Gravity polyaspartic polyuria resin has certificate FDA ROHS and is ECO – FRIENDLY. This means the application technician and generaly every human, animals and the environment are free of any emmissions and other unhealthy chemicals. This applies for before, during and after the application.

Some resins — especially cheaper industrial types or those not intended for interior use — can release harmful chemicals even after they appear to be “dry.” Not all cured resins are safe for humans.

Types of Resin & Their Safety After Curing

Resin Type Safe After Curing? Notes

GRAVITY POLYASPARTIC POLYUREARESIN
(high quality, ECO – FRIENDLY , ROHS, VOC-free) Generally safe Must be fully cured; low-VOC brands are best for indoors & outdoor.

EPOXY / Polyurethane Depends on formulation Some release isocyanates during curing; good ventilation required. After curing, good quality ones are safe — but cheap ones can still off-gas.
Polyester Resin (Fiberglass type) Not recommended indoors Even after curing, it can continue to release styrene fumes.
Acrylic Resin Safe when cured Common in solid surfaces and bathtubs.
Industrial or Solvent-Based Resins Risky Some never fully stabilize and continue off-gassing.

So Your Question:

Yes — there are resins that even when dry are not safe for humans, especially:

Polyester/Fiberglass resin — still releases styrene fumes after curing.

Cheap polyurethane or industrial floor resins — may release isocyanates or solvents if low-grade.

UV resin (craft type) — if not cured properly, remains toxic to skin.
