A polyamide resin composition and a molded article manufactured using the same. The polyamide resin composition includes: about 40 wt % to about 60 wt % of a polyamide resin including a repeat unit represented by Formula 1 and a repeat unit represented by Formula 2 as defined in the specification; about 1 wt % to about 10 wt % of a maleic anhydride-modified olefin-based copolymer; about 5 wt % to about 20 wt % of calcium carbonate subjected to surface treatment with a silane compound; and about 20 wt % to about 40 wt % of glass fibers, wherein the silane compound includes a functional group comprising an amino group, an epoxy group, and/or a (meth)acryloxy group. The polyamide resin composition and the molded article produced using the same can have good properties in terms of plating adhesion, impact resistance, thermal resistance, and/or appearance, and the like.

An erosion resistant article such as rotor blades for helicopters and wind turbines having the leading edge surface protected from damage from high speed impingement of rain or sand with a protective coating formed from specific polyurethane or polyurea coating having a defined set of minimum physical properties where the protective coating can be applied as a liquid coating and cured in place or as a preformed complementary shaped covering to protect the leading edge against erosion damage in service.

A polyurea comprises at least urea base units of formula —NH—CO—NH— and additional units. The additional units comprise at least, on the one hand, a secondary alcohol functional group and, on the other hand, an ether, thioether or secondary amine functional group in the alpha position with respect to the secondary alcohol functional group. Such a polymer can be used as an adhesion primer for the adhesive bonding of a substrate, for example, glass or metal, to an unsaturated rubber or as corrosion-resistant protective coating for a metal substrate. Metal reinforcers, such as thread, cord, film or plate, coated can also be coated with such a polymer.

The invention relates to multilayer materials for producing packaging comprising at least two films and also a layer which is printed with a packaging printing ink, said packaging printing ink comprising a certain hyperbranched polyester containing functional groups. The invention further relates to a packaging printing ink which comprises a certain hyperbranched polyester containing functional groups, and to the use of said printing ink for producing multilayer materials.

The present disclosure provides a multilayered polymeric film for covering an agricultural structure or greenhouse, wherein the film contains adjacent layers that are capable of delamination from one another.

Building materials and methods of making a building material are disclosed. An exemplary method includes receiving algae; and subjecting the algae to an oil extraction process, in order to produce vegetable oil. The method further includes producing synthetic fibers by processing the vegetable oil from the oil extraction process; and processing the synthetic fibers to produce a tension and pressure resistant material.

The present invention relates to a multilayer barrier film capable of encapsulating a moisture and/or oxygen sensitive electronic or optoelectronic device, the barrier film including at least one nanostructured layer including reactive nanoparticles capable of interacting with moisture and/or oxygen, the reactive nanoparticles being distributed within a polymeric binder, and at least one ultraviolet light neutralizing layer comprising a material capable of absorbing ultraviolet light, thereby limiting the transmission of ultraviolet light through the barrier film.

The present invention provides a polyamide composition for a reflector having high heat resistance and good mechanical properties, having excellent adhesion to a sealing material for an LED package, and capable of retaining a high reflectance even after exposure to heat and light intended for the production process of the LED package and the environment in which the reflector is used in the LED package, when it is molded. The present invention is a polyamide composition for a reflector, containing: 30 mass % or more of a polyamide (A) having a melting point of 280° C. or higher; and 25 mass % or more of titanium oxide (B). The total content of the polyamide (A) and the titanium oxide (B) is 75 mass % or more.

In accordance with the present invention, compositions are described which are useful, for example, for the preparation of metal-clad laminate structures, methods for the preparation thereof, and various uses therefor. Invention metal-clad laminate structures are useful, for example, in the multi-layer board (MLB) industry, in the preparation of burn-in test boards and high reliability boards, in applications where low coefficient of thermal expansion (CTE) is beneficial, in the preparation of boards used in down-hole drilling, and the like.

Methods, systems and compositions for recovery of regenerant ions from spent regenerant solution by utilization of electrodialysis are provided. For example, in certain aspects methods for separating spent regenerant using an electrodialysis system comprising selective membranes are described. Furthermore, the invention provides methods for treating a friable solid ion-removal material to prevent fragmentation during regeneration.
