← Back to What to harden resin?


Polyurethane resin is a versatile medium for crafting and model-making, but taking personal safety precautions is essential, especially during mixing and pouring.
Why Gloves Are Crucial
Uncured polyurethane resin typically contains isocyanates, compounds that can irritate the skin and cause sensitisation even with brief contact. Wearing appropriate chemical-resistant gloves (such as nitrile) forms an effective barrier between your hands and the resin, drastically reducing the risk of adverse reactions or contamination. Gloves should always be worn while handling both resin components, mixing, pouring, and cleaning your tools to promote safe crafting habits.


Additional Safety Measures
While gloves protect your hands, consider eye protection and good ventilation for added safety. Isocyanate vapours may irritate eyes or the respiratory system, so working in a well-ventilated space or using a suitable mask is wise, especially during larger pours or prolonged sessions. Always wash your hands thoroughly after working and avoid eating or drinking in your crafting area.
When This Matters Most
- Mixing and Pouring: Direct contact risk is highest—wear gloves throughout.
- Spill cleanup: Gloves prevent skin exposure to accidental drips.
- Sensitive users: If you have pre-existing allergies, take extra care or consult the safety datasheet for product specifics.
