Patent number: 6811864Abstract: A synthetic material comprises a base material providing at least one tacky surface that is tacky at a temperature of less than about 80° C.; and a powder layered upon the base material which has a substantially non-tacky surface at a temperature of up to about 40° C. and exhibits adhesiveness at a temperature of greater than 120° C. The powder includes one or more correspondence components such as an epoxy resin which is either i) substantially identical to a component of the base material, or ii) the monomer or oligomer configuration of the correspondence component is substantially identical to a component of the base material but may have a greater molecular weight or longer polymer chain structure, or iii) is insubstatantially different from a component of the base material (e.g. has the same characteristics and a similar structure but a higher molecular weight).Type: GrantFiled: August 13, 2002Date of Patent: November 2, 2004Assignee: L&L Products, Inc.Inventors: Michael J. Czaplicki, Keith Madaus

Patent number: 6805969Abstract: Novel coating solutions are disclosed that promote desirable adhesion to substrates formed from nylon, polyester, or a combination thereof. These coating solutions include nylons having specific solubility together with select formaldehyde resins and resin mixtures. The solutions provide superior adhesion and are therefore attractive to thread applications as well as formed structures.Type: GrantFiled: March 13, 2002Date of Patent: October 19, 2004Assignee: E. I. du Pont de Nemours and CompanyInventor: Rolando Umali Pagilagan
