Gluing Nylon

A tough engineering plastic used for gears, cable ties, fixings and printed functional parts.

Also called PA, PA12, PA6, polyamide.

How Nylon behaves when you bond it

Nylon absorbs moisture from the air, and that surface moisture interferes with several adhesive chemistries. Drying the part before bonding measurably changes the result, which is unusual among plastics.

Nylon/polyamide is a tough semi-rigid thermoplastic that absorbs atmospheric moisture and may contain lubricants or glass fibre. Moisture cycling, additive migration and flexibility can undermine bonds that look strong immediately after cure.

Surface preparation

Clean and dry the actual grade; remove processing lubricant with isopropanol if compatible. Drying may improve repeatability for moisture-sensitive systems. Permabond TA4550 is documented for several nylon grades without primer or additional treatment, but other products may need abrasion, treatment or a different moisture condition.

Which adhesives work on Nylon

Excellent

Structural acrylic

Structural acrylic is rated excellent for this material as an application-level assessment, not as a blanket manufacturer claim. Suitability still depends on the other substrate, joint design and service environment.

Good

Polyurethane adhesive

Polyurethane adhesive is rated good for this material as an application-level assessment, not as a blanket manufacturer claim. Suitability still depends on the other substrate, joint design and service environment.

Conditional

Cyanoacrylate

Cyanoacrylate is rated conditional for this material as an application-level assessment, not as a blanket manufacturer claim. Use only after a product-specific test on the actual grade and joint.
