Simply described, photoinitiators are chemicals that generate radicals upon exposure to light. A more complete description would include all the complexities inherent with the chemical nature of photoinitiators including type, concentration and absorptivity. All of these factors must be taken into consideration when optimizing a light-curable formulation.
With PL Industries, the new division of Esstech Inc., we can now provide the monomers, adhesion promoters, oligomers, photoinitiators and technical expertise to guide you in your material selection. The following is an example of our photoinitiator products.
|
PL-CQ |
Description: Type II, fine yellow powder, very common and effective for dental restoratives, heat aids in dissolution |
|
PL-TPO |
Description: Type I, off-white, crystalline powder, dissolves in most monomers, exhibits photo-bleaching properties |
|
PL-PPD |
Description: Type II, yellow liquid, believed to have a lower rate of polymerization that is not detrimental to overall conversion |
|
PL-EDB |
Description: a tertiary amine synergist typically used in combination with type II photoinitiators such as PL-CQ |
|
X-866-0000 |
Description: solid, off-white amine co-initiator that is low in color, requires melting or crushing to simplify incorporation |
|
X-867-0000 |
Description: a clear, colorless liquid used as an amine synergist for type II photoinitiators, commonly used in 1:2 ratio with CQ |
