The world of adhesives is rich and colorful, all types of adhesives can really make people have a dazzling feeling, not to mention the differences between these adhesives, but industry personnel may not all be able to say clearly. Today we want to tell you the difference between hot melt adhesive and water based adhesive!
1-The external difference
Hot melt adhesive: 100% thermoplastic solid
Water based adhesive: take water as a carrier
2-Coating way difference:
Hot melt adhesive: It is sprayed in a molten state after heating, and solidified and bonded after cooling.
Water based adhesive: The coating way is to dissolve in water and then spray. The production line of the coating machine requires a long oven, which occupies a large area and is complicated.
3-The advantages and the disadvantages of hot melt adhesive and water based adhesive
The advantages of hot melt adhesive: Fast bonding speed (it only takes tens of seconds or even a few seconds from applying glue to cooling and sticking), strong viscosity, good water resistance, good caulking effect, low permeability, good barrier properties, solid state, easy to access , Stable performance, easy to store and transport.
Environmental protection: Hot melt adhesive will not harm the human body even if it is in contact for a long time. It is green and environmentally friendly and reproducible, and meets the requirements of international environmental protection agencies. This is an unparalleled superiority of other adhesives.
The advantages of water based adhesive: It has a small odor, is non-flammable and easy to clean.
The disadvantages of water based adhesive: Various additives are added to the water based adhesive, which will cause certain pollution to the environment. In addition, the water based adhesive has a long curing time, poor initial viscosity, poor water resistance, and poor frost resistance. It must be stirred before application to maintain uniformity. The storage, use, and bonding environment temperature of the water glue is required to be 10-35 degrees.
The above is about hot melt adhesive and water based adhesive related knowledge, NDC focus on hot melt adhesive coating professional, in the future we will continue to expand our business scope, strive for a higher level.
