Covestro Dispercoll® U53 anionic polyurethane dispersion

Features
Dispercoll® (Dispercoll®) U53 is a high molecular weight water-based anionic polyurethane dispersion, a raw material for heat-activated polyurethane adhesives, and can be used in furniture, automobiles, shoemaking, construction and other industries. Due to the structural characteristics of the polymer, DABE® U53 exhibits excellent bonding properties to a variety of materials, including soft PVC.        

Basic product performance

*The above data only give general information, not the characteristic properties of this product.

Application
Dibaike® U53 exhibits excellent bonding properties to many synthetic materials and natural materials, adding 2-5% (weight ratio) of water-emulsifiable polyisocyanate curing agent - Desmodos®, which can improve the thermal stability of bonding, plasticizer resistance, grease resistance and oil resistance. The curing agent should be added before the adhesive is used, and should be dispersed evenly. Pay attention to the working 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.

Packaging
      120kg polyethylene plastic drum, 1100L container, tanker.

Save
  Stored in the original airtight container at 23°C, the shelf life of Dibaker® U53 is 6 months. Storage temperatures above 30°C should be avoided. The storage temperature should not be lower than 5°C, otherwise the product will freeze and solidify. Freezed Dibak® U53 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.

Waste Disposal
  Unused Residue® product residues should be incinerated according to local regulations. Polymer dispersions should be disposed of under special supervision and should not pollute soil or surface water.

Safety: Hazardous nature
  According to EU standards, the product poses no hazard to health and the environment. Please refer to the safety information (077368) for product identification, transportation, storage, product handling, safety and ecological impact.
