Hot glue is also known as a hot-melt glue and is a special type of adhesive that is sold in the form of cylindrical sticks that can be applied with a hot glue gun. Now the major question Is hot glue water resistant?
The glue gun has an inbuilt heating element that melts the cylindrical plastics converting them into liquid glue which can be pushed out using finger pressure or a mechanical mechanism.
Is Hot Glue Water Resistant? Proven!
Once the glue comes out of the nozzle, it solidifies after several seconds to form a tight bond between surfaces. Is hot glue water resistant?
The answer is YES.
Hot glue is water-resistant, and the points below expound in details why hot glue is waterproof.
Types of Hot Glue Adhesives
Hot glue is made using polymer compounds which are not water-soluble. The characteristics of the glue vary depending on the polymer compound that has been used to make the oil.
The following polymers/compounds are used to make hot glue:
1. Polyamides
Polyamides are polymer compounds that are used to make hot-melt glues. Polyamides are used to bind porous surfaces strongly. A striking advantage of these thermoplastics is that they possess excellent characteristics that make them suitable for high strength applications.
The polymers are chemically stable, making them a suitable choice for binding surfaces in rough environments. Polyamides are waterproof, and this means that hot glues made using polyamides will be water-resistant too.
2. EVA (Ethylene Vinyl Acetate)
Ethylene Vinyl Acetate is an effective hot glue adhesive that is popularly used to bond paper products. The compound is water-resistant and sets quickly after application.
The hot adhesive takes approximately 10 seconds to form a strong bond between the bonded surfaces. To achieve a perfect bond, Ethylene Vinyl Acetate is usually mixed with additives such as resin and wax.
The compound is also popularly known for its outstanding characteristics which make it suitable for waterproofing and conditioning leather.
3. Polyethylene
Polyethylene is another compound that is used to manufacture hot-melt adhesives. The polymer has excellent chemical characteristics that make it a suitable choice for making hot glue. The compound is water-resistant, making all its glue products waterproof.
Hot polyethylene glue is mainly used to seal trays and cartons. Also, polyethylene glue has exceptional thermal stability.
4. Amorphous Poly Alpha Olefins
They are also known as APAO adhesives have long set times and are suitable for applications that have long exposure times. The glues are waterproof and have soft textures which make them ideal for use in product assemblies.
Amorphous Poly Alpha Olefins are usually combined with synthetic resins to enhance their adhesion characteristics.
In addition, APAO adhesives are utilized in paper packaging industries and in diaper-making companies.
5, Metallocene
Metallocene adhesives possess excellent thermal properties like polyethylene adhesives. They are lightly-colored and are mainly used to seal cartons and trays.
In addition, Metallocene has exceptional char-free capabilities that help in minimizing maintenance exercises on machines that break down frequently because of unwanted accumulations of carbon.
This is the most well-known specialty hot glue for permeable lightweight materials, for example, paper, cardboard, fabric, and children’s artworks.
Water is the transporter; this implies simple tidy up and low poisonous quality. Remember that the paste must dry before quality is noteworthy and the task regularly requires clipping to hold it set up until the glue is totally set and dry.
This likewise implies white specialty paste ought not to be utilized in applications that require water obstruction.
White specialty glue dries clear and is to some degree adaptable. Get innovative and include fillers, similar to fine sparkle, shade, or water-based sustenance shading for beautifying impacts.
Final Verdict
To summarize, it is apparent that all the above compounds that are used to manufacture hot melt adhesives are water-resistant. Therefore, the answer to ‘Is hot glue water-resistant?’ is YES.
