Comparing Solvent-Based, Water-Based, and Solid Epoxy Resins

Epoxy resins are an integral part of floor construction for a wide range of industries. As the demand for versatile and durable materials continues to grow, the choice between solvent-based, water-based, and solid epoxy resins becomes a pivotal decision.

What are the advantages of Solvent-Based Epoxy Resins? 

Solvent-based epoxy resins are known for their strong adhesive properties and excellent chemical resistance. These resins contain solvents that evaporate during the curing process, leaving behind a hardened and robust surface.

Commonly used in industrial settings, solvent-based epoxy resins are favored for their favorable working time and ability to adhere to various surfaces.

Advantages of Solvent-Based Epoxy

- Superior adhesion to different surfaces

- Excellent chemical resistance


- Industrial flooring

- Automotive coatings

- Protective coatings for concrete and metal surfaces

What makes Water-Based Epoxy Resins unique?

Water-based epoxy resins have gained popularity as an eco-friendly alternative to solvent-based counterparts. These resins use water as a carrier instead of solvents, reducing volatile organic compound (VOC) emissions.

While water-based epoxy resins generally are not quite as durable compared to solvent-based options, they offer a safer and more environmentally conscious solution for various applications.

Advantages of Water-Based Epoxy

- Lower VOC emissions

- Safer for the environment and user

- Suitable for indoor applications


- Decorative floor coatings

- Art and craft projects

Why does Stonhard recommend Solid Epoxy Resins?

Solid epoxy resins, also known as high-solids epoxy, contain no solvents or water, offering a durable, high-performance solution. These resins typically result in a hard and impermeable surface.

Solid epoxy resins are valued for their strength and resistance to wear, making them ideal for demanding applications where durability is paramount.

Advantages of Solid Epoxy Resins

- High strength and durability

- Low VOC emissions

- Excellent resistance to chemicals and abrasion


- Industrial and commercial flooring

- Marine coatings

- Structural adhesives
