High vs Ultra-High Viscosity Resins: Key Differences Explained

Q: What Sets Viscosities Apart?

High viscosity epoxy resins are formulated to retain some flow and possess self-levelling properties. They are ideal for artists who need a balance—enough thickness to control colour blending, but with sufficient movement to smooth out medium-thick layers for coasters, trays, and general surface art. Ultra-high viscosity resins , such as Art Pro Deluxe , remain almost completely stationary upon application. This means you can create crisp, defined lines and patterns with minimal colour spread—perfect for geode-inspired designs, ocean wave details, and vertical work where resin needs to stay put until cured.

Difference Between High and Ultra-High Viscosity Resins

Choosing the right epoxy resin viscosity is crucial for achieving your desired finish in art and craft projects. Below, we explore the key differences between high and ultra-high viscosity resins to guide your selection.

What Sets Viscosities Apart?

High viscosity epoxy resins are formulated to retain some flow and possess self-levelling properties. They are ideal for artists who need a balance—enough thickness to control colour blending, but with sufficient movement to smooth out medium-thick layers for coasters, trays, and general surface art.

Ultra-high viscosity resins, such as Art Pro Deluxe, remain almost completely stationary upon application. This means you can create crisp, defined lines and patterns with minimal colour spread—perfect for geode-inspired designs, ocean wave details, and vertical work where resin needs to stay put until cured.

Selecting the Right Resin for Your Technique

For fine line work, detailed art, and projects where precise control is required, opt for an ultra-high viscosity product. Art Pro Deluxe is formulated especially for this need, offering sharp line separation and reduced colour bleeding.
If your project involves filling larger areas, producing glossy surface coats, or you still want some self-levelling effect, a high viscosity resin such as Art Pro will offer the balance you need.
General crafting or jewellery projects might be better served with a medium viscosity option like One-2-One, which offers easier mixing and some customisation of thickness through additives.

When This Matters Most

The choice between high and ultra-high viscosity resins becomes especially important when your artwork relies on defined boundaries or you’re working on three-dimensional or vertical surfaces. Ultra-high viscosity resins let you paint or pour on edges or upright panels without the worry of drips or unwanted blending, ensuring your design stays exactly as planned.
