Air Drying an Acrylic Enamel

Henry V on Air Pollution Control

Here, at the turn of the century, air control is entering a

new time..Years from now your young

colleagues will ask about oh- nineThat time before things were so

clear.As you speak,

they will lean forward, straining to hear.

You’ll tell them how things wound up this way.

And they will hold their careers as

cheap, those who were not here,

To fight with us this day. 

Flip/flop an angle sensitive characteristic of metalliccoatings and a color match challenge

Clearcoat:Clearcoat:

•A Colorless Binder Strong Enough to Serve as a Topcoat Without the Reinforcement of a Pigment Providing a Wet Look to an Earlier Colorcoat

•Today More Than 60% of Factory Finishes are Color/Clear
