The pulverized cork is mixed with other papermaking materials and formed into a paper-made substrate. The paper-made substrate is impregnated with a synthetic resin to be a binder and heated and cured. The cork itself has a high friction coefficient ?. Moreover, a powder thereof increases surface area and area in contact with a separator plate of a counter member, thereby improving a friction coefficient of a friction surface of the wet friction member. The friction coefficient of the cork itself and capacities for absorbing and discharging oil are improved by heating the cork. Thus, there is provided a wet friction member that has a higher friction coefficient ?. An increase in the friction coefficient ?, weight reduction by reducing the number of friction members, and high efficiency are achieved when used as a wet friction member.

The resin is prepared by adding the poly(urethane) prepolymer solution at a controlled rate to the diamine in a organic solvent which allows a resin solution to be formed, which may be used in the formulation of laminating printing ink and coating compositions without the need for adjuvants, grinding in polyvinyl butyral or blending with nitrocellulose base.

  • Patent number: 6649683
    Abstract: A method of forming a solid matrix for use with surface-enhanced Raman spectroscopy is described. The method comprises the steps of: admixing a colloidal metal solution with a polymeric support medium to form a suspension; optionally depositing said suspension on a surface; and then drying the suspension to form the matrix. The polymeric support medium provides a plymer/sol suspension in which the sol particles are resistant to aggregation and precipitation. Upon drying the suspension shrinks to provide a mechanically-hard film subsequently usable to provide a sample for spectroscopic analysis.
