Desmodur RE is a highly active cross-linking agent, Used in the adhesives made by hydroxyl polyurethane, natural or synthetic rubber,
It has excellent bonding strength in rubber and cab be used in resin, antioxidant, plasticizing agent, pressure-sensitive etc.
It can be used as crosslinker instead of BAYER’s Desmodur RE
Two-component adhesive must be used within the applicaable period after putting in RE.
The length of applicable period is not only related to the polymer content of adhesive, but also other relevant components(like resin, antioxygen, plasticizer, solvent,etc.
When close to the applicable period,usually a few hours or one working day, adhesive becomes more difficult to operate, and viscosity rises soon.
Finally, It becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for around 20%), RE dose 4-7. Chloroprene rubber (Rubber account for around 20%), RE does 4-7.
Desmodur RE is primarily used as a hardener or crosslinker in various polyurethane formulations. Applications include:
1. Coatings: Desmodur RE is typically used in the formulation of high-performance coatings, including industrial and automotive coatings. It improves the durability, chemical resistance and weathering resistance of coatings.
2. Adhesive: Used in the production of polyurethane adhesives to improve bonding strength and resistance to environmental factors.
3. Sealants: Desmodur RE can be used in sealants to enhance flexibility, adhesion, and moisture and chemical resistance.
4. Foam: In some cases, it can be used to produce flexible or rigid polyurethane foam, helping to improve its mechanical properties and stability.
5. Elastomers: It is also used in the formulation of polyurethane elastomers, which require specific performance characteristics such as flexibility, elasticity, and abrasion resistance.
Please stored in the original sealed jar under 23℃, the products can be preserved stable for 12 months.
It very sensitive to the mosture; it will be produce carbon dioxide and insoluble urea in the reaction with water.
If exposure to teh air or light, it will speed up color changes, but the practical function will not be affected.
To properly store Desmodur RE, follow these guidelines:
1. Temperature: Store Desmodur RE in a cool, dry place. Recommended storage temperature is typically between 15°C and 25°C (59°F and 77°F). Avoid exposure to extreme temperatures.
2. Container: Store the product in the original container, tightly sealed to prevent moisture ingress and contamination. Make sure the container is made of compatible materials to avoid reactions.
3. Ventilation: Store in a well-ventilated area to minimize vapor accumulation. Avoid storage near fire or heat sources.
4. Humidity: Protect from moisture as isocyanates react with water, leading to the formation of carbon dioxide and creating a potentially hazardous situation.
5. Safety Precautions: Ensure storage areas are equipped with appropriate safety measures, such as spill containment measures and personal protective equipment (PPE) to handle leaks or spills in the event of a leak or spill.
6. Expiration Date: Check the manufacturer's recommendations for shelf life and expiration date. Use the product within the specified time frame for best results.

Yes, Desmodur RE, like other isocyanates, can be harmful to humans if not handled properly. Here are some key points about its potential health effects:
1. Inhalation: Exposure to isocyanate vapors can irritate the respiratory system and may cause airway sensitization leading to asthma-like symptoms in some individuals.
2. Skin Contact: Desmodur RE can cause skin irritation and sensitization. Prolonged or repeated contact may cause an allergic skin reaction.
3. Eye Contact: May cause serious eye irritation and damage. Wear protective eyewear when handling this material.
4. Ingestion: Ingestion of isocyanates may be harmful and should be avoided.
5. Safety Precautions: When working with Desmodur RE, appropriate personal protective equipment (PPE) must be used, including gloves, goggles and respiratory protection if necessary. Ensure that the workplace is well ventilated to minimize exposure.
When transporting Desmodur RE, specific precautions must be followed to ensure safety and regulatory compliance. Here are some key considerations to take into account:
1. Label: Ensure containers are properly labeled as per regulatory requirements. Labels include hazard symbols and handling instructions.
2. Packaging: Use appropriate packaging that is compatible with isocyanate. The container should be sealed to prevent leakage and exposure to moisture.
3. Temperature Control: Transport in a temperature-controlled environment and avoid exposure to extreme temperatures, which will affect the stability of the product.
4. Ventilation: Ensure that the transport vehicle is well ventilated to minimize the accumulation of vapors.
5. Personal Protective Equipment (PPE): Personnel involved in transportation should wear appropriate PPE, including gloves, goggles, and, if necessary, respiratory protection.
6. Emergency Procedures: Be familiar with emergency procedures in case of spills or leaks during transportation. Have spill control materials ready.
7. Avoid incompatible substances: Keep Desmodur RE away from incompatible substances such as water, alcohol, strong acids or bases as these may cause dangerous reactions.
8. Regulatory Compliance: Comply with all local, national and international regulations regarding the transportation of hazardous materials, including any special requirements for isocyanates.
