum machine must be technically sound. All its elements should be turned on, and it should reach a vacuum pressure of 0.7 bar at the appropriate time.
- MDF parts should be well and evenly sanded. The adhesive should be sprayed on the MDF surface in a dust-free environment at a temperature between 18 to 30°C and humidity of 55 to 60%.
- Spray the adhesive on the MDF surface with a spray gun from a distance of 10 to 15 cm. Edges and machined parts should be sprayed twice (with a very short interval between sprays).
- The nozzle diameter of the spray gun should be 1.8 to 2 mm. The standard air pressure for spraying is 3 to 4 bar.
- The adhesive consumption is about 50 to 70 gr/m² for flat surfaces and 80 to 110 grams for three-dimensional surfaces.
- The activation temperature of the adhesive is between 60 to 65°C.
- Place the glued part in the machine under appropriate temperature and pressure. Remove the coated MDF part from the vacuum membrane machine 2 to 3 minutes after turning off the heating system and suction.
- Allow the glued part to acclimate to room temperature for about 2 to 3 hours, then adjust the PVC angles.
Tips for Best Results
- Storage: Store the adhesive in a cool, dry place away from direct sunlight. The recommended storage temperature is between 10-30°C. Ensure the container lid is tightly closed.
- Cleaning: Tools and equipment used for applying the adhesive can be easily cleaned with water after use.
By following these tips, you can achieve optimal performance and durability with AJ339 Water-Based Polyurethane Adhesive for MDF parts!
