Waterborne Autoweldable Shop Primer

A one-part, storage-stable, air-dryable, latex-coatable waterborne film-forming coating composition has dispersed therein sufficient conductive material to provide an autoweldable hardened shop primer layer when applied to metal components. The thus-primed components may be welded together using automated arc welding equipment without having to remove the coating composition at the weld site. The conductive material desirably causes little or no airborne emission of unsafe quantities of heavy metals or other harmful substances when the primer is volatilized or combusted during welding.

Resin composition, prepreg, laminate, and printed wiring board

A resin composition containing a cyclic epoxy-modified silicone compound (A) represented by formula (1), a cyanic acid ester compound (B) and/or a phenol resin (C) and an inorganic filler (D): ##STR00001##

Non-fouling, anti-microbial, anti-thrombogenic graft—from compositions

Substrates, optionally coated with an undercoating layer, having grafted there from one or more non-fouling materials are described herein. The non-fouling, polymeric material can be grafted from a variety of substrate materials, particularly polymeric substrates and/or polymeric undercoating layers. The graft-from techniques described herein can result in higher surface densities of the non-fouling material relative to graft-to formulations. Graft-from methods can be used to produce covalently tethered polymers. The compositions described herein are highly resistant protein absorption, particularly in complex media and retain a high degree of non-fouling activity over long periods of time. The compositions described herein may also demonstrate antimicrobial and/or anti-thrombogenic activity. The non-fouling material can be grafted from the substrate, or optionally from an undercoating layer on the substrate, preferably without significantly affecting the mechanical and/or physical properties of the substrate material.
