Abstract: A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture as well as most of the interstices or openings, although some of the interstices or openings have holes where the coating does not completely fill in. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in any holes in the first coating. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. This substantially reduces pinholing.

This second coating is then partially cured, which advances the cure of the first coating past 80% full cure and results in an impregnated fiberglass cloth structure for use as sticker sheets.

Abstract: The invention relates to a process for producing loose fill in the form of spherical segments having a convex outer surface and a concave inner surface, and the granules formed. It is provided that starch granules are fed into a drum, and that in the drum, a nucleating agent is drum-coated onto the starch granules, and that the starch granules drum-coated with the nucleating agent are fed to an extruder, in which the starch granules are converted from their solid state into a viscous-liquid state. A starch foam created, by furnishing heat, in the extruder by the decomposition of the nucleating agent emerges from a forming opening of the extruder with a curved surface as a result of the difference in speed prevailing over the cross section of the composition, and that the skein of starch emerging from this forming opening is cut off directly at the forming opening, before any considerable expansion has taken place. The thus-created starch particles are received in a storage container.

Abstract: A multilayer adhesive construction and method for production of said construction are provided. The construction comprises a facestock, a barrier layer on the facestock, and an adhesive layer on the barrier layer. The barrier layer comprises a pressure-sensitive adhesive which inhibits the migration of mobile species such as oils, resins, tackifiers, or plasticizers from the adhesive layer into the facestock or from the facestock into the adhesive layer. This migration of mobile ingredients often manifests itself as swelling or hardening of the facestock which, in turn, leads to wrinkling of the adhesive construction and general loss of adhesion. The multilayer adhesive construction of the invention thus improves adhesion and the appearance of the label by inhibiting wrinkling and/or staining.
