Abstract
Described herein is a two-component coating system. The two-component coating system may include a base component and a hardener component. The base component may include: up to 55 wt. % hydroxyl terminated polyester and/or hydroxyl terminated polyether; up to 3 wt. % hydroxyl terminated polysiloxane; and a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the hydroxyl terminated polyester and/or hydroxyl terminated polyether and the hydroxyl terminated polysiloxane are dissolved in the solvent. The hardener component may include: up to 80 wt. % polyisocyanate; and a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the polyisocyanate is dissolved in the solvent.
Claims19
A two-component coating system comprising a base component and a hardener component, the base component comprising:
- up to 55 wt. % hydroxyl terminated polyester and/or hydroxyl terminated polyether;
- up to 3 wt. % hydroxyl terminated polysiloxane;
- a moisture scavenger;
- and
- a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the hydroxyl terminated polyester and/or hydroxyl terminated polyether and the hydroxyl terminated polysiloxane are dissolved in the solvent,
- the hardener component comprising:
- up to 80 wt. % polyisocyanate;
- and
- a solvent selected from aromatic hydrocarbons, ketones, esters and combinations thereof, wherein the polyisocyanate is dissolved in the solvent;
- wherein the solvent of the base component comprises about 18 wt % to about 23 wt % ethyl acetate, about 22 wt % to about 27 wt % glycol acetate, and about 2 wt % to about 4 wt % methyl ethyl ketone;
- or the solvent of the hardener component comprises about 5 wt % to about 7 wt % ethyl acetate and about 13 wt % to about 18 wt % glycol acetate.
