Covestro Desmodur RN Shoe Adhesive Crosslinker Hybrid Polyisocyanate Excellent yellowing resistance

Nature
Desmodur® (Desmodur®) RN is used as a cross-linking agent for Desmocoll® (Desmocoll ®), natural or synthetic rubber-based adhesives, especially suitable for light-colored adhesives for bonding rubber materials. Cooperating with appropriate adhesives can ensure minimal discoloration under light conditions.

Apply
Add After Desmodo® RN, the two-component adhesive must be used within the pot life. The pot life is not only related to the polymer content in the adhesive, but also to other components (such as resins, antioxidants, plasticizers, solvents, etc.). When the pot life is approaching, usually a few hours or a working day, the adhesive becomes It is more difficult to apply, and the viscosity will increase rapidly. Eventually, an irreversible gel occurs.

Amount of crosslinking agent needed for adhesive You can refer to the following data:
100 Parts by mass adhesive       Desmodo® RN dosage de Smoco® (Hydroxy Polyurethane)
( Polyurethane content about 20%) 4-7
Bayer Flat® (Neoprene)
(rubber content about 20%) 4-7

Packaging
metal Bottled: 0.75 kg 1L bottle

Save
in Stored in airtight original packaging at 23°C, the product has a shelf life of 6 months.
all Desmodeo® products are sensitive to moisture conditions, and react with water to produce carbon dioxide and insoluble urea, so the container must be tightly closed. The introduction of water in any form (wet containers, aqueous solvents, humid air) should be avoided, otherwise the carbon dioxide produced may lead to a dangerous increase in pressure in the container.
Exposure Yellowing will be accelerated under air or light, but it has no effect on the basic performance of the product.

Disposal
useless The product residues should be incinerated according to local regulations and should refer to the European Waste Catalog (EWC) for industrial waste code details. See Material Safety Data Sheet for details.
No In areas subject to German packaging regulations, carefully cleaned containers or packaging can be incinerated in local or industrial incinerators. For containers that have not been cleaned of pollutants, the hazard signs should be retained.
