Acrylic adhesives are resistant to sunlight, not easily broken up by water/humidity, and can withstand temperature fluctuations. These features cause acrylic adhesives to be the most preferred type.
Strength Factors
Any acrylic adhesive’s strength depends on several highly critical factors and is measured in two ways:
Cohesion（the force causing molecules of the same substance to stick together ） and adhesion.
Cohesion is the measure of an adhesive’s ability to stick to itself, while adhesion is the measure of an adhesive’s ability to stick to another object.
Cohesion and adhesion are based on cure time, cure temperature, and viscosity.
Adhesion is slightly boosted during cure time and then settles into a permanent position.
Cure time refers to the amount of time the acrylic adhesive takes to mold into its position and harden into a proper glue. Cure time is inversely proportional to the cure temperature, which is the amount of heat used to cure the adhesive.
Viscosity refers to the adhesive’s resistance to flow.
Temporary acrylic adhesives are constructed with low cohesion, adhesion, and viscosity and can usually be broken up with water or low-grade adhesive removers without damaging the material they are applied to. Permanent acrylic adhesives have high cohesion, adhesion, and viscosity levels, and are made to resist virtually every kind of environmental condition.
