application  
   Dispercoll U54 shows outstanding bonding properties to many synthetic materials and natural materials. Adding 2-5% (weight ratio) of water-emulsifiable polyisocyanate curing agent-Desmodo D can improve the heat of bonding. Stability, plasticizer resistance, grease and oil resistance. The curing agent should be added before the adhesive is used and should be dispersed evenly. Pay attention to the potable time of the mixed adhesive. In order to expand the technical performance of special application fields or customized products, resin dispersions, emulsifiers, thickeners, etc. can also be added. Before use, especially before spraying, the formulated adhesive product must be filtered to remove polymer particles that may form in the adhesive.

  Package  
120kg polyethylene plastic drum, 1100L container, tank car.

store
Stored in the original airtight container at 23°C, the shelf life of Dispercoll U54 after shipment is 6 months. Storage should be avoided at temperatures above 30°C. The storage temperature should not be lower than 5℃, otherwise the product will freeze and solidify. A frozen Wikipedia U54 will be completely ineffective. The packaging container must be tightly closed and protected from direct sunlight, otherwise the evaporation of water will cause it to form a non-redispersible polymer film.
