Detailed Product Description
Product Description
Technology : Primer - Cyanoacrylate
Chemical Type: Aliphatic amine
Solvent: n-Heptane
Active Ingredient Concentration, %: 0.08 to 0.12LMS
Appearance : Clear colorless liquidLMSS
Viscosity : Very low
Cure: Not applicable

Application:CA Surface Primer
HYBOND770 Primer is used to make polyolefin and other low energy surfaces suitable for bonding with hybond cyanoacrylate adhesives. On such treated surfaces the cured performance of cyanoacrylate adhesives is generally similar to that described in the TDS for the relevant adhesive. It is only recommended for difficult to bond substrates which include polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials. It is not recommended in assemblies where high peel strength is required. HYBOND770 is also suitable for use in the assembly of disposable medical devices.
Typical Properties
Specific Gravity @ 25 °C: 0.68
Viscosity @ 20 °C, mPa·s (cP) : 1.25
Drying Time @ 20 °C, seconds ≤30
On Part Life, hours ≤8

Typical Performance
Fixture time and cure speed achieved as a result of using HYBOND 770 primer depend on the adhesive used and the substrate bonded.

Effect on Cure Speed of Cyanoacrylate Adhesives
HYBOND 770Primer also behaves as an activator and accelerates the cure speed of cyanoacrylate adhesives.Fixturing time on most primed substrates is less than 5 seconds but 24 hours at room temperature (22 °C) should be allowed for adhesive to develop maximum bond strength

Effect on Cured Properties of Cyanoacrylate Adhesives
Products 406, 496 and 868 are based on ethyl, methyl and ß-Methoxyethyl esters respectively. Other liquid products based on these esters will behave in a similar fashion to these examples. HYBOND 770 Primer is not recommended for use with gel products.

Directions for use
Primer may be applied by spraying, brushing or dipping at ambient temperature. Excess primer should be avoided. If polyolefin and more active or easier to bond materials are involved, apply the primer to the polyolefin only.

Handling precautions
Primer must be handled in a manner applicable to highly flammable materials and in compliance with relevant local regulations. The solvent can affect certain plastics or coatings. It is recommended to check all surfaces for compatibility before.

Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Material removed from containers may be contaminated during use. Do not return product to the original container.HYBOND Corporation cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated.
