Abstract: A composition comprises, based on the total weight of the composition, 50 wt % to 90 wt % of a polyetherimide; and 10 wt % to 50 wt % of a filler comprising talc, titanium dioxide, zirconium oxide, neutral aluminum oxide, or a combination comprising at least one of the foregoing; wherein the composition has a number of drops to tracking at 250 volts of greater than or equal to 50 drops determined according to ASTM D-3638-85.
Abstract: The present disclosure relates to a solvent-containing dry film and a method for applying a dry film on a substrate. The dry film includes a carrier and a resin layer. The resin layer contains a resin composition and a solvent and the solvent is present in a total amount of at least 5 wt % based on the total weight of the resin layer. The dry film of the present invention can be applied onto a substrate without the use of a prior art vacuum lamination apparatus. The application process is simple and is more cost-efficient than the prior art techniques.

Abstract: An article includes a plurality of stacked sheets. Each sheet includes a film having a first side, with a print receptive or primed layer, and a second side, with an optional release treated layer; and a bonding layer that is coated at 100% solids on the first side of the film to releasably attach a second side of a film of an overlying sheet to the first side of an underlying sheet. Each sheet is stacked upon another sheet such that except for a topmost sheet of the stack the bonding layer is in contact with the second side of a film of an overlying sheet. The bonding layer of the topmost sheet defines an outer surface of the stack that protects the topmost sheet of the stack from environmental damage.
Abstract: Flexible films of thermosetting adhesive materials which are non-tacky to the touch are storage stable at room temperature and can be cured at elevated temperature with a short cure time and can be cured to produce a tough flexible adhesive layer including bonding to oily surfaces, the materials are particularly useful in bonding together dissimilar substrates.

Abstract: Flexible films comprise an adhesive layer and a fibrous supporting layer and the thermosetting adhesive materials which are non-tacky to the touch are storage stable at room temperature and can be cured at elevated temperature with a short cure time and can be cured to produce a tough flexible adhesive layer including bonding to oily surfaces, the materials are particularly useful in bonding together dissimilar substrates where they can reduce the formation of galvanic corrosion.
Abstract: Provided is a polyimide resin composition capable of forming a polyimide film which is excellent in transparency and heat resistance and has a low thermal linear expansion coefficient. The polyimide resin composition contains a polyimide resin produced by reacting (A) a tetracarboxylic dianhydride with (B) a diamine containing a phenolic hydroxyl group-containing diamine in an amount of from 5 to 100 mol % of the total diamine; and silica microparticles, in a ratio by mass of from 25/75 to 60/40.
Abstract: A resin composition comprising one or more cyanate compounds (A) selected from a group consisting of a naphthol aralkyl-based cyanate compound, a naphthylene ether-based cyanate compound, a xylene resin-based cyanate compound, a trisphenolmethane-based cyanate compound, and an adamantane skeleton-based cyanate compound; a polymaleimide compound (B) represented by general formula (1); and a filler (C).
Abstract: An article comprises a carbon fibre reinforced plastic (CFRP) substrate, a buffer layer disposed adjacent the substrate, the buffer layer comprising a poly(para-xylylene) polymer; and a moisture barrier coating disposed adjacent the buffer layer.

Abstract: Disclosed is a polyimide precursor composition for the production of a flexible board of a photoelectronic device. The polyimide precursor composition includes a polyimide precursor derived from a diamine or acid dianhydride including a structure of Formula 1: wherein R1 to R8, m1, m2, and m3 are as defined in the specification. Also disclosed is a polyimide film produced from the polyimide precursor composition. The polyimide film is obtained by applying the precursor composition to a substrate and curing the composition. The polyimide film has high transparency and good heat resistance. In addition, the polyimide film exhibits good dimensional stability because the substrate does not undergo an increase in stress even during high-temperature heat treatment.
