An adhesive, or glue, is a mixture in a liquid or semi-liquid state that adheres or bonds items together. Adhesives may come from either natural or synthetic sources. The types of materials that can be bonded are vast but they are especially useful for bonding thin materials. And we divide the common uses of adhesives into two broad categories.
Industrial and Commercial Use
Under this heading comes adhesive usage in all kinds of industries, small or heavy. Adhesives play an important character in processing to packaging, involved small industries like those of food products, toys or stationary items. Even the cling wrap around your phone card or the lipstick connected to its base has adhesives playing their roles. In heavy industries, adhesives play a central role, right from assembling spare parts of any machine, car paint or branding them with labels. In the construction industry too, for uniform distribution of stress, woods are bonded with strong adhesives. Apart from that, for painting and furnishing or home décor, adhesives are very essential.
Right from sticking envelopes to rejoining broken toys, we use adhesives very frequently. In form of glue sticks, cellotapes or gums, we use adhesives everyday to mend shoes, to glue postage stamps, repair something or attaching tags to gifts.
It is hard to say which is the most suitable solution when it comes to choosing the right types of adhesives. Different types of glues and adhesives work through different levels of adhesion or strength, so using one for a specific application may not work well with another. Here is a short list of some of the most common glues and adhesives in the market.
White glue is great for bonding paper products, such as cardboard, craft paper, art paper, handmade paper, and many others. Due to their ease of use and economical price, white glue is used for many paper-based projects, especially for children at school. One of the draw backs in using white glue is water solubility, which is not recommended for materials immersed in water. For water proof projects, you will need epoxy or a stronger type of adhesive.
Hot melt glue from glue gun
Hot melt glue is one of the most favorite types of glue by crafters. Often dispensed through a gun and used for a wider range of materials such as paper, fabric, and wood, hot melt glue provides better adhesion than common white glue. Unlike epoxy it doesn't have a long curing time. However hot melt glue is not ideal for outdoor applications or for projects that require water proofing.
Construction adhesive is a type of adhesive made specifically for construction materials such as wood, slate, marble, stone or for outdoor and indoor projects like flooring and paneling. Most types of construction adhesives are brilliant for outdoor installations because of the waterproof features.
Epoxy adhesive is another kind of waterproof adhesive that can bond porous materials. While epoxy glue takes some minutes to set and several hours to cure completely, it offers a stronger bond than white glue, super glue, and hot melt glue.
Choosing the right kind of glue depends on several factors; such as the materials you are using and the kind of adhesion strength you require. A good Hot Melt Adhesive can help you get your projects done on time, so take time to shop for the right glue or adhesive, according to the application you will be using them for.
