Product Description:
1,2,2,6,6-Pentamethyl-4-piperidinol is a hindered amine light stabilizer (HALS) intermediate used in the synthesis of more complex HALS compounds. It serves as a key building block for producing light stabilizers that protect polymers and other materials from degradation caused by exposure to ultraviolet (UV) light. These stabilizers are widely employed in plastics, coatings, and other applications where long-term UV resistance and durability are required.
Application:
Pentamethylpiperidol can be used as the main intermediate of hindered amine light stabilizer and synthesis of hindered amine light stabilizer, and can also be used as an important intermediate of medicine, bleach, epoxy resin crosslinking agent and other products.
