Fluoro-Silanes
Anti-Fingerprint Fluoroalkyl Silane (C10, Methoxy) | Manta F1731
Manta F1731 is 1H,1H,2H,2H-perfluorodecyltrimethoxysilane (CAS 83048-65-1), a long-chain fluoroalkyl silane that bonds covalently to hydroxyl-containing substrates to form a low-surface-energy, water- and oil-repellent layer, used in anti-fingerprint coatings for displays and lenses, precision optics and sensors, and nano-imprint release coatings.

Overview
Manta F1731 is a reactive fluoroalkyl silane with a long fluorinated carbon chain, designed to create durable, low-surface-energy coatings by bonding covalently to hydroxyl-containing substrates. Treated surfaces show anti-fingerprint, easy-to-clean and anti-contamination performance.
F1731 carries methoxy groups and releases methanol on hydrolysis. Manta F1732 carries the same fluoroalkyl chain with ethoxy groups and releases ethanol.
Long-chain fluoroalkyl substances with a C8F17 group are subject to strict controls. The EU POPs Regulation (EU) 2019/1021 and national rules under the Stockholm Convention cover PFOA-related compounds. Availability depends on destination and end use and is confirmed at inquiry; check that your intended use is permitted before formulating.
Key Features
- Long fluorinated chain for low surface energy

Frequently Asked Questions
How does Manta F1731 differ from Manta F1732?
Both carry the same long fluoroalkyl chain. F1731 has methoxy groups and releases methanol on hydrolysis, while F1732 has ethoxy groups and releases ethanol. The choice depends on the by-product your process can accept and on how the coating is applied.
Which regulations apply to Manta F1731?
F1731 carries a C8F17 fluoroalkyl group, and PFOA-related rules can apply, including the EU POPs Regulation (EU) 2019/1021 and national rules under the Stockholm Convention. Whether the grade can be supplied depends on the destination and end use. Contact us with both before planning a formulation.
