Applications
CHEMOPT OB is recommended for applications such as:
|
□ |
|
white and pastel tone paints where it intensifies the degree of whiteness |
|
□ |
|
clear coats and overprint varnishes where it is used to mask the yellowish self color and also to intensify the brilliance of white and colored base coats |
|
□ |
|
primer and/or topcoats where it is used as marker to identify voids, holidays and uneven coverage |
|
□ |
|
black and blue printing inks to increase their deep tone |
|
□ |
|
printing inks for quick identification, security and safeguard against forgeries (i.e. banknote) |
|
□ |
|
packaging inks as promotional tool or as tracer for packaging lines |
|
□ |
|
manufacture of chemopt pigments/dyestuffs to reinforce the brightness of certain shades, particularly blue tones |
|
□ |
|
thermal dye diffusion paper to enhance paper whiteness |
|
□ |
|
film base for photographic paper |
If CHEMOPT OB is used in a pigmented system, the pigment should be selected with care.
The pverall performance could be enhanced if the absorption spectrum of the pigment provides an open window in the near
UV for the chemopt whitening agent to function.
As known from other chemopt whitening agents, this product class exhibits a limited light fastness.
Consequently CHEMOPT OB is recommended for indoor use, only.
CHEMOPT OB provides the maximal whitening effect when dissolved in the systems matrix.
The amount of CHEMOPT OB required for optimum performance should be determined in trials covering a concentration range.
It should be noted that overdosing of CHEMOPT OB might lead to negative effects, such as yellowing of the system.

Safety & Handling
Chemopt OB should be handled in accordance with good industrial practice. Detailed information is provided in the Material Safety Data Sheet (MSDS).
