MSDS Sheets All marking
chalk is not created equal. The color and the amount of the pigment
determines the vividness of the line. The pictures on the right
give a basic idea of how marking chalk works and why Keson chalk is
the best marking chalk in the world. It sticks to your line until
you decide you want it to stick to something else. Over the years,
we’ve fine tuned our formulas to produce chalk that performs
consistently and excellently, batch after batch. We’ve
engineered a range of colors with two basic variations of
intensity: Perma-Mark®, for lines that hit and stick for a long,
long time; and Ultra-Fine® for your basic chalk line needs. The
Glo-Orange is a highly visible version of regular chalk that will
wear or wash away naturally.
