Do Paste and Liquid Colourants Affect Resin Curing?

← Back to What should be used to colour resin?

When adding colour to resin, it’s natural to wonder if paste or liquid colourants might affect how your resin cures. Let’s explore how different colourants interact with resin and what to keep in mind for best results.

How Colourants Affect Resin Curing

Paste and liquid colourants specially formulated for resin are designed to blend in smoothly without disturbing the curing process. When used within recommended amounts, they do not interfere with resin’s ability to set or harden. Overuse, however, can sometimes slow down curing or create cloudiness, so always measure carefully.

Guidance for Using Colourants in Resin

Choose colourants developed for resin, such as the Colourfun Set, for reliable performance.
Follow suggested dosages, usually only a few drops per 100g of resin, or as stated on your product’s instructions.
If aiming for strong shades, build colour gradually—excessive pigment can sometimes lead to softer cures or streaks.

When This Matters

Maintaining optimal curing is crucial for projects where clarity and hardness are essential, such as jewellery, river tables or transparent castings. Using suitable colourants in moderate amounts helps you achieve professional results that last.
