[mems-talk] Developer for Polyurethane Oligomer Mixture

[Kelly Goss]

Hello,

There is a very specific resin that I woul like to integrate into a 
photolithography process; however, the supplier is unable to suggest a 
developer.  The composition of the resin is:

Polyurethane Oligomer, 20-25%
High Boiling Acrylate, 30-35%
High Boiling Methacrylate, 5-10%
Aliphatic Amide, (CAS #  2680-03-7), 7-12%
High Boiling (Meth) Acrylate, 1-5%
Photoinitiator, (CAS # 947-19-3), 2-5%
Acrylic Acid, (CAS # 79-10-7), 3-7%

I would appreciate any suggestions of developers or methods of 
determining what kind of developer to use.

Thanks,

Kelly Goss
