Moreover, the quality of tube-type products is generally not very good. Most companies will not use tube-type packaging for 750ML and high-quality products, because the foam rubber of tube-type products is smaller than The pressure of the gun type is small, and sometimes it cannot be driven clean, and it is easy to cause problems such as the valve not being able to be driven out. In addition, the foam cells produced by the tubular foam glue are not as delicate as those of the gun type, and the expansion force is relatively large. The cost of the gun type is actually lower than that of the tube type.

B. When replacing the material tank, shake the new tank well (at least 30 times) and remove the empty tank , quickly replace the new material tank to prevent the spray gun connection port from solidifying.

C. The flow control valve and trigger of the spray gun can control the size of the foam flow. Immediately after the glue application is completed Clean the spray gun with cleaning agent, then close the flow valve clockwise.
