Where every job starts
Zinc Core 685
Zinc-rich epoxy primer — the first coat down on blast-cleaned steel. 8L Part A plus 2L Part B, one 10L kit.
The product
The zinc-rich primer.
A zinc-rich primer is the first coat onto abrasive-blasted structural steel, and it carries a high loading of metallic zinc. Zinc corrodes before steel does — so where the coating gets chipped on site, scratched in transit or cut through at a weld, the zinc around the damage gives itself up first and the steel underneath is left alone. That is what sacrificial protection means in practice: the primer is the coat doing the protecting, and anything applied over it is largely there to protect the primer.
It is supplied as two components you mix on site — Part A and Part B — because the two only have a working life together once they're combined.
Australian made, supplied direct. It comes from the plant to your workshop with nobody in between: no importer, no distributor, no extra layer sitting between you and the people who make it.
The kit
- Format Two-component
- Part A 8L
- Part B 2L
- One kit made up 10L
- Made in Australia
Substrate: abrasive-blasted structural steel. Mix ratio, film build and application detail sit on the technical data sheet — ask and we'll send it.
The system
Primer, build coat, topcoat — one supplier.
The range is built as a system — each coat formulated to sit on the one before it. All two-pack, all Australian made, all supplied direct.
Build coat
The barrier in the middle of the system — film build between the zinc and the weather.
Topcoat
Gloss and colour that hold outdoors, over the coats underneath doing the protecting.
Six products, one system.
Every product is a two-pack kit — Part A and Part B, Australian made, supplied direct. From the first coat down on blast-cleaned steel to the colour that faces the weather.
Zinc Core 685
Zinc-rich epoxy primer — the first coat down on blast-cleaned steel.
MIO Core 516
High-build MIO epoxy — the barrier coat in the middle of the system.
Thane Core 750
Two-pack polyurethane topcoat — gloss and colour that hold outdoors.
Epoxy Core 519
Surface-tolerant high-solids epoxy for less-than-perfect prep.
Fluor Core 890
Premium fluoropolymer topcoat for long-life, high-exposure assets.
Direct Core 570
One-coat direct-to-metal polyurethane for equipment and fast turnaround.
So here's how supply works.
Tell us what your spec calls for and what you coat in a month. You get your number on your volumes and a confirmed lead time on every coat — before you commit to anything. And whatever you're running today, we'll give you a straight read on it, including the coats we don't make.
Documents
Ask for the paperwork and you get the paperwork.
The usual way to get a datasheet is to ask a rep, who asks someone else, and it turns up when it turns up. Sometimes there's an account application in front of it — you have to become a customer before you're allowed to read what you'd be buying.
Not here. Email info@corecoatings.com.au or send the trade pricing form through, and the documents come back to you. No account application, no qualifying, no waiting on someone else's diary.
We don't publish them as downloads on the site yet — they go out on request, so ask and we'll send them.

The comparison
There isn't a major on the market whose products we don't know.
Two different things sit under that, and they're worth keeping apart. The read covers the whole market, every coat in the system. The written match covers the primer — the coat we make.
Send us the datasheet for anything you're using and we'll tell you what you've actually got
— what it's rated to, where it suits your steel and where it doesn't. Even if we don't supply the match.
That holds for every coat on your steel, including the build coat and the topcoat we don't make. You get the read regardless.
Tell us what you're on. We'll tell you what replaces it.
There isn't a protective coating on the Australian market we can't identify, break down and match against — same AS/NZS 2312 classification, same generic type, same zinc loading. Send us a product name or a datasheet and you'll get the comparison back in writing, before you order anything. Your spec doesn't change. Nothing gets re-qualified. The only thing that changes is who invoices you.
The product we supply against that comparison is the zinc-rich primer. It's the coat we make, and it's the coat the written match is for.
Send it to info@corecoatings.com.au — a product name is enough to start, a datasheet is better, and you'll get it back in writing.
