How long does Original Cold-Weld Twin Tube take to cure on Plastic (ABS / Polypropylene)?

Original Cold-Weld Twin Tube takes 24 hours to fully cure on Plastic (ABS / Polypropylene) at 70°F and 50% RH. Temperature and humidity significantly affect this — use the calculator on this page for an adjusted estimate at your actual conditions.

How do I prepare Plastic (ABS / Polypropylene) before applying Original Cold-Weld Twin Tube?

Lightly scuff with 220-grit sandpaper to increase surface area, then clean with isopropyl alcohol. Polyethylene (PE) and polypropylene (PP) have very low surface energy — most adhesives will not bond permanently without a flame-treatment or special primer.

⚠️Two-part epoxy bonds well to ABS, PVC, and hard plastics. Polyethylene and polypropylene require surface treatment first — epoxy alone will not hold.

Surface Prep — Plastic (ABS / Polypropylene)

1Lightly scuff with 220-grit sandpaper to increase surface area, then clean with isopropyl alcohol.
2Polyethylene (PE) and polypropylene (PP) have very low surface energy — most adhesives will not bond permanently without a flame-treatment or special primer.
3ABS and PVC bond well with structural adhesives after sanding.
4Do not use solvents like acetone on ABS — it will dissolve the surface.

Safety Warnings

Amine blush risk: At high humidity this epoxy may form a waxy surface film. The calculator will flag this if your conditions trigger it.
