How 99% Isopropyl Alcohol Helps in Epoxy Crafting
2. Helps Release Resin from Silicone Moulds – A light mist of IPA inside moulds can make demoulding easier, especially for moulds with tight, detailed sections.3. Cleans Tools, Cups, and Surfaces – 99% IPA dissolves resin before it cures, making it excellent for cleaning mixing sticks, silicone tools, measuring cups, and spills.4. Prepares Surfaces Before Pouring Resin – Because it evaporates cleanly and rapidly, 99% IPA is ideal for removing oils, dust, and contaminants before applying epoxy. A clean surface improves bonding and professional results.

How 99% Isopropyl Alcohol Helps in Gypsum / Eco‑Resin Crafting
While gypsum crafting doesn’t rely on IPA the same way epoxy does, it still has important uses:
1. Cleans Moulds Before Casting
IPA removes:
- dust
- oils from handling
- leftover release agent
- colour pigment residue
Clean moulds = no surface defects on your gypsum casts.
IPA is known to remove sticky residues and prep craft surfaces thoroughly.
2. Removes Pigment & Dye Residue
When working with gypsum pigments, alcohol helps clean:
- silicone moulds
- your work table
- tools such as spatulas, measuring spoons, stirrers
Its solvent properties dissolve leftover pigment effectively.
3. Helps With Fast Drying Clean‑ups
Because 99% IPA evaporates extremely fast, it allows you to:
- clean tools between colour batches
- switch pigments without washing with water
- maintain a dust‑free, residue‑free work area
This saves time especially when making multiple trays, coasters, or vessels.4. Removes Air Bubbles in Colour Mixes (MILD effect)
IPA is not as effective for gypsum bubbles as for resin, but a small spritz can:
- pop surface bubbles in pigmented water-based mixtures
- reduce pinholes on the top surface
Note works best when used lightly
Why 99% Instead of Lower Percentages?
- Evaporates faster → no water contamination in resin
- Leaves no residue → perfect for surface prepping
- Stronger solvent power → dissolves sticky resin before it cures
Safety Precautions for 99% Isopropyl Alcohol
1. Highly Flammable — Keep Away From Heat & Flames
99% IPA ignites very easily. Keep it away from:
- candles
- heaters
- sparks
- cigarettes
- hot tools
It must be stored in a cool, ventilated area and kept in a tightly sealed container.
2. Use in a Well‑Ventilated Space
The fumes can be harmful when inhaled. Avoid breathing in vapour directly and ensure good airflow when using it.
3. Avoid Skin Contact
99% IPA can cause:
- dryness
- irritation
- redness
It is too harsh for skin and should not be used on cuts or wounds.
Wear gloves if you are handling it often.
