Structural Adhesive

Everything You Need to Know About Structural Adhesives

What is a Structural Adhesives?

There is a common misconception that sealants and structural adhesives are the same, but that couldn’t be further from the truth. A structural adhesive cures, or hardens, and permanently bonds the two pieces. A sealant, on the other hand, acts as a filler instead. That filler can eventually deteriorate and need replacing, whereas a structural adhesive should never need to be replaced.

With structural adhesives, there is more than one type. In fact, there are seven different types that you can choose from, depending on the project at hand. The seven structural adhesives include vinyl acetates, epoxies, anaerobics, phenolics, toughened acrylics, cyanoacrylates, and polyurethanes.

There are many benefits to using structural adhesives, and they include impact resistance, aesthetics, strength, efficiency for any process, design innovation, lightweight options, water resistance, and bonding between almost any material. Of course, to receive these numerous benefits, you must know the answers to specific questions before applying the structural adhesive.

Questions Before Applying Structural Adhesives
• How hot or cold is the temperature where the job is being performed?
• Will the material that you are working with ever have exposure to saltwater or rain? How about the sun?
• Will any chemicals come into contact with the joint after using the structural adhesive? How about oil, gas, or other types of fuel?
• How often will the joint be cleaned using detergents?
• Are you trying to bond a device in the medical field? Is there concern for any toxicity levels?
• What are the stresses on the joint? Is the stress level higher than average?
• Will the joint you are working on be subject to vibrations or high levels of impact?

Once you know the answers to these questions, you can successfully choose a structural adhesive that meets your needs. Epoxies usually are better for metals, strength, and temperature resistance, while acrylics are suitable for plastics and shear metals. Urethanes are best for flexibility, unlike cyanoacrylates, which are typically used the most for plastics and metals that don’t experience impact or significant temperature changes.

Two different structural adhesives will most liekly match your current needs – ASI – MP 55420SC Methacrylate Structural Adhesive and ASI – MP 55320 Methacrylate Structural Adhesive.

ASI – MP 55420SC Methacrylate Structural Adhesive

The ASI – MP 55420SC Methacrylate Structural Adhesive is a two-part adhesive that bonds everything from plastics to metals to composites. While the bonded area is durable, as well as impact and temperature resistant, it will also be flexible.

This structural adhesive has an off-white color when applied, and once it cures, it has a shear and tensile strength of more than 2,500 PSI. It is best to use this product in temperatures that range between sixty-five and eighty degrees Fahrenheit, but once cured, it can withstand temperatures from sixty-seven degrees below zero up to two hundred and fifty degrees.

The ASI – MP 55420SC is easy to apply, cures at room temperature, and there is no surface prep needed before applying it. This product can also be stored for up to one year after it ships, as long as it is not stored in temperatures lower than fifty-five degrees or higher than seventy-five degrees.

This structural adhesive is flammable, so care should be used to ensure to keep it away from heat and open flames. If any of this material spills, it should be cleaned up using a product that contains either N-methyl pyrrolidone or citrus terpene, before it has a chance to cure.

ASI – MP 55320 Methacrylate Structural Adhesive

The ASI – MP 55320 Methacrylate Structural Adhesive is another two-part adhesive that bonds to almost any type of material together. It has the same qualities and warnings as the structural adhesive mentioned above.

The one major difference is that the work time for this product is eight to twelve minutes, with a fixture time of twenty-five to thirty minutes. The product mentioned above has a work time of four to six minutes, with a fixture time of twelve to eighteen minutes. While the time you spend using this structural adhesive is longer, you will see a slightly higher shear strength rate when you are finished.

It is crucial while using either one of these structural adhesives that you are extremely careful to not get any of it in your eyes, on your skin, or in your mouth. If you do, you must go to the nearest emergency room immediately for treatment.

Choosing the correct structural adhesive is very important because not all of them will do what you need. Some are better with certain materials than others, while a few are better when it comes to flexibility, impact resistance, and temperature resistance. Therefore, ask the questions above before you even consider which structural adhesive to use on your next project.

Table Saw Lubricant

Best Table Saw Lubricant

Table saws are amazing tools that can help you construct almost anything, but only if they are working correctly. If you are noticing that your table saw isn’t performing the way that it used to, you may be dealing with a blade that has a buildup on it. When working with blades in that capacity, you’ll find that your cuts are not as precise and that materials can be damaged much easier.

Thankfully, there are a couple of different types of table saw lubricants that can reverse that and bring back the performance of your table or circular saw. Let’s take a look at a couple of our favorites:

Bostik BladeCote

Bostik BladeCote is a lubricant for table saws that will reduce not only the friction that you may be experiencing but also prevent a buildup of both pitch and resin. It is quite easy to use this lubricant. All you need to do is spray a thin coat onto the blade and let it dry for a few seconds. It is usually best to repeat this process after a few cuts, to ensure that the entire blade is covered. After that, daily use is recommended unless your workload is heavy, or you are using a material that is more difficult to cut. In those scenarios, you may need to apply this product more often.

Some reasons we prefer Bostick BladeCote:
• Reduces the heat from the blade, up to thirty percent, as well as friction when cuts are being made
• Your saw blade will have a longer life expectancy, up to three times the average
• A resin will build up less frequently
• This product is not made with any silicone or petroleum oil
• There is no saw drag when this lubricant is used regularly
• The lubricant will not become gummy over time, even after you have applied several coats
• This lubricant will not stain wood, nor will it interfere with any other finishes or glue that is used
• Will work on all types of blades including carbide stellite, steel, and diamond tipped

Bostik GlideCote

Bostik GlideCote is another table saw lubricant that assists with the regular maintenance. Once this lubricant is applied, you will see a significant drop in the friction of all metal, plastic, and laminate materials. A quick application will have you using your table saw without issues, and you can keep it that way by reapplying the GlideCote at regular intervals.

There are a few benefits to using this lubricant for table saws, and they include:
• Prevents hang-ups from occurring on the sliding surface of your table saw
• This product does not contain any petroleum oils or silicone
• This lubricant is thirty percent more slippery than paste wax, ensuring a better slide
• Easier to apply than paste wax and a much faster application too
• This lubricant last three times longer than paste wax every time it is applied
• After numerous applications, you will still not see a buildup of this lubricant
• Wooden finishes can never be damaged, and other materials will not stain from use of this lubricant

Both these Botsik lubricants have been designed to have your table saw working smoothly. Contact us for more information about your adhesive or lubrication needs.
