Catalyst DC2 is a delayed strong gelling catalyst with obvious maturation in the later stage, and can be used for polyurethane flexible molded foam and CASE materials;
The catalytic activity of the catalyst DC2 is stronger than that of the catalyst DC1.
Catalyst DC2 catalyst is a delayed catalyst for polyurethane foaming. It is used to promote urethane (polyol) in soft molded polyurethane foam and CASE applications. -Isocyanate) reaction provides a delayed catalyzed reaction while maintaining a strong back-end curing effect. Compared with the catalyst DC1 catalyst, the catalyst DC2 catalyst has stronger catalytic activity.
Typical physical properties:
|Appearance||Light yellow transparent liquid|
|Flash point, ℃||66|
Strong gel polyurethane catalyst
Delayed catalytic polyurethane foaming time
Suitable for various TDI, T/M, MT and MDI systems and CPU elastomers, CASE fields
Recommendations for use:
Catalyst DC2 catalyst can be used alone, or as a co-catalyst together with other polyurethane catalysts, so that the formula can adjust the specific system reactivity. When used as a co-catalyst, the catalyst DC2 catalyst can enhance the curing of the system without significantly changing the front-end reaction of the reaction.
Keep it unopened for two years
Storage and transportation:
Should be sealed and stored in a dry, cool and ventilated warehouse
200KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Store in a cool, dry place, keep the container tightly closed, and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry and cool place with proper ventilation. All storage containers must be well sealed to avoid contact with water or other influential substances, as this may change the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are inappropriate and should be avoided as much as possible.
