Patent number: 8864893Abstract: An aqueous binder composition is provided that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats.Type: GrantFiled: October 8, 2010Date of Patent: October 21, 2014Assignee: Owens Corning Intellectual Capital, LLCInventors: Christopher M.

Publication number: 20140298656Abstract: A method and an article of manufacture are disclosed for reinforcing various structures with only partially accessible circumference, such as columns closely adjacent to or protruding out of a wall or beams holding a ceiling. Some of these structures may be partly or completely submerged in water, such as retaining walls on the sides of rivers and water-ways. In some embodiments a prefabricated shell will fully or partly cover the exposed and reachable part of the structure and will be secured in place by various means. The shell may hug the structure tightly or loosely and the space between the shell and the structure may be filled with such curable materials as glue, epoxy, grout, concrete and the like. In various embodiments additional reinforcement such as rebar may be placed in the space between the shell and the structure.Type: ApplicationFiled: April 9, 2013Publication date: October 9, 2014Inventor: Mohammad R.

Publication number: 20140273686Abstract: A transparent composite substrate according to the present invention includes a composite layer containing a glass cloth formed of an assembly of glass fibers and a resin material impregnated in the glass cloth. The resin material has an Abbe number of equal to or larger than 45. The assembly of the glass fibers itself has a variation in a refractive index and a difference between a maximum value and a minimum value of the refractive index is equal to or less than 0.01. This makes it possible to provide a transparent composite substrate having superior optical characteristics and a high-reliable display element substrate using the transparent composite substrate. Further, the resin material preferably contains an alicyclic epoxy resin or an alicyclic acrylic resin as a major component thereof.Type: ApplicationFiled: November 6, 2012Publication date: September 18, 2014Applicant: SUMITOMO BAKELITE COMPANY LIMITEDInventors: Toshimasa Eguchi, Hideo Umeda, Manabu Naito, Hiroyuki Otsuka
