| How are Hot Melts Applied? |
|
|
|
Hot melt adhesives are thermoplastics, which become liquid between temperatures of 80 – 220 °C and solidify again by cooling down. They are applied in liquid state without using water or solvents. Exact dosage and amount of Hot melts can be controlled by using a Despensing System. There are various types of Despensing System, in general it has a pre-melter with pump, a Temperature controlled Hose and an Application Unit. There are innumerable types of application Units available in the market. Some basic types are as follows : |

It involves a pattern roller dipped in a bath of hot adhesive and transferred directly to the material or to a release liner which will be laminated to the material. Metering blades are used on the pattern roller and the material to control the thickness and the smoothness of the coating. This process is good for laying down thick coatings on porous materials and for high volume patterns in line with other narrow web converting processes. We currently have 10" capacity for roll coating. |

It involves extruding the adhesive through a slot. This process permits controlled thickness of adhesive to be applied over wider widths at high speeds. The slot can be modified to lay down strips of material of any width desired in the web direction. The entire unit can be turned on and off rapidly to achieve patterns of rectangles with the adhesive |

Improves safety standards and reduces maintenance and energy costs without compromising on bond strength and These adhesives offer all the attributes of conventional Hot melt at lower application temperature (90 to 110 degrees c). |

|
It involves Squeezing the molten hotmelt through the pores of the screen on to the substrate. This can be done through machines or through manual methods. This is not a popular method of coating since the machines are not readily available and it is a little risky to coat liquid hot melt at 180 deg c. It is used for small scale production only |
