Instant Adhesives

There is an Aron Alpha® adhesive suitable for instantaneous and permanentbonds to almost all materials, Aron Alpha® adhesives are composed of alphacyanoacrylate monomers (liquid state). When this adhesive is spread thinly onthe surfaces to be bonded, the small quantity of moisture on the surface acts asa curing agent, rapidly turning the monomer into a solid polymer and bonding thematerials.

Instantaneous Adhesion

• Strongly bonds materials in seconds• Optimum adhesives for mass production• Various setting times available to suit your

application

Strong Bonding Power

• Uniquely suited for bonding small areas• An adhesive available for almost any material• Special primers allow bonding of inert plastics

(PP, PE etc.)

One Component

• No curing agent needed• No metering of two-components

AA Setter (Cure accelerator)

AA Setter accelerates the bonding reaction of Aron Alpha® cyanoacrylateadhesive. Use AA Setter to shorten the setting time, to bond porous materials, to fill gaps, or to prevent blooming or chrolosis.

PP Primer (Adhesion promoter)

Polyolefin plastics such as polypropylene and polyethylene are generally considered difficult-to-bond materials, PP Primer has been specifically developed to allow these materials to be bonded with Aron Alpha® adhesives. Applying PP Primer to polypropylene and polyethylene before use of Aron Alpha®

cyanoacrylate will result in a strong, longlasting bond.

How to Apply Aron Alpha®Adhesives

1. Remove oil, grease, rust, release agents, or other residues on the surface to be bonded.

Degrease with a suitable solvent (See Technical Bulletin). Remove rust and other solid residues withsandpaper (Strength of bonds on painted surfacesare limited by the bonding strength of a paint to the substrates).

2. Personnel applying adhesive should wear goggles and polyethylene gloves to prevent accidental bonding of fingers and spraying of adhesives into eyes. The surfaces to be bondedshould be dry, and at or above 20℃ . A relative humidity below 50% gives best results. Ventilation to remove fumes is desirable.

3. Detach cap. Flick tip of bottle to remove adhesive from puncture area. Make a small hole in the nozzle.

4. Apply Aron Alpha® adhesives as drops or a ribbon on only one of the surfaces to be bonded. Normallychoose the smaller surface, or the surface onwhich the time set is longer, and if possible, theupward facing surface. Closely fit the two surfaces to be bonded so that the adhesive spreads betweenthe surfaces. When it is difficult to position the twosurfaces because of the short set time, consider using penetration bonding (mate surfaces and apply drop of adhesive to crack, allowing capillary actionto spread adhesive) or choose a slower setting typeof Aron Alpha® adhesives.

5. Use as little Aron Alpha® adhesives as possible.Surface moisture catalyzes the curing of theseadhesives, so only a thin film between the surfacesto be bonded is desirable. The optimum applicationquantity on non-porous surfaces is 5-6mg/cm2.

6. The setting time varies with the materials to bebonded, the surface conditions, temperature andhumidity. However, bonding will be completed fromwithin a few seconds to a few minutes at the longest.(Maximum strength will be attained in 12 to 24 hours.)

Care in HandlingFactors to Consider in Choosing & Applying Aron Alpha® Adhesives

• Bonding Surfaces

Close fitting, non-porous surfaces give the bestbond. Avoid loose fitting surfaces and wide gaps.A clearance of 0.02 – 0.03mm between the bondedsurfaces is ideal. A slightly rough (fine to mediumfile) surface produces the strongest bond. Forporous surfaces or slight gaps consider a higherviscosity Aron Alpha® adhesives. Acidic surfacessuch as chrome plating must be neutralized forproper adhesive curing.

• Plastic Cracking and/or Dissolution

Some plastics swell and crack, or dissolve when exposed to cyanoacrylate monomers for an extended period. Avoid this by using the fastestsetting type of Aron Alpha® adhesives as possible,applying only a thin layer of the adhesive(a thick layer slows down the setting time), andapplying an AA Setter, if necessary.

Plastics apt to be affected include:- AS, PS, ABS- Cellulose- Polycarbonate resins- Polymethyl methacrylate

• Bond Small Areas

Fast setting Aron Alpha® adhesives are notsuited for application on large areas. Theadhesive may set before the parts are joined.Consult the Setting Time chart to determinewhich adhesives are usable for your application.Spot bonding with Aron Alpha® adhesives maybe used to supplement slower drying and weakeradhesives applied to large areas, providingstronger bonds at critical points and for reducingclamping times.

• High Temperatures

At temperatures above 80℃ most Aron Alpha®

adhesives will lose bonding strength. 400 series isdesigned to retain bonding strength at temperatures up to 120℃.

• Impact Strength

Aron Alpha® Adhesives have high tensilestrength, but comparatively poor resistanceto peeling or impact loads. Design areas ofadhesion to minimize peeling or impact loads(tongue and groove joints, rubber inserts, sleevejoints, etc.). 400 series adhesives have up to 3times the impact resistance of other Aron Alpha® adhesives and should be considered whereimpact resistance is a factor.

• Chlorosis

A white impalpable powder resin is generatedwhen part of the Aron Alpha® liquid (monomer)volatizes from the bonded areas, polymerizes inthe adjacent air and attaches to the immediatearea. This phenomenon is apt to take placewhen materials are bonded in a very humidatmosphere or the bonded materials are packedin containers immediately after bonding. To prevent chlorosis:

- Do not use excessive amounts of the adhesive.

- Keep the environment dry and temperatures at 20℃ or higher.

- Disperse the volatized monomer with a fan or ventilator.

- Use an AA Setter to speed curing.- Use Aron Alpha® 800 series, specially

formulated to minimize chlorosis.

If chlorosis occurs, remove the deposit with adry cloth, or use a solvent that will not dissolvethe substrate (plastic). See Technical Bulletin.

• Skin

Aron Alpha® may instantaneously bond yourskin. If your fingers have been bonded with AronAlpha®, do not try to pull them apart vigorously,but rub the fingers in warm water, a releasingagent, acetone or other solvents. The fingers canalso be pulled apart gradually.

• Eyes

If Aron Alpha® contacts your eyes, immediately wash the eye with lots of water and seek medical care. (Never use solvents nor rub theeye with your finger.)

• Babies and Children

Aron Alpha® has a very strong bonding power.Keep away from babies and children.

• Ventilating

Aron Alpha® in the liquid state has a slightly irritating odor. When a large quantity of Aron Alpha® is used, it is desirable to keep the roomwell ventilated.

• Exothermic reaction

Aron Alpha® will produce exothermic reaction when it is polymerized (resinified).

The exothermic reaction is particularly strongwhen a lot of Aron Alpha® monomer permeatesa porous material such as a woven cloth orurethane rubber and then quickly solidifies. Ifan accelerator such as caustic soda or amineis contained in such materials, the exothermicreaction will take place and can give off sufficientheat to cause burns.

How to Store Aron Alpha®

• Humidity

Aron Alpha® turns into a resin when it comesinto contact with even a very small quantity ofmoisture and therefore care should be taken toavoid storing Aron Alpha® in a moist or humid environment. Be sure to fasten the cap to thecontainer tightly. Store Aron Alpha® with adesiccant in an airtight box. It is not desirable toarbitrarily expose Aron Alpha® to the open air.

• Sun rays

Aron Alpha® turns into a resin when exposed toultraviolet rays. Do not expose Aron Alpha® todirect sunlight.

• Temperature

When stored at high temperatures, Aron Alpha® begins to lose its original bonding strength.It is advisable to store Aron Alpha® at as low a temperature as possible. When storing Aron Alpha® or an extended period, it is recommended to keep it refrigerated between 5℃ and 10℃.

• Other

Never store Aron Alpha® together with anAA Setter.
