The Adhesive that Mends Broken Mirrors: An Indispensable Magical Formula in Life featured-en

In our day-to-day existence, adhesives play an irreplaceable role, whether it’s in mending broken items or adding a splash of creativity to projects, their applications are as varied as they are extensive. This article delves into the scientific principles behind adhesives and how they have become an all-purpose aide in our lives.

The Working Principle of Adhesives

The efficacy of adhesives stems from their ability to initially be in liquid form, adhering quickly and then solidifying. These multifunctional adhesive substances, primarily polymers, can form a tight bond with target surfaces through chemical bonds and mechanical interlocking.

From paper and leather to plastics, adhesives simplify and strengthen the bonding of diverse materials.

From Liquid to Solid: The Transformation Process of Adhesives

The choice of a liquid form for adhesives is to exploit the molecular forces – like hydrogen bonds and Van der Waals forces – to fill the minute gaps on the surfaces of objects being bonded, thereby increasing the contact area and adhesive strength.

This fluidity allows the adhesive to penetrate into the tiny crevices of objects, providing a strong bond.

The adhesive process involves two steps, starting with the liquid wetting the object and seeping into its surface recesses. Once it solidifies, the glue and the object’s surface interlock, making it difficult for external forces to separate them.

The Curing Mechanisms of Adhesives

Adhesives cure through various mechanisms, including physical and chemical curing.

Hot melt adhesives become liquid at high temperatures and solidify upon cooling, becoming sticky substances; while others like white glues and transparent adhesives solidify through solvent evaporation. Cyanoacrylates (super glues) rapidly harden by reacting with moisture in the air.

Enhancing Adhesive Effect: The Power of Molecular Entanglement

Beyond transitioning from liquid to solid, some adhesives also enhance their bonding effect through molecular entanglement.

This entanglement ensures a more robust bond between objects, offering us more options to meet different bonding needs.

Super glues and the surfaces they bond do not entangle their molecules. When used, both surfaces must be coated with super glue. As they come into contact, the molecules begin to intertwine, resulting in a strong bond.

Pressure-Sensitive Adhesives: The Art of Flexible Choices

Most tapes on the market are pressure-sensitive adhesives, characterized by their easy-to-control stickiness and reusability, making them perfect for temporary repairs or attachments in everyday life.

The illustration above shows a transparent tape adhesive, with the glue evenly spread across the substrate; the illustration below is of a sticky note, where the glue is distributed in particles of varying sizes across the substrate, resulting in less adhesive per unit area.

UV Light-Cured Glue: The Frontier of Innovative Bonding Technology

Whether assembling metal figures for miniature models or bonding 3D printed resin parts, this product provides a sturdy and flexible bonding solution. The glue’s enhanced viscosity and ease of use make it an ideal choice for model enthusiasts during the processes of gap filling, shaping, and sanding.
