Frequently Asked Questions

What are blue light absorbers used for?

Blue light absorbers like Lotsorb B-100 and B-60 are used to block high-energy visible (HEV) light in the 370–480 nm range. They protect materials from degradation and reduce eye strain in optical films and display coatings.

Can photoinitiators work under visible light?

Yes, products like Lotcure 784 are specifically designed to initiate polymerization under visible light, making them ideal for applications where UV exposure must be minimized.

Are your UV absorbers safe for food packaging?

Many of our UV absorbers are compliant with international regulations for indirect food contact. Please consult the TDS/SDS for specific compliance details.

Do you offer custom synthesis?
