REACTION RATIO

The reaction ratio is calculated from the respective equivalent weight or hydroxyl and isocyanate content of the reactants.Conventional polyisocyanates such as Desmodur N75 and AR - 75 can be used successfully.

CATALYSTS

To increase the initial rate of cure of Macryl 8649 70% based paints, at both ambient temperature and under lowbake conditions, the use of tin catalyst in the form of Di Butyl tin Di Laurite is strongly recommended

SOLVENTS

The solvents chosen for paints and lacquers based on Macryl -864970% should be free of water and should notcontain groups that react with isocyanates. Ester and Ketones are True solvents and aromatic hydrocarbons are used as diluentsfor this system.

Applications

PU Automotive Paint

The interiors and exteriors of trucks and cars feature many plastic parts. Depending on where the parts are located and what types of plastics are used, they may be protected with a variety of coating layers. Polyurethane (PU) systems provide a long-lasting, high-quality finish regardless of the number of layers.

Baking Alkyd Resin

Alkyd resins are manufactured from the condensation reaction between oil or polyols, acids, and alcohol. They are typically used as binders for coatings and printing inks. For lacquers in particular, nitrocellulose (NC) and CAB with excellent drying properties are used in combination with short oil alkyd resins that have low content of used oil.
