Before You Search for the 'Best' Epoxy Resin
If you've ever typed 'whats the best epoxy resin' into a search bar and gotten twenty different answers, you know the feeling. I get it. I'm a procurement specialist who handles chemical orders for a living—six years in. I've personally made (and documented) 16 significant mistakes, totaling roughly $12,000 in wasted budget. Now I maintain our team's checklist so nobody else repeats them.
This checklist is for three kinds of people:
- Crafters choosing a tabletop, casting, or jewelry resin.
- Small shops comparing resin distributors and trying to figure out if a specialty chemical company like Lanxess is relevant to them.
- Anyone who landed here by accident while looking for 'Virkon S SDS Lanxess.' That's a disinfectant, not a resin, but I'll get to that.
First, a quick Lanxess company overview chemical industry note. Lanxess is a German specialty chemicals company with a broad portfolio—flame retardants, lubricant additives, biocides, rubber chemicals, resins, and disinfectants like Virkon S. It sells through B2B channels, so if you're a craft buyer, you probably won't order from them directly. But if you're evaluating suppliers, Lanxess is one of the big names you'll see in raw material sourcing. None of that helps you pick a craft resin though.
It's tempting to think 'best epoxy resin' is a stable, searchable category. It's not. The best resin is the one that matches your specific pour.
The Checklist: Six Steps Before You Buy
Run through these in order. It takes about twenty minutes the first time.
Step 1: Define your actual pour
Are you coating a tabletop, casting a paperweight, or doming a badge? These are different jobs. A tabletop resin is made for thin, self-leveling layers. A casting resin is made for thicker pours. A doming resin is formulated to hold a dome shape without running.
The mistake I see is using a coating resin for a thick casting and then wondering why it overheats or cracks. If your search is 'how to suspend objects in epoxy resin,' you're almost certainly in casting territory, which means you'll need a resin with a low-enough viscosity to release bubbles and a long-enough working time. (More on that in Step 4.)
If the label doesn't say max pour depth, call the supplier before you buy. That's a red flag.
Step 2: Read the SDS and the tech data sheet
Two documents, not one. The safety data sheet (SDS) tells you about hazards and protective equipment. The technical data sheet (TDS) tells you mix ratio, working time, max pour depth, and cure schedule. Most people only read the SDS when they're forced to, and many never look at the TDS.
Here's something vendors won't tell you: the 'working time' printed on the label is optimistic. It's usually measured at 25°C in a thin layer, not in a mixing cup during summer. If you're working in a warm room, your working time is shorter. If it's cold, the resin gets thicker and harder to use.
And if you were searching 'Virkon S SDS Lanxess'—stop. Virkon S is a disinfectant used in veterinary and facility hygiene, not an epoxy resin. If you need the real SDS, get it from the official Lanxess product page or your supplier, and don't use an old cached copy from a random website.
Step 3: Compare cost per usable volume, not per kit
When you search 'craft resin epoxy resin price,' you'll see kits from maybe $22 to $60 for 16 ounces (based on a quick scan of U.S. online listings in February 2025; verify current pricing). That's a wide range, and the most expensive kit isn't automatically the best.
Convert every option to cost per ounce or per milliliter, then compare that with the resin's intended use. A cheap resin that's wrong for your project is not a bargain—it's a future headache. A more expensive resin with a longer working time can be a no-brainer for deep pours because it gives you time to place objects and pop bubbles.
On the B2B side, here's another insider thing: the first quote is almost never the final price for an ongoing relationship. If you're buying resin in bulk from a distributor, you can usually negotiate once you've proven you're a reliable customer. But don't pick a supplier just because its first number is low. Price per drum matters, but so does consistency.
Step 4: Suspend objects the slow way
If you want to know how to suspend objects in epoxy resin, the answer is layers. Don't drop a coin into a full mold and hope it stays where you want.
Here's the process I use:
- Pour a thin bottom layer into the mold, about 1/8 to 1/4 inch, depending on the object's weight.
- Let it cure until it's firm enough to hold the object. If the object is heavy, wait for a full tack-free cure, not just a skin.
- Place the object, then pour a second thin layer to cover it. Let that cure enough so the object doesn't float or shift.
- Repeat until you reach the desired depth.
What most people don't realize is that 'cured' on a label can mean two different things. A resin may feel hard after 24 hours but still need seven days to reach full mechanical strength and clarity. If you sand or demold too early, it can look fine for a week and then fog or bend. If your resin has a stated maximum pour depth, don't push it. I once made an $890 mistake by testing a 'deep-pour' resin in a layer that was twice the stated max. It cracked. Actually, the resin cost $240; the wasted time and labor made it $890. I still have the spreadsheet.
Step 5: Mix a small test pour first
This sounds like a no-brainer. I've still skipped it more often than I'd like. A 100-gram test pour, using your actual mold and your actual room temperature, will tell you more than any online review.
Check for: bubbles, color shift, cure time, hardness, and whether the surface is sticky after the stated time. If the test piece is a mess, you just saved yourself a $60 resin kit or a $3,200 production order. Trust me on this one.
Step 6: Control your workspace
Epoxy doesn't like surprises. Temperature, humidity, and dust affect the final result. If the room is below the minimum temperature on the TDS, the resin may not cure properly. If it's humid, you can get a cloudy surface. If you're sanding, wear a mask and collect the dust—doesn't matter if it's 'craft resin' or an industrial system.
Also, don't mix more than you need. Epoxy generates heat while it cures. In a thick container, a big batch can get hot enough to crack the cup. If you're working with a fast hardener, small batches are especially important.
Notes and Common Mistakes
Here's the stuff that doesn't fit neatly into a step:
- Always prepare 10% extra resin when pouring into a mold. Running out and mixing a new batch halfway through creates a visible seam.
- Don't move the piece while it cures unless the resin has been designed to be moved. Movement causes wave marks and bubbles.
- If you sell finished pieces, don't slap 'food safe' or 'non-toxic' on the listing without evidence. Per FTC advertising guidelines (ftc.gov), claims need substantiation. That's not just a marketing preference.
- Don't choose a resin because a famous craft account made something pretty with it. They may have used a pressure pot or a different hardener.
Bottom line: the best epoxy resin is the one that fits your process, not the one that ranks first in a search result.
This checklist has caught at least 40 potential errors for our team in the past 18 months. Maybe 47, I'd have to check the log. Either way, I'd rather spend ten minutes at the start than deal with a ruined pour and a disappointed customer. That's the whole point.
