Common issues

Squeeze bottle Manual squeeze gun

Manual applicators such as bottles and squeeze guns are often used for adhesives, sealants, and similar thick fluids. Although inexpensive, these devices can be time-consuming, plus can create strain on the hand with frequent use.

Mix two-part adhesive Apply

Two-part adhesives are especially cumbersome. Many facilities still mix by hand on a plate and apply by daubing with a thin stick. This method is particularly slow, often requires continuous pinching motions, and is prone to defects because of poor mixing and misapplied material.

Common options for improvement

Dispenser applicator Foot pedal control

Generally, the best approach is to use dispensing systems, which can deliver the material quickly, precisely, and with minimal effort.

Dispenser tube and flexible holder

A particular advantage of dispensing systems is that the applicator can be attached to a holder that positions the tip adjacent to the point of use.

Two-part mixer/dispenser

Dispensers for two-part materials are more complex pieces of equipment, but provide similar benefits for improved production and less hand strain. Depending upon the material and application, the mixing systems are either combined with the dispensers of available as separate units. In either case, mechanical mixers generally provide a more throughout mix than humans are capable of.

A large number of vendors can be found on-line.
