NEGATIVE RESIST REMOVER NRR-001

DESCRIPTION:

Negative Resist Remover NRR-001 is a ready to use, low pH formulation composed of a proprietary mixture of aromatic ingredients. NRR-001 is formulated to remove (strip) common negative working photoresists baked onto various substrates (for example, gallium arsenide, silicon, chrome) and is non-corrosive to various metal and oxide surfaces under proper usage. Polyimide is not attacked by NRR-001.

NRR-001 remover does not contain phosphates, chromates, phenol, or chlorinated hydrocarbons. NRR-001 performs well at room temperature or elevated temperatures and exhibits an extended bath life. The shelf-life of NRR-001 is one year when stored in a cool area away from direct sunlight.
