High vs Low Viscosity UV Resin: Which One Should You Choose?
Not sure whether you need high or low viscosity UV resin?
Here is the easiest way to choose:
Choose High Viscosity UV Resin if you want a thicker resin with more control.
Choose Low Viscosity UV Resin if you want a thinner resin that flows more easily into small details and corners.
Both can be useful for UV resin crafts—the better choice depends on what you are making.
High Viscosity UV Resin: More Control

High Viscosity UV Resin is thicker and flows more slowly.
This makes it easier to control where the resin goes, especially when you do not want it to spread too quickly.
It is a good choice for:
- Doming
- Coating
- Sealing
- Projects where you want the resin to stay in place
- Creating a smooth finished surface
JDiction High Viscosity UV Resin has a viscosity of approximately 3700–3800 cps.
Its curing time is approximately 3–6 minutes, with 80D hardness and less than 3% shrinkage.
Simple way to remember it: thicker resin = more control.
Low Viscosity UV Resin: Easier Flow

Low Viscosity UV Resin is thinner and flows more quickly.
Because it moves more easily, it can reach small details, narrow areas and corners of a mold.
It is a good choice for:
- Intricate molds
- Irregular molds
- Small details
- Narrow corners
- Hard-to-reach areas
JDiction Low Viscosity UV Resin has a viscosity of approximately 1100–1300 cps.
Its curing time is approximately 2–5 minutes, with 80D hardness and less than 3% shrinkage.
Simple way to remember it: thinner resin = easier flow.
High vs Low Viscosity UV Resin at a Glance
| High Viscosity | Low Viscosity | |

Which One Should You Use for Your Project?
Still not sure? Think about what you are making.
Making a domed resin piece?
High Viscosity UV Resin gives you more control and stays in place more easily.
Coating or sealing a surface?
High Viscosity UV Resin is a good starting choice when you want a thicker, more controlled layer.
Filling a detailed mold?
Low Viscosity UV Resin can flow more easily into small features.
Working with an irregular mold or narrow corners?
Low Viscosity UV Resin is easier to move into hard-to-reach areas.
The Simple Choice
You do not need to overthink viscosity.
Choose High Viscosity UV Resin when you want:
More control + slower flow
Choose Low Viscosity UV Resin when you want:
Easier flow + better access to small details
The right formula simply depends on the project in front of you.
