HDDA, also known as 1,6-hexanediol diacrylate, plays a vital role in the formulation of light-curable coatings, inks and adhesives as a bifunctional reactive diluent. Its unique molecular design, low viscosity and superior solubility allow it to significantly reduce viscosity in the system while maintaining strong adhesion. For this reason, HDDA is a commonly used bifunctional monomer in UV curing technology and is highly regarded for its fast curing speed and low volatility.
The characteristics of HDDA mainly include the following points:
1. Excellent dilution performance: The low viscosity of HDDA makes it an ideal diluent, which can significantly reduce the viscosity of the system and improve the fluidity of the paint, thus facilitating the construction and curing process.
2. Excellent adhesion: The molecular structure of HDDA enables it to form a strong bond between the coating and the substrate, ensuring the coating has excellent adhesion and durability.
3. Excellent solubility: HDDA can be well dissolved in a variety of resins and additives, which makes it compatible with various systems and improves the stability and reliability of the overall formula.
4. Efficient curing speed: HDDA has a very fast reaction speed, which means it can be cured quickly, thereby shortening the production cycle and improving production efficiency.
5. Low volatility and environmental protection: HDDA has low volatility and slight odor, which makes it safer to use while reducing negative impact on the environment.
6. Excellent weather resistance: HDDA has excellent chemical resistance, water resistance and heat resistance, which allows it to maintain stable performance in various harsh environments and extend the service life of the coating.
