Hydrophilic coatings enhance the surface properties such that they attract water and appear to smear it out or flatten it. It is useful to be able to control hydrophilicity for a variety of applications. IST offers two main precursors to promote hydrophilicity: mPEG and AETCS.
For a further explanation of the deposition technology and precursors available, consult the brochure below.
AETCS (Acetoxyethyltrichlorosilane) is a mild hydrophilic surface coating. The Acetoxy surface is a polar termination which allows for hydrogen bonding to the hydrophilic surface.
mPEG is a methyl terminated poly ethylene glycol which can be used to create stable hydrophilic coatings. Effective in reducing non-specific binding of proteins, mPEG applications include many biological devices including Bio-MEMS, microfluidic or other surfaces that benefit from a hydrophilic surface.
