Purpose |
Colorless to pale yellow liquid. Color does not affect bonding performance |
Nature
As a crosslinking agent, Desmodur® RC is suitable for adhesives formulated with Desmocoll®, natural or synthetic rubber, especially for light-colored adhesives for bonding rubber materials.

Nature/Application
Add After Desmodeo® RC, 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 More difficult to apply, viscosity builds up quickly. Eventually, an irreversible gel occurs.
The amount of crosslinking agent required for the adhesive can refer to the following data:
100 parts by mass of adhesive Desmodo® RC dosage
Desmoco® (Hydroxy Polyurethane)
(Polyurethane content about 20%) 4-7
Bayerpin® (Neoprene)
(rubber content about 20%) 4-7
Packaging
metal Container: 0.80 kg 1L bottle
Save
in Store at 23°C in tightly closed original packaging.
All Desmodos® products are sensitive to wet conditions, Reacts with water to produce carbon dioxide and insoluble urea, so containers must be kept 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 to air or light will accelerate yellowing, but it has no effect on the basic performance of the product.
Safety: Dangerous Nature
height Flammable. Harmful if inhaled. Irritating to eyes. Inhalation may cause sensitization. Repeated exposure may cause skin to dry out or crack.
Safety Data Sheet (072323), including product identification, transportation, storage, and product-related operations, safety and ecology, etc. For information, please refer to
Disposal
Unused product residues should be incinerated according to local regulations, which should refer to European Waste Catalog (EWC) Industrial Waste Coding Breakdown. See Material Safety Data Sheet for details.
In regions not subject to German packaging regulations, carefully cleaned containers or packaging can be disposed of in local or industrial incinerators incineration. For containers that have not been cleaned of pollutants, the hazard signs should be retained.
