Dental Photoinitiators

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
Camphorquinone
Absorption Range:  400-550 nm, 470 nm peak

Description:  Type II, fine yellow powder, very common and effective for dental restoratives, heat aids in dissolution

PL-TPO
2,4,6-Trimethylbenzoyl-diphenylphosphine oxide
Absorption Range: 230-430 nm, 385 nm peak

Description:  Type I, off-white, crystalline powder, dissolves in most monomers, exhibits photo-bleaching properties

PL-PPD
1-Phenyl 1,2-propanedione (PPD)
Absorption Range:  300-480 nm, 393 nm peak

Description:  Type II, yellow liquid, believed to have a lower rate of polymerization that is not detrimental to overall conversion

PL-EDB
Ethyl-4-dimethylamino benzoate
(EDAB, EDMAB)

Description:  a tertiary amine synergist typically used in combination with type II photoinitiators such as PL-CQ

X-866-0000
Dihydroxyethyl-para-toluidine
(DHEPT)

Description:  solid, off-white amine co-initiator that is low in color, requires melting or crushing to simplify incorporation

X-867-0000
2-dimethylaminoethyl methacrylate
(DMAEMA, MADAME)

Description:  a clear, colorless liquid used as an amine synergist for type II photoinitiators, commonly used in 1:2 ratio with CQ
