So, you’ve just poured a large mold, and you’re noticing bubbles forming.

This can be due to several reasons, with the biggest one being moisture or trapped air.

Bubbles may form because you’re working:
1. In an environment that’s too humid
2. With wet molding surfaces or porous stone masters that weren’t properly sealed
3. With wet mixing equipment or your mixing technique is whipping the material too much
4. With too much mold release

If you’re unfamiliar with , you may not know all the applications it can be used for, including:

- Mining and excavation projects
- Work and utility vehicles
- Commercial flooring

If you’re working with a brushable hard coat for the first time to protect your EPS and fabrications, there are a few things you must know for successful application.

1. Make sure to apply it to the recommended thickness listed on the technical data sheet (TDS).

2. Make sure to follow the mix ratio listed on the TDS.

3. Make sure to thoroughly mix the components together.

4. Make sure you’re working in a temperature-controlled environment with low humidity.

Did you know pourable thermoset urethanes are compatible with 3D printing materials like PLA?

In this new video from VFI, we take you through the full process of 3D printing a mold and then casting one of our 90 A fast-setting elastomers to make chess set pieces.

Urethane casting elastomers like this one are typically best used in an injection molding system, but due to the size of the parts, we were able to pour them by hand before they cured.

If you’re interested in a material like this or want to familiarize yourself with other 3D-printing compatible materials from VFI, please reach out through the website or by calling (800) 307-9218.
