Advantages and disadvantages of water-based adhesives, solvent-based adhesives, and hot melt adhesives

Advantages and disadvantages of water-based, solvent-based and hot melt adhesives: Benefits and drawbacks of water- based, solvent- based and hot dissolve adhesives:

advantage:

Water- centered adhesives: low cost, non-- flammable, non- toxic solvent, wide selection of solid content, wide viscosity range, high concentration of large molecular weight materials, adjustable permeability and wettability

Solvent- centered adhesives: Water proof, drying price and wide open time, large initial tack strength or amount of time readers stay, simple to wet some hard- to- stick areas

Hot Melt Adhesive: Packing and freight cost per unit materials is low, no freezing, simply no drying and drying equipment, easy to bond impermeable surface, rapid cement adhesive strength, good storage stability, constant film, water resistance, no Throughout the water vapor.

Disadvantages:

Drinking water- based adhesives: poor drinking water resistance, freezing, fabric shrinkage, wrinkling or curling from the paper, contaminants of certain metalware, corrosion in certain metals, slow drying, negative electrical properties.

Solvent- centered adhesives: Inflammable and explosive, dangerous to health, require special surge- proof and ventilation gear.

Hot melt adhesive: It requirements special application equipment, viscosity and temperature limit make the power limited, it will decompose below continuous heating, and the control of glue amount is awful, and it may have to preset the the adherend.
