Latest Patents
Eby's latest patents showcase his ingenuity and focus on improving product functionality. One of his noteworthy inventions is a **lightweight joint compound having improved paintability**. This compound integrates expanded perlite coated with a special composition, rendering it impervious to water. The perlite is ground prior to expansion, achieving a mean particle size of approximately 50 to 70 microns. This advancement leads to greater uniformity in paint gloss appearance between the joint compound and the gypsum wallboard surfaces, providing an aesthetically pleasing result post-application.
Additionally, Eby has developed a **kerfed edge gypsum board having improved edge strength**. This innovative gypsum board features a kerfed edge along nearly its entire length, where the kerf walls incline inward without intersecting. Characterized by a bottom surface with alternating projections and depressions, this design enhances strength in a perpendicular direction, thus improving the board’s retention by flanged supports compared to traditional sawn kerfed edge boards. Eby’s process for producing this kerfed edge is dustless, ensuring a clean and efficient manufacturing method.
