1. Toxicity in Some Powder Coats - Why to Switch to non-TGIC
Contoocook, NH – June 9, 2014
As part of their objective to provide their customers with the highest quality materials, Prototek has recently learned of a toxic
chemical masquerading as a superior element providing desired characteristics in some powder coats.
This chemical is known as TGIC (triglycidyl isocyanurate), and has been added to some polyester powder coats to enhance its
cover and binder. TGIC’s effects, unfortunately, have also shown negative characteristics in lab tests. According to http://hse.gov.uk,
TGIC has a time-weighted average (safe exposure limit) of 0.1 mg/m^3 for 8 hours.
TGIC is classified under the Chemicals Regulation 2002 as toxic, irritant, sensitizing, mutagenic, and dangerous for the environ-
ment. It poses the risk of serious damage to eyes, toxic if inhaled or swallowed, causes skin to become overly sensitive, may cause
heritable genetic damage, harmful to aquatic organisms, may cause long-term adverse effects in aquatic environments, and more un-
desirable effects. It is for this reason that Prototek has made the decision to stop carrying TGIC powder coats.
Prototek will no longer be stocking TGIC powder coats as part of their Green Initiative, due to the harmful effects it has on its
employees and the environment. Many companies aren’t aware of the toxicity of this chemical on their fabricated parts, so Prototek will
begin requesting that customers’ prints and CAD files that request powder coats with the following designated characters switch over to
a non-TGIC powder coat alternative:
• Cardinal
Part numbers starting with a "T"
• Dupont
Part numbers starting with a "P"
• Sherwin Williams
Part numbers starting with a "P"
• Tiger Drylac
Part numbers starting with "#39" or "#49"
• Americoats
Part numbers starting with "T"
• Protech
Part numbers starting with "P"
• TCI
Part numbers starting with "9"
