Clog‑Free Cyanoacrylate & Low‑Viscosity Fluid Application

A PTFE‑lined dispensing tip is the recommended choice for applying Cyanoacrylate (CA) adhesives and other low‑viscosity liquids. PTFE is a non‑stick, chemically inert material that prevents premature curing, moisture reaction and clogging inside the tip. By reducing blockage, PTFE‑lined tips last longer, improve deposit consistency and significantly reduce consumable costs.

PTFE‑lined tips are available in a wide range of diameters, lengths and shapes, allowing you to select the exact configuration required for your application. Higher‑viscosity adhesives benefit from larger‑diameter PTFE‑lined tips, while low‑viscosity adhesives require small‑diameter tips for controlled flow.

Why PTFE‑Lined Tips Prevent Clogging

Cyanoacrylates cure when exposed to moisture. Standard metal tips can trap trace moisture or react with the adhesive, causing premature curing, irregular bead formation and downtime. A PTFE liner eliminates these issues by providing a non‑reactive, moisture‑resistant internal surface.

The PTFE tube extends 1/8" beyond the stainless steel shaft to protect sensitive substrates from scratching and ensure smooth, controlled deposits.

Recommendations for Dispensing Cyanoacrylate Adhesives

• Use a tip with an inner diameter similar to the bead size required.
• Apply light, controlled pressure (pneumatic, manual or electric peristaltic pump).
• Dispense in a well‑ventilated area or use basic fume extraction.
• Wear gloves and eye protection to avoid contact with adhesive.
• Use Adhesive Dispensing Ltd debonder liquid to remove CA from skin or surfaces.

Construction & Compatibility

PTFE‑lined tips attach securely to syringe barrels, dispensing valves and bottles using a luer lock thread. The PTFE tube is crimped to the stainless steel shaft to guarantee consistent liquid flow and prevent liner movement.

All PTFE‑lined tips are:

• Industrial grade
• Silicone‑free
• Safe for use up to 100 PSI
• Suitable for Cyanoacrylate gels and thin liquids
• Compatible with low‑viscosity anaerobic adhesives

The PTFE surface reduces outlet curing and provides superior control for microscopic dots, thin beads and precision micro‑applications.

Adhesive Dispensing Ltd provide a wide range of equipment options for dispensing almost all assembly fluids – from watery liquids, solvents, primers and activators through to thick pastes, sealants, silicones, gels and epoxies.
