Additive TI Monofunctional isocyanates
Description
Additive TI is a Highly reactive, low viscosity monofunctional isocyanate. It reacts with water to form an inert amide.
Additive TI can eliminate the Very little moisture, thus preventing problems caused by moisture during the preparation of polyurethane paints.

Performance
Additive TI It can be used as a dehydrating agent for solvents, fillers, pigments and asphalt tar, etc. It reacts rapidly with water to form carbon dioxide and toluenesulfonamide, which generally does not react further with alkyl or aryl isocyanates and is soluble in common solvents. In addition, Additive TI does not cause yellowing of the coating film.
used in polyurethane systemAdditive TI can avoid problems such as loss of light, fogging, yellowing and reaction bubbles caused by moisture in the system.
Additive TI It can also react with other compounds containing active hydrogen, such as alcohols, phenols, amines, amides, etc.
Apply
Additive TI Used in one- and two-component polyurethane systems, it can eliminate the moisture introduced by solvents, pigments and fillers.
<span style="col. In poorly ventilated operating environments, use a respirator. An oxygen supply mask or a filter mask with combination filter A2-P2 is recommended.
Contaminated skin should Wash off immediately with plenty of water and soap. Contaminated clothing should be changed promptly. If Additive TI gets in eyes, rinse thoroughly with water and seek medical attention. If you accidentally inhale high doses of Additive TI fine particles or vapor, you need to treat according to the irritation symptoms of the respiratory tract (the same as the treatment of irritation symptoms caused by inhalation of irritating substances), and seek medical attention. Disposal of this product residue is subject to the following rules:
Drain container completely residue, do not wash container with water. Additive TI flowing on the ground and on the laboratory table can be washed off carefully with water or covered with the following paste. Empty containers should be cleaned with the following solution or left open in a safe place for several days. Due to the high reactivity of monofunctional isocyanate with water, the residue will gradually transform into a white solid substance after reacting with moisture in the atmosphere.
100g solution is enough to make about 42 g Additive TI Reaction
