    Abstract: A two-part curable composition comprises: a Part A component comprising polythiol having a thiol group functionality of at least two, and tertiary amine accelerator; and a Part B component comprising polyene comprising at least two of non-aromatic C—C double bonds, C—C triple bonds, or a combination thereof and organic peroxide curative. At least one of the polythiol or the polyene comprises a respective reaction product of reaction components comprising: HSR1O(CH2CHR2O)aR1SH wherein each R1 independently represents an alkyl group having from 2 to 12 carbon atoms, each R2 independently represents H or CH3, and a represents an integer from 1 to 20; triallyl isocyanurate; H2═CHOR1O(CH2CHR2O)aR1OCH═CH2; and. A method of making a curable composition comprises combining the Part A and Part B components of the two-part curable composition. Methods of sealing a substrate and adhering two substrates, and articles made thereby are also disclosed. (Formula AA)

    Abstract: Methods for making structural shims (220) for the mating assembly of parts, such as for installation between a skin (212) and substructure (214) of an aircraft. The methods include the steps of disposing a hardenable composition (216) into a gap between the first (212) and second parts (214), hardening the hardenable composition to provide a shim pattern (218) that is dimensionally stable, and removing the shim pattern from the gap without damage. The shim pattern can be used to provide a digital model thereof, which can in turn be used to fabricate the structural shim (220).

    Abstract: Curable sealant compositions comprise the components: a) x weight percent of at least one polythiol; b) y weight percent of at least one unsaturated compound having at least two non-aromatic carbon-carbon double bonds, at least one carbon-carbon triple bond, or a combination thereof; c) from 0.01 to 8 weight percent of at least one quaternary ammonium or phosphonium salt; d) from 0.05 to 10 weight percent of at least one organic peroxide; and e) optionally from 0.01 to 10 weight percent of a photoinitiator system capable of generating free radicals upon exposure to actinic radiation. Each of x and y represents a positive real number. The sum x+y is in the range of 72 to 99. The weight percent ranges of the components a)-e) are based on the total weight of the components a)-e). A seal cap including the curable sealant composition and methods of making and using the curable sealant compositions are also disclosed.

    Abstract: Polythioether polymers, sealants containing polythioether polymers, and compounds useful as stabilizing monomers in the manufacture of polythioether polymers are provided. In many embodiments the polymers and sealants demonstrate reduced risk of spoilage that may be caused by low temperature storage of the polymer or uncured sealant. Compounds useful as stabilizing monomers include compounds according to formula I: CH2═CR1—CHR2—S—R3—S—CHR4—CR5═CH2  [I] wherein R1, R2, R4 and R5 are independently selected from —H, —CH3 or —C2H5, and wherein R3 is selected from divalent groups comprising 2-12 carbon atoms, 0-5 ether oxygen atoms and 0-5 thioether sulfur atoms, which may be straight, branched or cyclic.

    Abstract: The present disclosure provides methods and articles useful in sealing fasteners, including seal caps and methods of their use, and in particular light weight seal caps having higher dielectric breakdown strength, lower weight, and/or lower wall thickness. In some embodiments, the seal caps according to the present invention are made of a material having a dielectric breakdown strength of greater than 1.0 kV/mm, in some embodiments greater than 15.0 kV/mm, and in some embodiments greater than 50.0 kV/mm. In some embodiments, the seal caps according to the present invention are thin-walled, having an average wall thickness of less than 1.5 mm and in some embodiments less than less than 0.5 mm. In some embodiments, the seal cap comprises a polyurethane polymer, a polythioether polymer, a polysulfide polymer, a fluorinated thermoplastic polymer, a THV polymer, a fluorinated thermoset polymer, an engineering thermoplastic, and/or a PEEK polymer.
