摘要:
Trimetallic nitride endohedral metallofullerene derivatives and their preparation are described. The trimetallic nitride endohedral metallofullerene derivatives have the general formula A3-nXn@Cm(R) where n ranges from 0 to 3, A and X may be trivalent metals and may be either rare earth metal or group IIIB metals, m is between about 60 and about 200, and R is preferably an organic group. Derivatives where the R group forms cyclized derivatives with the fullerene cage are also described.

摘要:
Disclosed are low temperature curable coating compositions, related coated substrates, methods for depositing a coating on a substrate and methods for refinishing the surface of an article, such as an automobile. The coating compositions include: (1) an aminofunctional silicon compound; (2) a polyether; and (3) a compound comprising functional groups reactive with the amino functionality of the aminofunctional silicon compound.
摘要:
Moisture-curable single-component (1K) coatings based on N-substituted urea polymers with extended chains and terminal alkoxysilane groups. The coatings are highly flexible, are gloss retentive, provide fast tack-free and dry-through times, provide high solvent resistance, and provide excellent exterior color stability to sunlight. The coatings can be formulated to produce high-gloss, semi-gloss and low-gloss finishes, and thus have application as both commercial and military coatings.
摘要:
A composition having: an amine-functional compound and an alkoxysilane-terminated polyurea made by reacting: an amino-functional alkoxysilane-polyisocyanate adduct with a difunctional amino- or hydroxyl compound. The composition contains no unreacted isocyanate groups. A coating composition having: an amine-functional compound, an alkoxysilane-terminated polyurea, and an epoxy- or acrylate-functional compound. The coating composition is a two-component system.
摘要:
A non-skid coating described herein attempts to overcome the deficiencies of the conventional coatings with improved external durability and color retention, a reduced level of VOCs, and direct-to-metal (DTM) adhesion using organo-siloxane chemistry. The non-skid coating has a first component having an amino-functional siloxane resin; a second component having a non-aromatic epoxy resin; a spherical filler for lowering viscosity; a pigment; a coarse aggregate; and a thixotropic agent. The amino-functional siloxane resin can be an amino-functional methyl phenyl polysiloxane, diphenyl polysiloxane or silsesquioxane-based resin. The non-aromatic epoxy resin can be cycloaliphatic or aliphatic. The first component is about 5% to 20% weight of the coating, and the second component is about 80% to 95% weight of the coating.
摘要:
The coating described herein attempts to provide this solution by synthesizing alkoxysilane-terminated N-substituted urea resins, then formulating them into moisture-curable single-component (1K) topside coatings. These coatings will provide greater external stability (to UV and visible radiation), cleanability, flexibility, cure times and lower VOC content than the currently qualified silicone alkyd topside coatings that are found on Navy ships. The single-component coating can include at least an alkoxysilane-terminated N-substituted urea resin, a reactive diluent, a pigment, a filler, and a catalyst. The resin can include an amino-functional silane substituted at the N-position and a non-aromatic isocyanate.
摘要:
A polysulfide coating composition includes an aliphatic, aromatic or cycloaliphatic material with at least 2 thiol groups; an aliphatic, aromatic or cycloaliphatic, acryl, polyester or polysiloxane-based material with at least two epoxy groups; and a catalyst. The coating provides a durable cavitation- and erosion-resistant coating for the rudders of ships, and is also suitable for sound-damping applications.
