Compact, lightweight handguns offer a wide range of pattern capabilities and durable design for manually operated adhesive and sealant applications. Nordson® Series AD-31 handguns combine efficient design and reliable performance for manually dispensing hot melt adhesives, sealants and other thermoplastic materials. The wide selection of models satisfies a full range of applications, including packaging, assembly and sealing operations. The series consists of various models for producing solid or foamed extrusion beads, spray patterns and swirl spray. For handling high-viscosity or filled materials, AD-31 LBS Extrusion handguns incorporate a large ball-and-seat and larger flow paths. Designed with the operator in mind, lightweight AD-31 Extrusion and Swirl handguns weigh less than two pounds. A distinctive “ever-cool” handle contains no heated components or adhesive-flow paths that could cause discomfort to the operator. Heated gun components are totally enclosed within the exterior gun shell, helping to reduce the risk of burns. Capable of standing up to the most demanding applications, AD-31 handguns feature an impact-resistant molded shell for extended service life. To eliminate hose twisting, AD-31 Extrusion and Swirl models feature a 360-degree swivel connector. A broad product range allows compatibility with most Nordson applicators and drum melters. Selection depends on the applicator specified, as well as pattern desired, material viscosity and output rate requirements. Depending on the applicator design, handguns employ either an RTD sensor (resistance temperature detector) or a preset thermostatic temperature sensor. RTD sensing reduces temperature fluctuations that could negatively affect flow and cause adhesive char formation. A wide operating temperature range of 130° to 450°F (55° to 230°C) provides additional application versatility.

Nordson Series AD-31 Handguns Extended nozzles used with AD-31 Extrusion handguns allow easy access and deposition control into tight areas. The ergonomically designed Series FP-200 Gun helps minimize physical stress and fatigue and provides dependable performance and application flexibility. The lower heat density of AD-31SW swirlspray patterns minimizes thermal distortion on heat-sensitive substrates. Ⅲ Compact, lightweight design ensures handling ease. Ⅲ “Ever-cool” handle provides comfortable operation and helps reduce risk of burns by containing heated components and adhesive-flow paths...
