The advantages of hot melt adhesives are mainly manifested within the following facets:

 

 

1 Fast curing speed, good bonding power and flexibility.

 

 

 

 

Hot melt adhesives can remedy and bond within just a few tenths of a second to a few seconds, and have the traits of melting when heated, and bonding when cold. This enables packers to use hot melt adhesives to make use of higher-speed production lines, and enhance production while reducing faulty products, which is handy for steady and automatic high-speed operations, and has a lower cost.

 

 

 

 

2 The ability of hot melt adhesive is stable

 

 

It isn't affected by changes in temperature and humidity from morning to nighttime in the working environment, which ensures the bonding fastness and eliminates the inherent adhesive peeling problem of packaging machinery.

 

 

 

 

3 Hot melt glue does not include water and another fluxes

 

 

Its solids may be made into blocks, films, strips or pellets, which are straightforward to transport and store. It has a long service life, eliminates damage and waste, and is easy to use.

 

 

 

 

four The hot melt adhesive doesn't include solvents and doesn't emit harmful and toxic fumes, is just not easy to burn or explode, is safe, and will not cause secondary pollution to the environment and endanger human health.

 

 

 

 

5 The hot melt adhesive forms a glue layer that is immune to water and moisture, and may form a reliable glue even in a damp environment.

 

 

 

 

6 Hot melt adhesive could be repeatedly melted and bonded

 

 

If the hot melt adhesive coated on the adherend can't be bonded due to cooling and solidification, it may be reheated for bonding operation, so it is very suitable for bonding with some particular process requirements components, such as the restoration of some cultural relics.

 

 

 

 

7 A wide range of bonding objects, each bonding and sealing, no drying process, simple bonding process, and good financial benefits.

 

 

 

 

8 Good gloss and gloss retention, wonderful shielding.

 

 

 

 

Of course, hot melt adhesives even have some disadvantages, as described beneath:

 

 

1 There are limitations in performance, inadequate heat resistance, limited bonding strength, and poor chemical resistance. Modification of the hot-melt adhesive base polymer can improve the heat resistance and strength of the hot-melt adhesive.

 

 

 

 

2 Coating by hand, the impact will not be good, and the waste of rubber is troublesome to control. Subsequently, it is important to be geared up with special equipment to melt and apply glue, corresponding to a hot melt gun, which is inconvenient to make use of and restricts its use and promotion.

 

 

 

 

3 Bonding is typically affected by climate and seasons. Usually, the wettability is poor in winter, the curing turns into slower in summer season, and the melting time is shortened when the wind is strong.
