Personalising your silicone erasers with colour or glitter opens up creative possibilities, but you’ll want to make sure your chosen additives are suitable for the specific silicone you’re using.
Choosing Compatible Additives
Not all pigments or glitters will mix well with silicone. Look for colourants and glitters that are clearly marked as silicone-compatible by the manufacturer. Unapproved additives could interfere with curing or produce an uneven finish. When introducing a new additive, always start by testing a small batch—this ensures you’re happy with the result and that the eraser cures correctly.
Mixing and Application Tips
Once you’ve selected your additive, mix it into the silicone base thoroughly before adding the catalyst or hardener. For liquid silicone rubber, even distribution is key to avoiding streaks or clumps, especially with glitter. Remember, overloading silicone with too much colour or glitter may affect the flexibility or curing. Generally, use pigments sparingly and opt for fine glitters rather than chunky varieties for a smoother eraser surface.
When This Matters
Adding colour or glitter makes most sense when crafting unique, personalised erasers as gifts, promotional items, or for creative projects where appearance matters just as much as function. It’s particularly relevant if you want classroom-friendly or themed shapes for children.
