Abstract: Provided is a thermosetting resin composition which can suppress liquid dripping or bleeding from generating even when used for filling a hole in a printed wiring board having a large opening diameter of a hole part such as a through hole, and in particular, which can suppress cracks from generating even when used for filling a hole in a multilayer printed wiring board having a conductive part and an insulating part on the inner wall of a hole part such as a through hole. The thermosetting resin composition according to the present invention has a viscosity ratio R expressed by formula V2/V1 in the range of 5.0×10?2 to 1.0×102, wherein V1 (dPa·s) is the viscosity measured by a cone-flat plate type rotational viscometer (cone-plate type) in accordance with JIS-Z 8803:2011 and V2 (dPa·s) is the minimum value of the melt viscosity measured at 60° C. to 100° C.
Abstract: In an illustrative example, one or more coating formulations may be used and may have characteristics useful in different situations. During evaluations, a plurality of coating formulations comprising epoxy resins and diamine hardeners were prepared and evaluated with regards to impact ice adhesion strength and durability. Alone, such coating formulations provided a significantly reduced impact ice adhesion strength as compared to uncoated aluminum and/or stainless steel surfaces. However, a durability of the coatings, when applied to aluminum or stainless steel surfaces, was insufficient to be considered for use on external aircraft surfaces. By including nano-sized and/or micro-sized particles as additives to the coating formulations, resulted in improved durability without significantly reducing ice adhesion performance of the resin base.

Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.
