Palm trigger reduces operator fatigue in high-demand applications

The palm trigger design distributes dispensing effort across the palm rather than concentrating it on the index finger. This reduces repetitive strain during extended bonding sessions and improves operator comfort in production environments where the applicator is used continuously throughout a shift.

Quadrack feed system reduces downtime from reloading

Q-size adhesive sticks are 8 inches long, compared to the 2-inch sticks used in the standard TC applicator. The longer stick length reduces the frequency of reloading interruptions during continuous dispensing, helping to keep production moving with less manual intervention.

Lightweight construction for comfortable extended use

At only 10 oz, the applicator is designed to minimize arm and wrist fatigue during prolonged use. The glass-reinforced nylon body provides durability in industrial environments while keeping the tool light and manageable for operators throughout a full working shift.

Fixed operating temperature for consistent adhesive performance

The standard temperature version operates at a fixed 385°F (196°C), providing a consistent melt temperature matched to the performance requirements of compatible 3M Q-size hot melt adhesives. The low-temperature version operates at a fixed 265°F (129°C) for use with heat-sensitive substrates.

Positive check valve nozzle minimizes dripping between applications

The nozzle incorporates a positive check valve that helps prevent hot melt adhesive from dripping when the trigger is released. This reduces adhesive waste, keeps the work area cleaner, and minimizes the risk of adhesive contaminating parts or surfaces adjacent to the bond area.

Compatible with a wide range of 3M hot melt adhesive formulations

The Quadrack applicator is compatible with the full range of 3M Q-size hot melt adhesive sticks, including general-purpose, packaging, woodworking, and specialty formulations. This allows operators to switch adhesive types for different substrates or bond requirements without changing applicators.

Longer sticks mean fewer reloading interruptions per shift

Short TC sticks require frequent reloading, which interrupts workflow and slows throughput on busy production lines. The 8-inch Q-size sticks used with the Quadrack applicator allow significantly more adhesive to be dispensed before a reload is needed, reducing downtime and helping operators maintain a consistent work pace.

Palm trigger improves accuracy and reduces errors from hand fatigue

Operator fatigue from repetitive trigger actuation can lead to inconsistent bead placement and over-dispensing. The palm trigger reduces cumulative strain on the hand, helping operators maintain steady control and consistent adhesive placement throughout a full production shift.

Drip control keeps adhesive off parts and out of the waste stream

Uncontrolled dripping between dispense cycles wastes adhesive, contaminates work surfaces, and can damage heat-sensitive substrates. The positive check valve nozzle helps prevent unintended adhesive flow when the trigger is not engaged, keeping applications cleaner and reducing material waste.

TC Quadrack (Standard Temperature)

Fixed operating temperature of 385°F (196°C) for standard hot melt adhesives

The standard temperature variant is designed for use with 3M Q-size hot melt adhesive sticks that require a melt temperature of 385°F (196°C). It is the most widely used applicator in the 3M Hot Melt line and is suited to general-purpose bonding across a wide range of industrial substrates including wood, cardboard, foam, plastic, and metal. Output capacity is up to 3.5 lbs of adhesive per hour.

LT Quadrack (Low Temperature)

Fixed operating temperature of 265°F (129°C) for heat-sensitive substrates

The low-temperature variant operates at a fixed 265°F (129°C) and is designed for use with 3M low-melt Q-size adhesive sticks. It is suited to bonding heat-sensitive materials such as foam, thin plastics, and delicate packaging substrates where higher melt temperatures could cause surface damage or distortion. Output capacity is up to 2.6 lbs of adhesive per hour.

Q-Size Standard Temperature Sticks

For use with the TC Quadrack applicator at 385°F (196°C). Available formulations include general-purpose, woodworking, packaging, and multi-purpose adhesives for bonding wood, cardboard, foam, plastic, and metal substrates.

Examples: 3M™ Jet-Melt™ 3792 Q, 3M™ Jet-Melt™ 3792 TCQ

Q LT-Size Low Temperature Sticks

For use with the LT Quadrack applicator at 265°F (129°C). Formulations are designed for heat-sensitive substrates such as foam, thin plastics, and delicate packaging materials where standard-temperature adhesives could cause damage.

Examples: 3M™ Jet-Melt™ 3762 LM Q, 3M™ Jet-Melt™ 3748 LM Q

Safe Handling During Operation

• The nozzle and surrounding metal components reach temperatures exceeding 385°F (196°C) during operation. Do not touch the nozzle or heated components during or immediately after use.
• Always allow the applicator to cool fully before storing, handling for maintenance, or loading adhesive sticks.
• Keep the nozzle pointed away from people and flammable materials when the applicator is powered on.
• Do not leave a powered-on applicator unattended. Turn off the applicator when not in use for extended periods.
• For industrial and occupational use only. Not for consumer sale or use.

Maintenance and Storage

• Inspect the nozzle and body for adhesive buildup before each use. Excess cured adhesive on the nozzle can affect bead consistency and flow.
• Clean adhesive residue from the nozzle exterior using appropriate materials while the applicator is warm. Do not use sharp tools that could damage the nozzle or valve.
• Inspect the power cord before each use for signs of damage. Do not use the applicator if the cord is frayed or damaged.
• Store the applicator in a clean, dry location when not in use. Allow the applicator to cool fully before storage.
• Defective applicators can be returned to the 3M IATD Warranty Repair Center for a refurbished replacement. See 3M.com/refurb for details.
