Different Density of Sealant
Different Density of Sealant
Density of adhesive is one of the important physical parameters. It represents the mass per unit volume of adhesive (usually measured in g/cm³ or kg/m³). Density not only affects the adhesion ability; but also determines the durability, overall weight. And the performance of the adhesive in each specific application.
Density is a measure of the mass of the adhesive per unit volume (g/cm³ or kg/m³). It helps determine the adhesive’s adhesion, durability, and load-bearing capacity. In other words, it tells you how thick or thin the adhesive is. The higher the density, the thicker the adhesive and usually has better adhesion.
High density : High density adhesives usually contain more solids. They have good tensile strength and can adhere firmly and permanently to difficult-to-stick surfaces such as metal, glass and ceramics. For example, high density adhesives are suitable for industrial and civil applications that require great durability.
Low density : Low density adhesives are suitable for light duty applications. Such as wood glues, paper glues and packaging products. Low density adhesives are usually easy to handle. But they may not be able to withstand pressure or high temperatures like higher density adhesives.
