How to Use Plasticised Resin Safely

← Back to How is plasticized resin made?

When working with plasticised resins such as polyurethane or mineral-based casting products, safety should always be your top consideration. Following best practice for handling and application helps you achieve reliable results while keeping risks to a minimum.

Choose the Right Protective Gear

Most polyurethane resins are supplied as two components, and mixing them will release fumes and may cause splashes. Always wear suitable gloves and eye protection during mixing and pouring. If you’re working with solvent-based or highly fluid systems, a well-fitted respirator may also be sensible, especially in enclosed spaces. For water-based mineral resins such as NatuResin, the absence of solvents makes handling simpler and gloves may not be necessary, though they can still help you avoid mess and skin contact.

Safe Handling: Workspace and Mixing Tips

Set up a clean, well-ventilated workspace before you begin. Prepare all needed tools and follow the product instructions exactly, particularly with two-component polyurethane resins like IWhite Casting Resin. Measure and mix each part by weight as directed to prevent incomplete cures. Wipe up any spills immediately and avoid eating, drinking or smoking in your workspace. Dispose of leftover mixed resin and rinse containers according to local waste regulations.

When Safe Handling Matters Most

Proper safety steps are especially crucial during the initial mixing and pouring stages with polyurethane products, such as when using Polyform Casting Resin. Once fully cured, most resins are non-toxic to handle, but taking care during preparation protects your skin, eyes, and lungs from accidental splashes and vapours.
