Magnetic, conformable articles for use with traffic bearing surfaces are disclosed which comprise an organic binder having magnetic particles distributed therein. The articles may be employed in intelligent vehicle guidance systems, and in systems to guide other mobile objects such as farm animals, pets, or visually impaired pedestrians. Methods of making the articles and methods of using the systems to control and/or guide a mobile object using the magnetic field generated from the articles are also described.

A class of substituted urethane acrylates and methacrylates having an aliphatic backbone is provided, the members of the class having at least one ether or polyether group with at least one pendent fluorinated organic group attached thereto. The novel compositions may be radiation polymerized, e.g., by electron beam, actinic light or heat, to a light transmissive material which is well suited to optical application, such as coupling optical fibers and light emitting diodes so as to transmit light therebetween.

Curable substituted urethane acrylates

Microcapsules with liquid fills containing Lewis acid catalysts, catalyst concentrates comprising slurries of the microcapsules in liquid media, and a method for preparing the microcapsules and concentrates. The catalyst concentrates of the present invention are storage stable both alone and when incorporated in a one-part epoxy formulation.

Latent Lewis acid catalyst encapsulated within polymerized

A liquid composition useful for minimizing corrosion of aluminum surfaces comprising ethylene glycol or propylene glycol and fluoroaliphaticsulfonamidophosphonic acid or the salt thereof.

Corrosion inhibiting heat transfer liquid

Storage-stable, one-part, curable resin systems containing a latent Lewis acid catalyst which can be activated by applying mechanical force to the system.

Mechanically activateable one-part liquid resin systems

Storage-stable, one-part, curable resin compositions comprising I. a latent catalyst which comprises rupturable microcapsules having shell walls of a crosslinked interfacial polyurethane-polyether reaction product and liquid fills of a Lewis acid-glycerol complex, II. a cationically curable monomer composition and III. a Lewis base scavenger.

Heat activatable one-part liquid resin systems

Microcapsules with liquid fills containing Lewis acid catalysts, catalyst concentrates comprising slurries of the microcapsules in liquid media and a method for preparing the microcapsules and concentrates.

Latent Lewis acid catalyst system and process

Curable expoy resin-polyisocyanate systems which incorporate a minor amount of a cationically polymerizable, ethylenically unsaturated monomer and which are catalyzed by a Lewis acid.

Modified epoxy resin-polyisocyanate resin system

The surfaces of articles made of aluminum, such as annodized aluminum and bare aluminum, are treated with N-alkyl-fluoroaliphaticsulfonamidophosphonic acids or salts thereof to impart corrosion resistance to said surfaces.
