Does the pressure-sensitive adhesive lose its viscosity after curing
29 Sep 2019
Pressure sensitive adhesive after curing there is no viscosity, will it lose viscosity or adhesive strength reduced?
Characteristics of pressure-sensitive adhesive:
Pressure-sensitive adhesive referred to as pressure-sensitive adhesive, according to the performance form can be divided into solvent type, milk wave type and hot melt type three, belongs to the reaction type
Adhesive, no solvent, no pollution, more convenient to use.
As a result of the pressure sensitive adhesive easy to use, opened after the general
It is widely used in the manufacture of pressure-sensitive tape, adhesive sheet and pressure-sensitive label.
Curing of pressure-sensitive adhesive:
After the initial curing of the pressure-sensitive adhesive, the adhesive layer will have a certain bonding strength, and in the future for a long time to bond
The intensity will continue to rise.
Therefore, after curing, increasing curing time or enhancing curing temperature can enhance bonding
Intensity is very beneficial.
For some specific rubber, curing temperature can not be casually lowered, the temperature will make the pressure-sensitive adhesive curing is not complete
It leads to the decrease of bonding strength, which is very difficult to make up for.
So the pressure-sensitive adhesive in curing not only will not lose viscosity, but in the condition of good curing temperature control, with
Pressure - sensitive adhesive curing time to improve the bonding strength will be further enhanced.
