Applications & Uses

Additional Information

Technical User Information:

Cyanoacrylates are fast setting, one component, and solvent-free adhesives.
Polymerization is initiated by present humidity. Best results are given between 40 to 70% relative humidity and 20 to 24 °C ambient temperature.

Processing Information:

Surfaces should be clean and free from grease.
Dispense adhesive to one surface only. Apply only enough to leave a thin film layer after compression.
Press parts together and hold firmly until the adhesive has fixtured. Maximum strength is attained typically in 24 hours. The product should be allowed to develop full strength before subjecting it to any service loads.

Clean Surface

The surface condition of the mating parts has an enormous influence on the success of a bond. To achieve good bonding success the mating parts should be clean.

LINOP Equipment

Cyberbond offers by means of the LINOP Equipment range suitable dosing and LED based curing devices. We also refer to suitable dosing tips which help an economical use of the adhesives (also if used manually).

Features & Benefits

Product Highlights

Cyanoacrylates are fast setting, one component and solvent free adhesives. They are based on esters of cyanoacetic acid. To get to a finished product, mainly thickeners, respectively film forming agents (polymer methacrylics and acrylics) and stabilizers are added. The polymerization is initiated by present humidity. Best results are given between 40 to 70 % relative humidity.

Cyberbond standard grades are as follows:

Powerdrop series (stabilized ethyl ester)
Elastomer and plastic series (ethyl ester)
Neomer Series (surface insensitive ethyl ester)
xtraflex series (rubber toughened ethyl ester)
metal series (ethyl ester)
low odor series (alkoxy ester)
medical series (butyl- and octyl ester)

Safety & Health

Potential Danger of Cyanoacrylates

You should care for the following:

Use in well ventilated areas only
Installll suitable exhaust systems in the workshop
Apply material economically and use a dosing system where appropriate
Allow a consistent relative humidity of 50 to 65 %; with regards to lower figures the polymerization will be delayed and monomer adhesive fume will appear
If necessary: wear suitable, non-sucking gloves (Eg. No cotton)
Keep adhesive out of reach of children

The data mentioned in this TDS, particularly the recommendations and use of products are based on our recent knowledge and experience. Due to the fact of having so many different materials involved and conditions of applications which are out of our influence, we strongly recommend to do sufficient tests in order to guarantee that Cyberbond products are suitable for the intended process and applications. Except for wilful acts any liability based on such recommendations or any verbal advice is hereby expressly excluded.

Technical Details & Test Data

Measurement of Viscosities

Viscosity describes the flow-ability of a liquid. Cyberbond measures the viscosity of the products by means of the cone/plate method: the liquid is applied on a panel and a defined cone presses the liquid together and rotates. You differentiate between a Newtonian and a thixotropic liquid. In terms of a Newtonian liquid you will get a relative constant viscosity graph in dependence of the rotary speed of the cone. In terms of thixotropic liquids the product becomes more liquid (down to its base viscosity) the faster the cone rotates. The viscosity is measured in mPa*s (milli Pascal x second) [SI system] or in cP (centipoise) [CGS- system]; 1 mPa*s = 1 cP. In order to allow products comparison all adhesives are measured at the same rotation speeds.

Newtonian liquids at 160 upm
Thixotropic liquids at 0,5 upm and at 160 upm

Temperature always is at 20 °C / 68 °F, if not mentioned to be different.
