  3. At what wavelength does Product 651796, Negative photoresist, have absorbance?

    This product has a spectral absorbance range of 310-480nm. The peak spectral sensitivity is around 355nm.

  4. How should Product 651796, Negative photoresist, be stored?

    It should be refrigerated to inhibit polymerization and warmed to room temperature before opening.  It should also be stored away from light sources and kept in the sealed bottle.

  5. How do I use Product 651796, Negative photoresist?

    Please refer to technical bulletin AL-217 for detailed procedures.

  6. When using Product 651796, Negative photoresist, how do I remove the photoresist film?  

    Hot chlorinated hydrocarbons such as those in Product No. 651761, Negative Resist Remover I, swell the photoresist, which effectively removes the resist film.  The ideal temperature at which to use the remover is 50-60°C.

In alkane solvents, poly(isoprene-b-ferrocenyldimethylsilane) (PI-b-PFS) block copolymer forms fiberlike micelles, which show intriguing similarities with biological fibers such as amyloid fibers. Both systems exhibit fiber growth by a nucleated self-assembly mechanism and rapidly fragment upon exposure to the shear forces
