TGICvapaat

TGICvapaat is a term used in some Finnish-language contexts to denote products, particularly coatings or resins, that are free of triglycidyl isocyanurate (TGIC). TGIC is a trifunctional epoxy crosslinker that has historically been used in epoxy resins and TGIC-containing powder coatings. Due to concerns about potential health risks such as skin sensitization, TGIC-free formulations—often referred to in industry as TGICvapaat—are marketed as safer alternatives.

In production, TGIC-free formulations replace TGIC with alternative crosslinkers or resin systems, such as non-TGIC epoxy, polyurethane, or acrylic crosslinkers. This substitution can require adjustments to curing schedules and formulations to achieve comparable performance. Modern TGIC-free coatings aim to maintain properties such as adhesion, hardness, chemical resistance, and weatherability, while avoiding TGIC-related concerns.

Applications for TGICvapaat formulations are wide and include architectural and decorative metal coatings, automotive and appliance finishes, and general industrial coatings where long-term durability and safety are priorities. The TGIC-free designation is often used in European and Nordic markets as part of broader moves toward safer consumer and industrial coatings.

Testing and compliance typically involve supplier declarations and, where necessary, analytical verification to confirm the absence of TGIC. Independent laboratory certification or adherence to industry safety schemes may accompany product literature and safety documentation.

Limitations and considerations: TGIC-free does not automatically guarantee superior performance in all conditions, and formulation choices continue to influence cure behavior, appearance, and lifecycle performance. Users should consult manufacturers’ data sheets for specific properties and compatibility with substrates.
