A Helpful Guide to Processing High Viscosity Resins

High Viscosity Epoxy

There are many specialty resins that are formulated for highly-engineered applications, and because of their unique chemistries, they have a thicker viscosity than other products, making them a bit trickier to process. This article offers helpful advice to those who need to process a thicker viscosity resin in order to meet a wider range of requirements for their parts.

Vacuum Vs. Pressure When Resin Casting

vacuum vs pressure

Q. What is the difference between vacuum degassing and pressurizing? A. Vacuum de-gassing expands the air trapped during mixing or pouring, causing the bubbles to grow, rise to the surface, and in most cases, release. After a period of time the amount of trapped air decreases. The material’s viscosity and surface tension will determine how […]

Choosing The Best Static Mixer


“There are so many different static mixers, which one is right for my application?”, is a common question asked by our customers. The answer, as with many aspects to liquid molding, is complicated and should ultimately involve testing by the user within their application; however, there are some basic differences in the static mixer, which […]

3D Printing is Hitting the Mainstream


The world’s first 3D printed gun was successfully fired a few weeks ago and besides sparking numerous debates about gun laws and regulation of this technology, it also introduced 3D printing itself to mainstream America. In this article, I will discuss where this technology started, some of the current trends and the future possibilities for […]
