This article will answer the following question: “Is gorilla construction adhesive flammable?”. We will discuss rather the gorilla construction adhesives are flammable or not, and also present all safety data relevant to the topic.
Is gorilla construction adhesive flammable?
No. Gorilla construction adhesives are not flammable. According to the safety data made available by The Gorilla Glue Company, none of the three versions (max strength clear, heavy duty and heavy duty ultimate) of Gorilla construction adhesives are flammable.
What is construction adhesive?
In the construction industry and services, adhesives are materials that can bind materials together. They can glue the surfaces of different or equal materials, allowing load stress to be distributed more equally in a joint.
Adhesives must have some flexibility but also high cohesive strength, allowing the materials to have both stress absorption capabilities and strong bonds. This is the main reason why polymers are used to this end.
They can be made out of natural or synthetic compounds. In general, an adhesive is a polymer (a kind of plastic).
Adhesives can be classified by many methods such as dispensing method, application, and primary resin. It all depends on the manufacturer and the given application.
There are many kinds of adhesives because adhesion happens differently on every kind of surface. Each surface has specific chemistry that will dictate how the glue will work.
Some adhesives are made specifically for some kinds of tasks and surfaces, but there are also those meant for many purposes.
Strong adhesives are the ones in which the adhesion happens when the polymer reacts with the given surface. New chemical bondings are created between the glue and the materials.
Adhesive bonding effects
When gluing two materials together, two things that require attention are stress distribution and load leveling.
Adhesives are capable of binding a larger area when compared to other assembly techniques, which facilitates a more evenly distribution of weight.
When working with nails, for example, all the structure’s weight is distributed in a little surface area, which can enhance fatigue. Using adhesives can be much stronger.
The unique and wide possibilities of applying adhesives from several different chemical properties also allow to bond surfaces from different materials, which is a very important asset in construction.
What is a polymer?
Anything that can be put on a kitchen scale and weighted has mass. If it has mass, it also has atoms. When at least two atoms bond together they can create a molecule.
A very important kind of molecule is called hydrocarbon. They are basically made of one part of Carbon and two of Hydrogen, more or less (in atom quantity, not mass).
They can have millions of arrangements and compose nearly all that we call life.
A specific kind of organic compound is called polymers. They are macromolecules that consist of smaller structures that repeat themselves, like a centipede. Such chemical species can often have a neutral to high flammability.
It’s better to use Gorilla Construction adhesives above 40ºF, but the application temperature is between -40ºF and 200°F, for all labels.
The surface where gorilla glue will be applied must be clean and free of debris, grease, and, oils. But it does work if there’s a little moisture on.
The product must be stored in a cool, dry location, with the nozzle attached and filled with adhesive.
To remove the adhesive from a spilled surface that’s still wet, wiping it using a piece of cloth will do the trick, and using a solvent like isopropyl alcohol, following the manufacturer’s instructions accordingly.
If it’s already cured, mechanical means may be required as well.
Personal protection equipment is also indicated by the fabricant when dealing with these adhesives. Although, if it got on your skin you may wash it using soap and warm water normally.
The Gorilla Glue Company provides a phone line to speak with a medical professional in cases of bonded skin. If you are in the U.S, the number is 1-800-420-7186.
Gorilla heavy duty construction adhesive
According to the manufacturer, this product is regarded as good for all surfaces and is all-purpose. This adhesive is considered all-weather, it’s tough and versatile.
Although, it’s not recommended for polyethylene, polypropylene, bitumen, and similar materials.
The product can be applied both indoors and outdoors, it holds in 30 seconds, can fill gaps, has high strength, is durable, and can be painted over.
Ingredients (in mass percentage, w/w)
Most of the ingredients are inorganic and nonflammable.
- Limestone 30-6%
- Carbonic acid, calcium salt (1:1) 10-30%
- Stearic Acid 1-5%
- Quartz 0.1-1%
Carbonic acid is not organic and also doesn’t present flammability. Stearic Acid is organic, but it’s a polymer with a long carbon chain that can barely catch fire. The other two ingredients do not catch fire.
The health hazards of this product are considered a warning.
This product may cause skin allergies. If it causes further irritation, medical advice or attention is required. Vapors from this product should not be inhaled in any circumstance.
Quartz alone is a cause of cancer of the respiratory tract and lung disease in workers that inhaled it chronically, but the quartz from the glue formulation is mixed with the paste, so it’s not inhalable. This hazard is not present in this product.
The product possesses a considerably low flashpoint (around 93.3°C// 200 °F). Also, only 2% of the product is made of volatile organic compounds, which are normally associated with flammability.
But in this case, since most of the ingredients of the material are not combustible, having a low flashpoint doesn’t change much. The organic part of this Gorilla glue can still burn, but it’s not likely to happen and wouldn’t have much fuel to be burned.
Upon curing, small amounts of methanol can be released due to hydrolysis reaction, which is common in certain kinds of adhesives. After the cure, the product should be safe against fire hazards.
Gorilla max strength construction adhesive clear
The manufacturer implies that this adhesive is the strongest among its labels. Also claims that the product is versatile and easy to use. It can be painted over.
The company also indicates that the Gorilla max strength allows repositioning of the material if the product is still wet, says that the product works underwater, is very durable during all weathers, dries easily, fills small gaps, and is twice strong as other similar labels.
This product has only two main ingredients: a polymer and a mixture of additives.
The first one is a molecule that has a long name (N-[3-(Trimethoxysilyl)propyl]-1,2-ethanediamine), you can check it online searching by its CAS nº: 1760-24-3.
The additives are a trade secret, so they couldn’t be found.
The product can cause similar problems as the previous one.
It may cause allergies and be irritant to the skin. The product could unleash toxic vapors.
The product can cause severe eye damage and be harmful to aquatic life.
If gets in contact with the skin the product can be washed with warm water and soap.
No flammability is expected according to the fabricant.
Specific information about the polymer of this product also revealed that no combustion is expected, under usual circumstances.
Small amounts of methanol can be released during the cure due to hydrolysis reaction, which is common in certain kinds of adhesives. After the cure, the product should be safe against fire hazards.
Gorilla heavy duty construction adhesive ultimate
This label is considered the most durable among the others.
Just like the previous ones, the fabricant alleges that this product is tough, versatile, waterproof, paintable and easy to dispense.
The product can also fill gaps and is shrink proof.
Gorilla heavy duty ultimate holds immediately for an instant grab and can hold several kinds of surfaces.
It has only two ingredients: Vinyltrimethoxysilane and Titanium oxide.
The first one is a silicone polymer. The other is a known additive.
This product may cause damage to organs through prolonged exposure. The use of gloves is really important for workers that use Gorilla heavy duty ultimate, but it’s essential for any of the labels.
The product doesn’t present any relevant flammability.
While curing, the product may unleash methanol as a result of the chemical adherence to the surface. Methanol is flammable, but only a bit is produced.
Gorilla construction adhesives are not flammable. While the adhesive is being cured, a few methane molecules may form when the polymer adheres to the surface. Even though this molecule is flammable, only traces of it are produced so it’s not a fire hazard.
If there’s no source of ignition (flames, intense heat, sparks, lit cigarette, etc), Gorilla Construction adhesives won’t ignite.
