GLH HARDENER 50G

GLH Hardener is a precision-formulated component specifically designed for use with Marabu GL Series glass inks. Engineered to optimize performance on glass substrates, this hardener ensures exceptional adhesion, durability, and long-lasting print quality when used correctly. It is essential for applications requiring strong, reliable results on smooth, non-porous surfaces such as glassware, mirrors, or coated metals.

Before adding thinner, GLH Hardener must be stirred thoroughly for approximately 5 minutes to ensure an even consistency and optimal activation. It should be mixed with Marabu GL inks at a recommended ratio of 5% by weight. This measured approach guarantees balanced curing and maximum bonding strength between the ink and the substrate.

GLH Hardener offers a working pot life of approximately 8–10 hours, giving printers ample time for precise application without the need to rush. However, this hardener is sensitive to humidity, which can impact performance—so careful storage and usage in controlled environments are advised.

Ideal for decorative and functional glass printing, GLH Hardener is trusted by professionals for high-end printing results. When paired with Marabu GL inks and proper printing procedures, this hardener ensures crisp, durable, and professional-quality prints every time.
