Disclosed are UV-cured heat transfer labels prepared from a mixture containing at least one thermoplastic resin, at least one material for solvating the thermoplastic resin, the solvating material being either a solvent or liquid monomer, and at least one photo-initiable material which initiates curing of the composition.

U-V cured heat activated labels for substrates and preparation methods

A porous plate used in a fuel cell is sealed with an essentially 100% active material and catalyst mixture. The mixture is absorbed into and fills essentially the entire void volume provided by the pores. The mixture is then thermally shocked to partially cure the mixture thereby preventing wicking. The partially cured mixture is then post cured by elevating the temperature such that the catalyst initiates free radical polymerization. Since the sealant is essentially 100% active, there are no escape paths formed during the curing process, and the final seal is essentially 100% leak proof.

A continuous, pinhole-free thermoplastic polymer coating, which may be a fluoroelastomer, is applied to a porous metal surface in a single coating step by spraying the thermoplastic polymer from a thermal spray gun onto a porous metal surface which is at substantially room temperature to form a semi-fused, highly porous coating. The porous metal surface is then heated to fuse the thermoplastic polymer coating into a well-anchored, continuous film. This method permits the application of a continuous thermoplastic polymer coating with one coating step rather than with the plurality of coating steps currently needed to produce a coating with comparable properties.

Method of applying a continuous thermoplastic coating with one coating

A non-combustible, inorganic heat insulation which can be sprayed onto a surface being insulated is particularly useful for forming the cold face insulation layer in a catalytic reformer housing. The insulation is formed from an inorganic cement having glass and/or ceramic microspheres mixed therein.

Catalytic reformer housing insulation and method of making same

A seal material having improved sealing characteristics and useful in high temperature, corrosive environments, particularly fuel cells is disclosed. The material comprises an acid resistant, high temperature stable fluorinated elastomer and a blowing agent which activate at a temperature within the range of curing temperatures of the elastomer. Improved sealing characteristics due to volume expansion of the seal material applied and activated within the fuel cell were observed. The process of activating the seal material at the operating temperature of the fuel cell is also disclosed. The invention also discloses the process of using the seal material within a fuel cell.
