Enhanced Adhesion and Cohesion: Microcrystalline wax molecules contain a large number of branched alkanes and cycloalkanes. When melted, they exhibit good wetting properties on the substrate; upon cooling, they form a dense microcrystalline structure, significantly improving the adhesive’s initial tack and long-term adhesion.
Provides flexibility and crack resistance: Compared to the brittleness of paraffin wax, microcrystalline wax is soft and highly ductile, capable of absorbing stress and preventing the adhesive from cracking during bending or temperature changes, making it particularly suitable for applications subject to dynamic stress.
Regulates Rheology and Heat Resistance: As a thickener, it optimizes the adhesive’s viscosity and prevents sagging; its high melting point provides the adhesive with better dimensional stability and heat resistance at high temperatures.
