What the numbers mean for a pour

Automatic planning is suspended for this product: its documents give more than one depth limit (1/8 in, 1/4 in) for different applications or sources, and we do not choose between them. Read the published wording and enter the limit that fits your project in the layer planner.

What the manufacturer says

Paraphrased from the manufacturer’s documents.

UV and color

The resin has UV inhibitors but is not meant for permanent outdoor use or direct UV exposure, and it will eventually yellow.TDS

Heat

The TDS lists a temperature resistance of 130°F.TDS
The FAQ puts heat resistance at 120°F (57°C) once fully cured and recommends coasters.FAQ

Layering

Pours thicker than 1/8-1/4 in need multiple coats; pouring thicker generates excess heat, bubbles, cracking and shrinkage.FAQ

Surface preparation

Brush on thin seal coats 3-4 hours apart and wait 6-8 hours after sealing before the flood coat.FAQ
Do not pour over bark or directly over oil-based paint or stain; seal paper items before embedding.TDS

Temperature

For pours of 2 gallons or more, keep the room closer to 65°F and run fans.TDS

Other notes

The TDS lists tensile strength 3682 psi, elongation 16%, flex strength 4472 psi and compression 109,000 psi.TDS
The product page states 'FDA Compliant per FDA 300' when the epoxy is properly measured, mixed and fully cured.Page
Shelf life is given as 1 year.TDS

Safety data sheet summary

Signal word: DangerSDS B

Part B hazard statements

H302 Harmful if swallowed
H312 Harmful in contact with skin
H315 Causes skin irritation
H317 May cause an allergic skin reaction
H318 Causes serious eye damage
H361 Suspected of damaging fertility or the unborn child

Protective equipment

Wear impervious gloves such as butyl or nitrile rubber.
Wear chemical safety glasses or goggles.
If ventilation is inadequate, use a fitted NIOSH-approved air-purifying respirator with organic vapor cartridges; supplied air for high exposures.

Ventilation

Use with adequate general or local exhaust ventilation to keep exposure low (both parts).

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

Recommended temperature: ideal working temperature around 65-75°F (TDS) vs. Optimal product working temperature is 75°F–85°F; cure 72 hours at 75°F–85°F (FAQ) (TDS, FAQ). The table shows the value from the TDS.
Working time: Work Time (100 gram mass) 30-45 minutes (TDS table) vs. you’ll have about 35 minutes (TDS body text) (TDS, TDS). Both statements are in the TDS; the table shows “30-45 minutes”.
Full cure: Full Cure Time 3-5 days (TDS table) vs. Full cure and maximum hardness can require up to 5 days (TDS Step 5) vs. The curing process for our table top epoxy is 72 hours (product page) (TDS, TDS, Page). The table shows the value from the TDS.
Temperature resistance: Temperature Resistance 130F (TDS) vs. heat resistance once fully cured is 120°F/57°C (FAQ) (TDS, FAQ).
