Isopropyl alcohol is a popular companion for resin crafters, valued for its cleaning and bubble-removing power. However, safety is crucial whenever flammable substances are involved. Here’s how to use it confidently during your next epoxy project.
Safe Handling Basics
Always work in a well-ventilated area. This will help reduce inhalation of fumes and keep your workspace pleasant. Store isopropyl alcohol in its original container, tightly sealed, and clearly marked to prevent accidental misuse. Never allow the liquid or its vapour near flames, hot elements, or sources of sparks, as pure isopropyl alcohol is highly flammable. It is wise to keep a fire extinguisher nearby when using large amounts in your craft area.
Application Tips for Resin Work
If you’re using isopropyl alcohol to remove bubbles or clean moulds—for example, with Pure Isopropyl Alcohol 99.9%—apply it sparingly and give surfaces ample time to air dry before heat-treating or demoulding. Residual alcohol can react dangerously if exposed to a heat gun or flame too soon. Disposable gloves are recommended to prevent skin dryness or irritation.
When This Matters Most
Pay close attention to these precautions if you’re working indoors, have limited ventilation, or use any direct heat methods on your resin pieces. Vigilance is especially important during busy workshops or when sharing space with others.
