Description | Purchase Information 


M.M.R.C. provides a wide range of photolithography chemicals. This includes materials from the Kayaku range of chemically amplified expoxy based negative photoresists, Lift Off resists, PMMA / Co Polymer positive resists developers and ancillary chemicals from our partners, Kayaku, in the United States.

We can supply these resists in small bottle sizes to suit the R&D users. Most products can be supplied beginning with 500mls, 1 litre, and 4 litres bottles. Hence, end users can minimise any excessive wastage associated with unused or expired resists purchased in larger bottle sizes.

  • Dilutions.
  • Dye addition.
  • PAG adjustments.
  • Solvent Mixtures

The range includes the following product series:

SU-8 & KMPR Photoresists
