Ceiling tiles normally contain single or multiple coatings applied to a fiberboard substrate to enhance the final product properties. The coatings are composed primarily of inorganc pigments, like kaolin or calcium carbonate, and a binder system that holds the pigment to the ceiling tile surface.

Soy protein can be used in all coatings applied to ceiling tiles, prime and intermediate coatings. When incorporated into the coatings of ceiling tiles as a functional binder, Pro-Cote soy polymers provide the following benefits:

Strong pigment-fiberboard adhesion,

Excellent coverage of the fiberboard substrate,

Improved sag resistance and stability when exposed to high humidity,

Minimized formaldehyde emission.
