B05D 1/36

US Classification:

428426, 4274071

Abstract:

A thin drywall board that includes a gel coat, at least one polymer/gypsum layer, and a wet glass fiber layer is provided. The gel coat is formed of a gel coat composition that includes a water dispersible polymer, gypsum, and optionally a crosslinking agent and/or a coupling agent. The polymer/gypsum layer is formed of a matrix composition that includes a water dispersible polymeric resin and gypsum. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the matrix composition. The wet glass fiber layer is preferably a glass fiber mat. The combination of the water dispersible polymeric resin and the gypsum in the matrix composition have a synergistic effect that creates a thin drywall board that is water resistant, fire resistant, and has improved mechanical properties. A method of forming the inventive thin drywall boards is also provided.

Abstract:

An optical cable reinforcement in the form of glass fiber strands �30! having a first coating �32! of a binding agent such as a latex mixture and a second coating �34! of particles �36! of a water blocking agent such as a polyacrylate salt. The particles �36! of water blocking agent are adhered to the glass fiber strands �30! by the binding agent without the binding agent entirely coating the particles of water blocking agent. The unoccluded surface areas of water blocking agent thus provided serve to rapidly absorb/desorb water and protect the optical cable from moisture. A unique powder coating station �60! is used to apply the particles �36! of water blocking agent to glass fiber strands �30! which have been coated with wet binding agent so that the proper adherence of the particles �36! of water blocking agent without complete embodiment, is obtained.

Abstract:

An aqueous post-coat composition for coating a fiber tow is disclosed. The aqueous composition includes about 0.5 to about 5.0 wt. % solids of a film former and about 0.05 to about 2.0 wt. % solids of a compatibilizer. The compatibilizer may be at least one of a silicone-based coupling agent, a titanate coupling agent, a zirconate coupling agent, gluteric dialdehyde, and a quaternary ammonium antistatic agent.
