Patent number: 9796802Abstract: The present invention is directed to resins made from cashew nutshell liquid and vinyl hydrocarbons and processes for manufacturing the resins. These resins exhibit lower viscosity than the phenol-based homologs. They also exhibit good compatibility with a wide range of solvents, mineral and natural oils, epoxy curing agents, liquid epoxy resins, and polymers, which make them suitable additives as non-reactive diluents for solvent-free coating formulations; tackifiers for structural adhesive, pressure sensitive and hot-melt adhesives; stabilizers for lubricants, fuel and polymer formulations; plasticizers for thermoplastic polymers and processing aid for rubber compounding and stabilizers for respective rubber artifacts. These resins are also valuable precursors for the manufacture of epoxy resins and polyols for coating, adhesive and composite omulations exhibiting ameliorated performance in water repellency, anti-corrosion, and fast hardness development during cure.Type: GrantFiled: November 25, 2015Date of Patent: October 24, 2017Assignee: CARDOLITE CORPORATIONInventors: Mauricio Pinto, Hong Xu, Anbazhagan Natesh, Junhong Wei

Patent number: 8410237Abstract: Cardanol based dimers are provided. The cardanol dimers are formed by hydrosylylation with silanes. Cardanol based dimers may be further reacted to form epoxy curing agents and epoxies which can be used as anti-fouling coatings on ship hulls and marine structures. The cardanol dimers may also be used to produce friction particles or phenolic resins. Methods of synthesizing the cardanol based dimers, the epoxy curing agents and the epoxies are also provided.Type: GrantFiled: November 17, 2010Date of Patent: April 2, 2013Assignee: Cardolite CorporationInventors: Zhisheng Dai, Adarsh Dalal, Donald C. Lawson, III, Jinbao He

Patent number: 6229054Abstract: The present invention comprises a process for the hydroxyalkylation of cardanol with cyclic organic carbonates in the presence of organic or inorganic catalysts and a novel composition of matter produced by that process. The unique molecular structure of cardanol allows the use of a variety of organic or inorganic basic catalysts, including triethylamine, imidazol, sodium hydroxide and sodium carbonate, in the hydroxyalkylation reaction without forming quantities of undesirable side-products. According to this invention, the final product, monohydroxyalkylcardanyl ether, can be obtained with high yield and high purity. The product has a light color and its color stability is enhanced by replacing the phenol's hydroxyl group with a more stable hydroxyalkoxyl group.Type: GrantFiled: December 9, 1999Date of Patent: May 8, 2001Assignee: Cardolite CorporationInventors: Zhisheng Dai, Meng J.
