摘要:
Sealant and potting formulations comprising a thioether-functional, oligomeric polythiol prepared by reacting together: (a) a compound having at least two thiol functional groups; and (b) a compound having triple bond functionality are disclosed.
摘要:
A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.
摘要:
An aqueous electrocoating composition useful in a method of electrodeposition contains an electrodepositable resin, optionally a curing agent and a microparticulate crosslinked unsaturated polyester flatting agent. The microparticulate flatting agent provides the desired flatting effect without compromising coating properties such as corrosion resistance and flexibility.
摘要:
Disclosed are particles that have an exterior surface coated with a thin polymeric coating, such as a coating that includes a sulfur-containing polymer. Also disclosed are compositions, such as fuel-resistant sealant and coating compositions, which include such particles. Aerospace vehicles having an aperture at least partially sealed with a sealant deposited from such a sealant composition are also disclosed.
