Additive TI

Technical Datasheet | Supplied by Borchers
HSP Distance with AQUAPLUS™ PP: 1.0
Additive TI by Borchers is a p-toluenesulfonyl isocyanate. Acts as a moisture scavenger. Contains 100% active. It is soluble in many common solvents. It rapidly reacts with water and generates carbon dioxide, toluenesulfonamide which is chemically inert with alkyl and aryl isocyanates. Can prevent moisture related problems such as gloss reduction, haze, yellowing and bubbles from CO2 generation. It can also react with other active hydrogen chemicals such as alcohols, phenols, amines, amides, etc. Improves the storage stability of di-isocyanates against decomposition and discoloration. It does not cause yellowing of films. Recommended for 1K and 2K polyurethane based solvent borne coatings. Addition rate is 0.5-4.0 % of the total weight of the formula if the moisture content of the coating is 0.05-0.30 %.

Hansen Solubility Parameters

[19.4, 15.7, 7.7]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Additive TI. A practical determination of these HSP values would provide higher certainty. Learn More.
