Epolight™ 7276C by Epolin is a visible opaque dye. Also known as near infrared cut on filters or long wavelength band pass filters. They are designed to block UV and visible light i.e. (350 to 650 nm ) while transmitting NIR (near infra red) light above 700 nm. It appears as an orange-brown powder. Epolight™ 7276C is suitable for injection molding but not for coatings. Epolight™ 7276B by Epolin is a visible opaque dye. Also known as near infrared cut on filters or long wavelength band pass filters. They are designed to block UV and visible light i.e. (350 to 700 nm) while transmitting NIR (near infra-red) light above 750 nm. It appears as a red-brown powder. It is suitable for injection molding but not for coatings. Epolight™ 5547 Near Infrared Dye by Epolin exhibits very high absorptivity. Possesses insolubility in water. Suitable for acrylic thermoplastics. Tris amminium structure. It provides an excellent visible light transmission for a monovalent amminium dye.
