Rather than sell a line of inks with a “One size fits all” approach, we work closely with each customer to design an ink for their specific needs. We routinely sign Non-Disclosure Agreements to protect the confidentiality of any information they disclose to us. After perusing our website, we encourage you to call us to discuss your application.
Dye Powders for Security Inks – Some customers have ink chemists on their staff, and prefer to buy just the dye powder, which they will formulate into their proprietary ink. Some of the considerations in selecting a dye for security inks are:

Solubility in the ink vehicle – this varies from dye to dye and should be tested.
pH of the ink vehicle – should be as close to neutral as possible. Acidic of basic environments will de-activate the dye.
Absorptivity – more absorptive dyes yield the desired result with lower concentrations and thereby impart less color to the ink.
Visible light transmission (VLT) – some applications require good VLT, and our dyes are industry leaders in this regard.
Some of the dye powders used in security inks are:
IR Dye 1310 – desired for its’ good absorptivity above 900 nm and good VLT.
IR Dye 1410 – excellent solubility in most ink vehicles.
IR Dye 2066 – can be used in lower concentrations, contributing less color.
Other dyes can be used in security inks, depending on the needs of the application.

AG IR Ink Transparent Light Green – broadly blocks infrared energy from 800 to 1100 nm, while still providing excellent visible light transmission. By modifying the concentration of the infrared dye, the infrared blocking needs can be balanced with you visible light transmission needs. Your Adam, Gates chemist will work with you to develop a formulation to meet your needs. To further meet your needs, this dye can be made available in a broad range of colors.
Cost Effectiveness – By working with your Adam, Gates chemist, we can develop inks which exactly meet your needs at the lowest cost of any inks on the market.
