Ultraviolet Adhesive

This branch of the adhesive world uses acrylics, epoxies and urethanes to achieve the desired results both with the substrates and production process.  UV cured acrylics are generally used for glass bonding while UV urethanes and epoxies are used in the electronic industry to coat circuit boards.  As UV lamps become cheaper, safer and easier to use, the use of ultraviolet adhesives will increase.

Urethanes

One of the most widely used adhesive resins available, urethanes offer an inexpensive solution and additive to many adhesive formats.  Urethanes are available as single component sealers, dual component adhesives, water and solvent base emulsions and adhesives, hot melts, mold making products and high speed laminating adhesives.  The uses are numerous and often impact all areas of production.  Urethanes should be tested as an alternative to many of the products above.

Hot Melt Glue

Hot melt adhesives form a large segment of the adhesive industry and are supplied as a single component material packaged in sticks, chicklets, pillows, slugs, pails, and drums.  These adhesives can be used in a wide variety of applications ranging from labeling to structural automotive bonding to consumer craft glue. The more common hot melts are EVA and PVA and are generally used for medium strength applications while PUR’s (Polyurethane Hot Melts) and Polyamides should be used for any structural applications.
The common applications include form bonding, labels, automotive applications including headliners, seats, dashboards and headlamp assembles.  Application methods can include hot melt glue guns using simple sticks to complicated roll coating dispensing systems for applying a uniform thicknesses.

Peel Stress- In order for peel stress to occur, at least one of the substrates must be flexible.  The stress occurs as the flexible substrate is being peeled or lifted away.

 

Shear Stress- As two bonded substrates are being forced to slide over each other, shear stress occurs.

The stress direction is parallel to the adhesive.  As

shear stress occurs, the ends of the bond resist a

greater amount of the stress than the middle of the

bond.

 
Tensile Stress- This type of stress exerts an equal force over the entire joint.  The direction of tensile stress is straight and apart from the adhesive bond. (Elongation of the object can occur with this type of stress.)

 

Cleavage Stress- This type of stress is concentrated at one end of a joint and occurs when a prying force is placed on the adhesive bond.

 


Compressive Stress- Compressive stress occurs when two substrates are squeezed or pressed together.

Viscosity – the measure of the resistance of a fluid to flow.
Centipoise – shown as cps. Water is the standard by which all fluids are measured.
                    Water is 1 cps @ 70 degrees Fahrenheit.
Thixotropic – this describes a fluid that is gel-like (toothpaste) at rest, but will move with agitation.

Bond Strength

The amount of adhesion between the bonded substrates usually measured in pounds per square inch. The usual test is to bond 1” x 4” coupons with a 1” over lap and pull in a tensile test.

Green Time  (Open Time)

Open time is the time between application and solidification of the adhesive.  During the open time, it is still possible to position parts while being careful not to overlap the open time with the fixturing time of the adhesive.  This will cause an interruption in the curing process and may lead to a less than adequate bond strength.

Cyanoacrylate Ester
This adhesive is supplied as a single component adhesive that cures by way of moisture. The thinner the bead displacement between substrates and the more residual moisture on the substrates equals faster cure times.  These cure times (green strength) may be between 10 seconds and 2 minutes.  Production guidelines as to substrates, fixturing, ambient humidity and bead size are all important in ensuring the most success from this adhesive.  Cyanocrylates tend to bond rubbers very well as Nylon, PVC, EPDM, and most plastics. Some hard to bond plastics such as Polypropylene can be bonded with Cyanocrylates using some of the newer primers.

Acrylics
Commonly supplied either as a two component adhesive in a variety of ratio’s (1:1, 4:1 or 10:1)
Or as a single component with an applied primer. The dual component is used mainly for structural bonding of porous and non-porous substrates and is oil, gas, water and salt resistant.

More common uses are structural bonds of fiberglass, composites, ABS, PVC etc.  The automotive industry is a common user whereas the single component material is generally used in the speaker magnet bonding industry.  Acrylics tend to be very good gap filling, fast curing adhesives that lend themselves well to automated or semi-automated production. These adhesives cure by way of an exothermic reaction and the cost of using this adhesive is medium to high depending on the bead thickness used.

COMMON ADHESIVES QUESTIONS

WEIGHT AND PROPERTIES of Common Materials

Gel Time

The time it takes, (usually in minutes) , for a specific amount of mixed resin and hardener to become unworkable (gelled).

Epoxy

This adhesive is a very common commodity with a vast array of uses.  Epoxies can be used as a single component heat cured product to a dual component adhesive with many different additives.  The uses seem to be unlimited for epoxies and as technology grows so does the use for the adhesives. Epoxies range in cure times from a very fast 3 minutes to a slow cure to 24 hours with hardness and elongation covering a very wide range.  As a true engineered adhesive, epoxies can be altered to fit most any manufacturing need for adhesives.  Costs and packaging are determined by the end use of this adhesive. Common uses are potting compounds, metal bonding, structural bonding and consumer packaged general-purpose adhesives.

AREA

VOLUME

When considering the proper selection of an adhesive, one needs to carefully examine all factors.  One of the most important considerations is the type of stress the adhesive will have to withstand.  STRESS is the force pulling bonded materials apart.

Silicones

Generally used as a sealer or caulking compound, this product also has good adhesion characteristics.  Silicones have an overall moderate strength on most porous to non-porous substrates and generally do not wet out well on polypropylenes or high olefin plastics. Silicones are also regarded as a very good waterproof adhesive that can withstand very low to very high temperatures (-40 to +600 degrees F).  The downfall of silicones is the very long cure time of 2 hours to 48 hours depending on the residual humidity.  The secondary use of silicones is as a 2-component mold-making product.  Silicones offer superior performance with their flexibility and different cure catalysts available.
