TFM 100

FluoroPel TFM-100 for plastic devices is a fluoroacrylic copolymer solution in a fluorosolvent for coating plastic devices such as pipette tips, tubing and micro-centrifuge tubes. Thin films dry in a few minutes at room temperature to provided water contact angles greater than 110°. Contact angles to mineral oil is greater than 75°. This version of FluoroPel is primarily applied by dip coating. This coating is used in dip coating machines to make laboratory devices such as pipette tips low retention. These assist in preventing water, oil, buffers, solvents, biological-fluids and other materials from sticking to laboratory devices. FluoroPel is used for industrial, research and medical applications.

TFMA

FluoroPel TFMA is a fluoro surfactant dry melt additive for plastic devices such as pipette tips, tubing and micro-centrifuge tubes. The surfactant blooms on the device to provide water contact angles greater than 110 degrees. Contact angles to mineral oil is greater than 75 degrees. TFMA is compounded into polypropylene at 0.5% to make pipette tips and other plastic devices water, oil and organics repellent. TFMA prevents water, oil, buffers, solvents, biological-fluids and other materials from sticking to device surfaces. TFMA is used in industrial, research and medical applications.
