In recent years, other manufacturers have produced and sold interlayers that do not have the same properties as SentryGlas®, but they are using the name “SGP” to refer to those interlayers in order to benefit from the long-standing quality and reputation associated with the SentryGlas® brand. Kuraray feels it is important for the glass industry to understand that authentic SentryGlas® products are not associated with SGP, and one should not expect SGP products to perform at SentryGlas® product levels.
Kuraray has now consolidated reference for SentryGlas® products as “SG™” and has recently obtained a US trademark registration for SG™.
While the acronym SGP was used when the product “SentryGlas® Plus” was first introduced by DuPont in 1998, the “Plus” was dropped from the name over 10 years ago.
Unfortunately, the SGP moniker has persisted in the industry, and its use is now causing confusion with authentic SentryGlas® products.
In order to avoid confusion, the proper designation SG™ should be used when requesting or referencing authentic SentryGlas® interlayers.
In addition to SentryGlas®, Kuraray also produces the next generation in the product line, SentryGlas® Xtra™ (SGX™).
