Weld On 16 Acrylic Perspex Glue

Weld-On 16 Acrylic Perspex Glue is a high-performance, solvent-based adhesive specifically formulated for bonding acrylic (Perspex® / PMMA) plastics. It is widely regarded as one of the most reliable and versatile acrylic cements available, making it the preferred choice for fabricators, sign makers, display manufacturers, and serious DIY users.

Unlike general-purpose glues, Weld-On 16 works by chemically softening the surface of acrylic materials and fusing them together to create a strong, permanent bond. Once cured, the joint effectively becomes part of the material itself, resulting in excellent structural strength and long-term durability. This makes it ideal for applications where appearance, strength, and precision are critical.

Weld-On 16 has a thick, syrup-like consistency, which allows it to fill small gaps and imperfections between mating surfaces. This makes it particularly useful where perfectly machined edges are not achievable or where minor tolerances exist. The thicker formulation also provides better control during application compared to thinner solvent cements, reducing the risk of runs and excessive capillary action.

This acrylic Perspex glue is suitable for bonding acrylic to acrylic, as well as acrylic to other compatible plastics such as styrene and butyrate. Common applications include display cases, signage, point-of-sale units, protective screens, model fabrication, light boxes, furniture components, and general plastic fabrication projects. It is equally effective for both clear and coloured acrylic sheets when applied correctly.

Weld-On 16 cures quickly, with an initial set time of only a few minutes under normal conditions, allowing projects to progress efficiently. Full bond strength develops over time as the solvent evaporates and the joint stabilises. Once cured, the bond is water-resistant and suitable for indoor and many outdoor applications when used with acrylic materials designed for external use.

For best results, surfaces should be clean, dry, and free from dust, grease, or protective films before application. Adequate ventilation is recommended, as with all solvent-based adhesives. Due to its professional-grade formulation, Weld-On 16 is trusted across the plastics industry for producing clean, strong, and visually seamless joints.
