Viscosity describes a liquid's degree of resistance to flow. Within the context of epoxy resin, formulas, the viscosity determines if the material will drip or spread evenly and if it should be poured, dipped, or painted on the material. Viscosity also affects how much of the epoxy perforates the substrate and which physical properties are produced.

1.Low Viscosity

Low-viscosity epoxy resin is thin and works well for deep level penetration and filling small cavities.

The consistency helps prevent air bubbles, which facilitates bonding between the epoxy and substrate. You can use low-viscosity epoxy resin for encapsulation, sealing, and potting.

2.Medium Viscosity

Medium viscosity epoxy is thick. It' s less permeable than low-viscosity formulas and offers greater mechanical strength. The material can withstand moderately high temperatures and is often used for filament winding, vacuum bagging, and tooling.

3.High Viscosity Epoxy

High-viscosity epoxy has a paste like consistency and is the most resilient option. It offers superior adhesion and shock and heat-resistance. Technicians use this formula for projects that demand exceptional durability and strength.
