A pre-pigmented white casting epoxy for river tables and furniture. EcoPoxy's data sheet gives a maximum of 38 mm (1.5 in) and a minimum of 13 mm (0.5 in) per pour, 7 hours of working time, and a 15 to 22 hour window for the next layer.

What the numbers mean for a pour
Pours needed with a limit of 1.5 in per pour. Worked out with the layer planner.
| Total thickness | Pours | Earliest start of last pour | Notes |
|---|---|---|---|
| 1 in (25 mm) | 1 | no wait (one pour) | – |
| 2 in (51 mm) | 2 | not calculated (see below) | – |
| 3 in (76 mm) | 2 | 15 h after the first, if the conditions below are met | – |
| 4 in (102 mm) | 3 | not calculated (see below) | – |
The published wait applies to a 1.5 in layer; your layers are 1 in. No schedule is calculated for a thickness the data sheet does not cover.
Only if these published conditions are met: pour the next layer while the previous one is tacky to touch (no abrading needed); same 14 L / 38mm test casting at 22°C (72°F)
The published wait applies to a 1.5 in layer; your layers are 1.33 in. No schedule is calculated for a thickness the data sheet does not cover.
What the manufacturer says
Paraphrased from the manufacturer’s documents.
Intended use
- SnowWhite is a pre-pigmented opaque white casting epoxy for river tables and large furniture, so no pigment needs to be measured.TDS
Heat
- Peak exotherm reached 99°C (211°F) in a 1.5 kg casting.TDS
- The cured resin has a glass transition temperature of 39°C (102°F), above which it may deform under load.TDS
Temperature
- EcoPoxy gives 22°C (72°F) as the ideal working temperature; the resin cures slower when cooler and faster and hotter when warmer.TDS
Layering
- For pours of 16 L or more, several thinner pours and fans blowing across the surface help prevent overheating.Page
- Pour the next layer once the first is tacky to touch; if it is no longer tacky, sand it with 220 grit and wipe it down first.Page
Other notes
- Mix the resin alone for 1 minute, then add hardener and mix 4-5 minutes; partial kits must keep the 2:1 volume (3.1:1 weight) ratio.Page
- SnowWhite does not shrink, but it can seep into cracks in live-edge wood, so the resin level may drop and need topping up.Page
- The TDS gives a theoretical cured density of 1.38 g/cm3; this is for cured resin, not the mixed liquid.TDS
- Store at 15-25°C (59-77°F); shelf life is two years unopened and 3 months once opened.Page
Safety data sheet summary
Signal word: DangerSDS B
Part A hazard statements
- H315 Causes skin irritation
- H319 Causes serious eye irritation
- H317 May cause an allergic skin reaction
Part B hazard statements
- H314 Causes severe skin burns and eye damage
- H318 Causes serious eye damage
Protective equipment
- Wear chemical-resistant, impervious gloves and inspect them before use.
- Wear safety glasses or goggles for the resin.
- For the hardener, wear side-shield safety glasses or goggles, consider a face shield for splashes, and wear full body protection.
- Wear an approved respirator if engineering controls do not keep airborne levels within limits.
- Emergency eye wash stations and safety showers should be close to where the product is used.
Ventilation
- Provide enough ventilation to keep vapor, mist and dust below workplace exposure limits.
- The hardener SDS gives the same ventilation instruction and says to use it only with adequate ventilation.
A summary, not the full SDS. Read the SDS for both parts before use and follow its first-aid section in case of exposure. This is not medical advice.
Where the manufacturer’s documents disagree
- Specific gravity or density, Part B: Specific Gravity Part B at 22°C (72°F) 0.978 (TDS) vs. Density 0.9658 g/cm3 (20 °C) (SDS Part B, section 9) (TDS, SDS B). The table shows the value from the TDS.
