Key Features of an Epoxy Rollcoat
I was recently asked to elaborate on some of the key features I look for in a dedicated epoxy rollcoat.
I was recently asked to elaborate on some of the key features I look for in a
dedicated epoxy rollcoat.
In the video below I did just that, including the demonstration of a feature I can best describe as "variable viscosity". The formulating philosophy behind variable viscosity is to create a product that has low viscosity when getting the product out on the floor, but then increases in viscosity when you stop moving so it can hold its shape.
This feature is of great importance when it comes to sag resistance (e.g. applying onto a cove), but I have also proven the benefits when it comes to issues like colour separation or shadowing under epoxy flake flooring when applied direct to concrete.
It also results in a slightly rippled texture, which provides a more forgiving finish when used as a final coat in warehouse type
applications.
Video Transcription:
I'm out here in the lab today and I'm having a bit of a play and I realised that I'd spoken about a rollcoat product a while ago, and I was trying to describe its properties, and it's a little bit hard to explain without showing you.
While I was out here in the lab, I thought I'd actually open up one of these kits and explain to you how this rollcoat behaves, why it was formulated this way, and what that means for installers in the field.
And then we'll see why it makes sense having a dedicated roll coat.
Here I have the Part A bucket of the product, and it's probably easiest to show you what I call variable viscosity by showing you in the untinted Part A.
You can see that I stick the tongue depressor in it and it looks like a very thick product. But if you start to agitate it, you see that it drops its viscosity.
And if you agitate it even more, like if I was drill mixing it, the viscosity would drop right down.
The formulation principle there that I came up with all those years ago was I wanted something that was solventless, that I could squeegee out and wet back roll easily.
And then after I've finished with it, it wouldn't settle out, it wouldn't continue to flow. It would actually tend to hold its body and hold its shape.
Now, that's important if you are doing verticals, certainly because then it's got anti-sag properties. But I also find with rollcoats, it's important on how it behaves horizontally. And that's to stop the colour separation issues that often happens when it comes to rollcoats that are low viscosity and don't have enough body in them.
That was the formulation principles, and so you might understand now when I talk about a dedicated formulated rollcoat, that they're the properties that I'm looking for.
I hope that makes sense. If you have any questions, of course, then just ask.
And as always, I'm Resin Jack. Take care and keep smiling.
