Abstract
PFAS compounds provide surface tension (ST) reduction, coefficient of friction (COF) reduction, hydrophobicity, oleophobicity and chemical stability.  These fundamental properties result in applications such as stain resistance, block resistance, oil resistance, lubricity, release, AFFF and many others.  
Siltech have presented previously on replacing PFAS components with organomodified silicones which provide similar and satisfactory performance on ST, COF and hydrophobicity. The difficult challenge is oleophobicity. We have had some success in this category and will report this here. We will emphasize some UV cured acrylate structures which are giving strong performance in this critical category.
