Tone of Surface White

The tone of white for the standard board can vary between batches and is influenced by many factors, i.e. the pvc raw material, the percentage of CACO3, temperature, storage, formulation, machine run-out time etc.

Cleaning Treatment

NEMA boards and sheets are easy and fast to clean with a clean and/or damp cloth. If necessary one of many common household cleaners such as glass cleaners can be used. The cleaning solution should be applied and immediately wiped dry. No cleaning solution should be left to stand on the board for an extended period.

Harsh cleaners with glycol ethers or ethanol type solvents and/or isopropyl alcohol soften the coating if left on for several minutes. Citrus cleaners, abrasive cleaners and solvents such as acetone, paint striper and lacquer thinner are NOT recommended for cleaning.
