CytoPel coatings selection guide
CytoPel™ is a family of hydrophobic and oleophobic coatings used in a wide variety of applications including microfluidic devices, electronic circuit boards, venting devices, plastic lab devices, etc.
CytoPel 260 is a water based polymer solution for coating porous substrates such as paper. Thin films dry in less than an hour at room temperature and provide a surface with a contact angle to water of approximately 100°. CytoPel 260 is provided at a concentration of 20% and is diluted with water to a final concentration of 1% prior to application.
CytoPel 300 is a polymer in propylene glycol monomethyl ether acetate (PGMEA) for coating glass, plastic and metal. Thin films dry in a few hours at room temperature and provide a surface with a contact angle to water of approximately 105°. Heating will improve speed of film cure. Formulations with fluorescent tracers are available.
CytoPel 400 refers to versions of CytoPel in MEK provided at concentrations between 0.2% and 40%. Thin films dry in a few minutes at room temperature to a surface with water contact angles over 105°. The 400-series is well suited for applications where resistance to sweat, corrosion, tin whiskers and dendrites is needed. Fabrics, mesh, filters and membranes coated with CytoPel 400 retain air permeability, Rayl values, and acoustic penetrance with an oleophobicity grade of up to 6. Please contact Cytonix for custom formulations when solvents such as butyl acetate, ethyl acetate, acetone, or fluoro-solvents are preferred. Versions optimized for greater hardness, flexibility or adhesion to specialty substrates are also available.
CytoPel 500 refers to polymer coating solutions at 0.2% to 20% concentration in solvent. Thin films dry in seconds at room temperature to a surface energy of 6-10 dynes/cm and water contact angles as high as 125°. CytoPel 500 at 2-3% is particularly well suited for coating membranes and provide an oleophobicity grade of 8. The no charge addition of silane adhesion promoter is recommended for application to oxide surfaces. CytoPel 500 polymers can be optimized for adhesion to a variety of substrates such as plastics, fiberglass, metal, ceramics and glass. CytoPel 500 solutions may be applied by a number of methods including dipping, brushing, damming, dripping, capillary, slot-die, or syringe dispensing. The 500 series is well suited for applications such as conformal coatings, microfluidic devices and dry-lubricant applications. CytoPel does not occlude pores and helps achieve high oleophobicity grades.
CytoPel 1101AC, 1102AC and 1104AC are one, two and four percent polymer solutions in a high boiling point solvent (BP=135°C). Thin films dry in a few hours at room temperature to a surface energy of about 10 dynes/cm. Warming to 100°C for 10 minutes optimizes adhesion and reduces the surface energy to about 6 dynes/cm. 1100-series solutions are recommended for spray, spin, and slot-die application. Polymer options that have good adhesion to plastics, glass and metals are available.
CytoPel 1601AC, 1602AC and 1604AC are one, two and four percent fluoropolymer solutions in high boiling point solvent (BP=160°C). Thin films dry in 2-3 hours at room temperature to a surface energy of about 10 dynes/cm. Warming to 150°C for 10 minutes optimizes adhesion and reduces the surface energy to about 6 dynes/cm. The preferred methods for the application 1600-sereis is by spray, brush, ink jet, pad-print or spin.
FluoroPel 1601V, 1604V and 1610V are one, two and ten percent FluoroPel V-polymer solutions in a high boiling point fluorosolvent (BP=160°C). Thin films are generally applied by spinning for 30 seconds at 3000 rpm and curing at 80°C for 20 minutes plus 150°C for 30 minutes. The no charge addition of 2 percent fluorosilane (PFC 1601V-FS) is recommended for adhesion to oxide surfaces such as glass. FluoroPel is one of the coatings recommended by OpenDrop, which is a digital electrowetting device lab-automation community derived from hackteria.org.
FluoroPel 1101V is a one percent FluoroPel V-polymer solution in a 110°C boiling point fluorosolvent. Thin films are generally applied by spinning for 30 seconds at 2000 to 3000 rpm and curing at 80°C for 20 minutes plus 100°C for 30 minutes. The no charge addition of 2 percent fluorosilane (PFC 1101V-FS) is recommended for adhesion to oxide surfaces such as glass.
