Bis(2,4,6-trimethylbenzoyl)phenylphosphine oxide

 

PowerCure™ 819

CAS No. 162881 26 7

Bis 2 4 6 trimethylbenzoyl phenylphosphineoxide

 

PowerCure™ 819 is a versatile photoinitiator for radical polymerisation of unsaturated resins upon UV light exposure. It is especially suited for white pigmented formulations, the curing of glass fiber reinforced polyester/styrene systems and for clearcoats for outdoor use in combinations with light stabilizers. Thick section curing is also possible with this photoinitiator.

 

Benefits & Applications of PowerCure™ 819 cas 162881 26 7

 

PowerCure™ 819 may be used in UV curable formulations for clear and for pigmented coatings on wood, metal, plastic, paper and optical fibers as well as for printing inks and prepregs after adequate testing.

 

PowerCure™ 819 exhibits at low concentrations an outstanding curing performance in highly opaque white and colored furniture coatings or screen inks containing rutile titanium dioxide or colored pigments and affords minimum yellowing after exposure to sufficient amounts of UV radiation. In addition, the outstanding absorption properties of this product allow curing of thick sections.

 

PowerCure™ 819 can be used in combination with other photoinitiators such as PowerCure™ 184 and it is especially suited to cure polyester/styrene resins as used for glass reinforced materials with some photoinitiators.

 

PowerCure™ 819 can also easily be used in combinations with UV absorbers due to its photosensitivity at longer wavelengths. This type I photoinitiator is therefore ideally suited for use in weather-resistant UV curable coatings.

 

The amount of PowerCure™ 819 required for optimum performance should be determined in trials covering a concentration range.

Benzophenone UV Absorber

Image
  Benzophenone UV  absorbers are general purpose UV absorbers commonly used in polyolefin applications and can be incorporated into a range of polymer products. These benzophenone UV absorbers have good absorption in the wavelength range from 260 to 350 nm and are stable throughout processing.   Benzophenone UV absorber s have excellent compatibility with various resins and are widely used not only as plastic additives but also in applications such as coatings and synthetic resin adhesives.   Benzophenone UV absorbers provide protection for thick and thin sections and are optimized when used in unpigmented or lightly tinted formulations. When used in combination with hindered amine light stabilizers (HALS), the benzophenone UV protection can be improved, especially when stabilizing thin sections.   Since 1989, TINTOLL has actively participated in the development of innovative light stabilizers and application research, and currently has more than 100 specialty p...
