Mxbon 214204 High Performance

The rate of cure can be affected by temperature, humidity, the smoothness of the surface, the closeness of the surface and specific surfaces being bonded. Although full functional strength is developed in a relatively short time, curing continues for at least 24 hours before full chemical/solvent resistance is developed.

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. Acidic surfaces such as paper and leather may have longer cure times than most plastics and rubbers. Some plastic with very low surface free energies, such as polyethylene, polypropylene, PTFE and silicone rubber may require the use of a primer. The table below shows the fixture time achieved on different materials at 25℃/50% RH. This is defined as the time to develop shear strength of 0.12 N/mm2 (1.2 kgf/cm2 ) and the strength keeps at least 10 seconds.

Bonding Identical Substrate	Fixture time , seconds
Mild steel	120 to 150
Aluminum A5754	5 to 10
ABS (Acrylonitrile Butadiene Styrene)	25 to 40
PVC(Polyvinyl chloride)	150 to 180
PC(Polycarbonate)	45 to 55
Oak wood	40 to 60
Pine wood	70 to 90
Beech wood	40 to 60
NBR(Nitrile-Butadiene Rubber)	10 to 30
Paper	<5

Cure Speed vs. Bond Gap

The rate of cure will depend on the bond line gap. A thinner bond line will give faster polymerization and a strong bond. Largebond gaps will result in a slower cure and lower bond strength. Cartell Activator may be used to increase cure speed.

Cure Speed vs. Activator

Cartell Cyanoacrylate Activators may be used in conjunction with Cartell Cyanoacrylate Adhesive where cure speed needs to be accelerated. Cure speeds of less than 2 seconds can be obtained. The use of an activator may reduce the final bond strength. If bond strength is critical testing on the parts is recommended to measure the effect. When using the activator apply it to one side of the bond and the adhesive to the other.

Additional information

This product is not recommended for use in contact with strong oxidizing materials and polar solvents although will withstand a solvent wash without any bond strength deterioration. Users are reminded that all materials, whether innocuous or not, should be handled in accordance with the principles of good industrial hygiene. Full information can be obtained from the Safety Data Sheet (SDS).

Directions for use:

1) Make sure the surfaces to be bonded are clean, dry and grease-free before applying the adhesive.

2) Dispense a drop or drops to one surface only.

3) Bring the components to together quickly and correctly aligned.

4) Apply sufficient pressure to ensure the adhesive spreads into a thin film.

5) Do not disturb or re-align until sufficient strength is achieved, normally in a few seconds.

6) Any surplus adhesive can be removed with solvent, such as nitromethane or acetone.

7) Because Mxbon® 214204 condenses by polymerization, sometimes blooming will occur on the surface of the container or the bonded materials. Should this happen, wipe surface well with acetone or nitromethane.

8) Product should be allowed to develop full strength before subjecting to any service loads (typically 24 to 72 hours after assembly, depending on bond gap, materials and ambient conditions).

Storage

Keep in a cool area out of direct sunlight. Refrigeration to 2-8℃ gives optimum storage stability. When stored in a refrigerator, allow the adhesive to gradually warm to room temperature prior to use. It will prevent condensation inside the bottle which can reduce shelf life. Containers should be tightly sealed when not in use. Product removed from containers may be contaminated during use. Do not pour back any product to the original container. Misuse of product will void all warrantees. The shelf-life is 18 months from date of manufacture.
