Printing and Striping Inks
High Temperature Striping Inks
|
These are aqueous striping inks used for striping or printing high temperature resins. They
feature a high temperature resin binder to hold the pigment in place after sintering and are
sold as water dispersions with very low VOC content. There are three families of high
temperature striping inks:
PTFE Striping Inks
|
|
|
For striping or top coating PTFE insulated wires or tubing
Because of the thermal similarities of the PTFE and PFA, these
can also be used on PFA substrates
|
|
FEP Striping Inks
|
|
|
For striping or printing on insulated wires or tubing
For use on FEP, PFA, PTFE substrates
|
|
|
Polyimide Striping Inks
|
|
|
For striping or printing on insulated wires or tubing
For us on KaptonŽ or PEEK substrates
|
Low Temperature Striping Inks
|
These are aqueous striping inks used for striping or printing lower temperature substrates. They
feature a synthetic resin binder to hold the pigment in place after sintering and are sold as
water dispersions with very low VOC content. These should be used on ECTFE, ETFE or PVDF
substrates.
|
NMP pigment dispersions for Pyre-ML® and polyimide
|
These are hydrocarbon solvent based pigment systems used to color top coats on polyimides, such
as the aromatic polyimide wire insulation enamels sold under the Pyre-ML® tradename by the IST
Corporation. These enamels feature 240° C service temperatures, excellent chemical
resistance and are commonly used to insulate transformer and motor wires.
|
Processing
|
Striping inks are applied most often by brushing on the substrate followed by a sintering step
to drive off the water and bind the pigments to the surface. In some cases with Low Temperature
Striping Inks, it is advisable to heat treat the substrate prior to application.
For additional processing information and let down suggestions, please refer to the specific
data sheets for each of these product families available from your local sales office or this
website.
