Introduction to acrylic glue

Acrylic glue is a specialized adhesive designed to join pieces of acrylic, also known as plexiglass or methacrylate, ensuring a strong, transparent and long-lasting bond. This type of adhesive is essential in the manufacture, repair and assembly of products that use acrylic as the main material, due to the particular nature of this polymer and the need to preserve its aesthetics and physical properties.

There are different formulations of acrylic glues, adapted to various processes and technical requirements, ranging from liquid adhesives that dissolve the surface to create a molecular bond, to UV light curing glues or contact adhesives. Correct selection and application of glue is vital to ensure the structural and visual integrity of acrylic pieces.

Solvent adhesives

Solvent adhesives are probably the most commonly used for bonding acrylic pieces. These glues contain organic solvents that slightly dissolve the surfaces of the pieces to be joined, allowing the molecules to fuse and form a solid bond as the solvent evaporates. This mechanism creates a chemical weld that guarantees a strong and transparent joint.

This type of adhesive requires careful application to avoid bubbles or visible marks in the joint. It is common to find solvent adhesives in liquid presentations with fine applicators that allow precise control during use. Its drying time varies depending on the formulation, but is generally fast, facilitating efficient production processes.

However, it is important to consider that solvents can be toxic and require adequate ventilation during application, as well as the use of personal protective equipment to avoid health risks.

Ultraviolet (UV) Light Curing Adhesives

UV light curing adhesives represent an advanced technology for acrylic bonding. These liquid adhesives are applied between parts and remain liquid until exposed to a UV light source, which triggers a rapid polymerization process and creates a strong, transparent bond in a matter of seconds.
