Polyurethane curing agent refers to the component containing isocyanate groups (NCO) in two-component polyurethane products, mainly used in combination with components containing active hydrogen, such as polyether polyols, polyester polyols, epoxy resins, hydroxy acrylic resins, etc. The addition of curing agent can not only improve the cross-linking degree and internal energy of the product, but also enhance the strength, weather resistance, and other properties of the final product.
Polyurethane curing agent has the following characteristics:
Easy to dry, wear-resistant, high hardness:
The cured coating has high hardness and wear resistance.
Good flexibility:
It has good flexibility and is suitable for various substrates.
Easy to polish:
The cured coating is easy to polish and polish.
Stable performance:
It can maintain good curing effect in both high temperature and room temperature environments.
Polyurethane curing agent is widely used in the following fields:
Adhesive:
Improve adhesive strength and weather resistance.
Coatings:
Enhance the hardness and wear resistance of coatings.
Ink:
Improve the drying speed and stability of ink.
Motorcycle parts, automotive surface coating, industrial coating, wood coating: used for the preparation of high-performance coatings.
In summary, polyurethane curing agent plays an important role in industrial production and daily life due to their excellent performance and wide range of applications.
