FireGard® LT is a low-tint antimony trioxide synergist that offers color strength and opacity benefits.
FireGard® LT is similar to other St. Louis Group FireGard® grades and is used as a synergist in the presence of a halogen source. FireGard® LT is particularly effective in low-tint applications where color strength and opacity are important. The low surface area of FireGard® LT is useful in viscosity-sensitive applications and can be used with halogenated compounds or resins.
