About ADINOX 770 — Adhesion Promoter and Cyanoacrylate Primer for Plastics
Target Substrates for the ADINOX 770 Adhesion Promoter (Polyolefin Primer) — Where Standard Cyanoacrylates Cannot Bond
- Polyethylene (PE) — HDPE, LDPE, LLDPE components
- Polypropylene (PP) — automotive, packaging, industrial parts
- PTFE (Teflon®) — tubing, seals, gaskets
- Thermoplastic Rubber (TPR/TPE) — flexible parts, grips, seals
Not recommended for applications requiring high peel strength, regardless of substrate.
ADINOX® 770 is an adhesion promoter (primer) designed for use with ADINOX C Series cyanoacrylate adhesives on polyolefins and other low surface energy substrates. It is the recommended solution for bonding polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), and thermoplastic rubber (TPR) — materials where standard cyanoacrylates cannot form a reliable bond without surface treatment.
As a polyolefin primer and cyanoacrylate primer for plastics, this adhesion promoter is applied before the adhesive: ADINOX 770 dries in 30 seconds and keeps the treated surface active for up to 6 hours, giving the operator a wide work window. It is a UV detectable primer at 365 nm, enabling quality-control verification in production.
Key Advantages — UV Detectable Primer with a 6-Hour Work Window
- Dry time: 30 seconds — fast treatment, minimal production downtime
- On-part life: 6 hours — treat multiple parts in advance for batch bonding
- Full cure after adhesive application: 24 h at 71°F
- UV-detectable at 365 nm — verify primer coverage in quality control inspection
- Single coat recommended — multiple coats may reduce adhesion performance
- Application: spray, brush, or dipping
One-Surface or Two-Surface Application — Depends on Substrate Combination
- Both surfaces are polyolefin: apply ADINOX 770 to both surfaces
- Only one surface is polyolefin: apply primer only to the polyolefin surface; apply adhesive to the untreated surface
- If more than 6 hours have elapsed since primer application, reapply before bonding

How to Use ADINOX 770 Adhesion Promoter
Apply an even coat of ADINOX 770 to the polyolefin surface by spraying, brushing, or dipping. A single coat is recommended — multiple coats may reduce adhesion performance.
Allow approximately 3 minutes for the primer to dry before applying the adhesive. The surface is now active for up to 6 hours.
Apply the ADINOX C Series cyanoacrylate adhesive to the primed surface. Complete the bonding operation immediately after adhesive application.
If both surfaces are polyolefin, apply ADINOX 770 to both. If only one surface is polyolefin, apply primer only to that surface. Apply adhesive to the untreated surface.
If more than 6 hours have elapsed since primer application, reapply ADINOX 770 before proceeding with bonding.
Storage: Store in original closed container at 46–71°F, max 82°F. Protect from direct sunlight, heat, moisture and UV radiation. Flash point 25°F — store away from heat, sparks and open flames.

Frequently Asked Questions — ADINOX 770 Adhesion Promoter
What is an adhesion promoter and how is it different from a primer?
The terms are used interchangeably in the industry. An adhesion promoter or primer is a chemical treatment applied to a substrate surface to increase its surface energy and allow bonding with adhesives that would otherwise fail. ADINOX 770 is specifically formulated for polyolefins (PE, PP, PTFE, TPR) and cyanoacrylate adhesives.
Should ADINOX 770 be applied to both surfaces or only one?
If both substrates are polyolefins, apply ADINOX 770 to both surfaces. If only one substrate is a polyolefin, apply the primer only to that surface and dispense the adhesive on the untreated side.
How long should ADINOX 770 dry before applying the cyanoacrylate?
Allow approximately 3 minutes for the primer to dry before applying the ADINOX C Series cyanoacrylate. Once dry, the treated surface remains active for up to 6 hours.
Does the ADINOX 770 adhesion promoter work for bonding polypropylene?
Yes. Polypropylene (PP) is one of the primary target substrates for ADINOX 770. It is a low surface energy polyolefin that standard cyanoacrylates cannot bond reliably without surface treatment. Apply ADINOX 770 to the PP surface, allow 3 minutes to dry, then apply the ADINOX C Series cyanoacrylate within 6 hours.
Why is the 6-hour on-part life of ADINOX 770 important for production?
The 6-hour on-part life means that treated parts can be pre-primed in advance and then bonded at any point within that window — without needing to reapply the primer between each bonding cycle. This is a significant advantage for batch manufacturing where parts are primed at one station and bonded at another. If the window is exceeded, simply reapply ADINOX 770.
What does the UV-detectable feature of ADINOX 770 mean for quality control?
ADINOX 770 contains a UV-fluorescent compound that makes the primer visible under a 365 nm UV inspection lamp. This allows quality control personnel to verify that the primer was applied and covers the entire bonding area before the adhesive is applied — catching missed surfaces before they become bonding failures in the field.
Can ADINOX 770 be used for high peel strength applications?
No. ADINOX 770 is not recommended for applications requiring high peel strength. Cyanoacrylate adhesives — even with a primer — are inherently low in peel resistance. For applications with peel or flexural loading, consider ADINOX C388 (rubber-toughened) or contact an ADINOX distributor to evaluate the right adhesive system for your assembly.
What is the correct storage temperature for ADINOX 770?
ADINOX 770 should be stored at 46–71°F, with a maximum of 82°F. Keep in the original closed container, away from direct sunlight, heat, moisture, and UV radiation. Do not return unused product to the original container. Important: ADINOX 770 has a flash point of 25°F — it must be stored as a highly flammable liquid, away from heat, sparks, and open flames.
