The process of adding pigment or dye to a synthetic resin, typically epoxy or polyurethane, alters its visual appearance. This modification enables the creation of colored castings, coatings, and decorative items. For example, dyes can be mixed into epoxy resin to produce translucent, vibrant art pieces, while pigments can be incorporated to achieve opaque and solid-colored functional parts.
Introducing color to resin expands its application across numerous industries and hobbies. It allows for customization, branding, and aesthetic enhancements in fields ranging from jewelry making and art to industrial coatings and prototyping. Historically, methods for altering the color of materials have been crucial for both practical and artistic purposes, with modern resin coloring techniques building upon this legacy through the use of advanced chemical formulations and precise application methods.
