摘要： A foundry mix includes a major amount of a foundry aggregate and an effective binding amount of a binder system. The foundry binder system cures in the presence of sulfur dioxide and a free radical initiator. The binder system may include (1) 10 to 70 parts by weight of an epoxy novolac resin; (2) 0.5 to 10 parts by weight of resorcinol; (3) 20 to 70 parts by weight of a monomeric or polymeric acrylate; and (4) an effective amount of a free radical initiator. Notably, (1), (2), (3) and (4) are separate components or mixed with another of said components, provided (4) is not mixed with (3) until a foundry mix is to be created, where said parts by weight are based upon 100 parts of the binder system.

摘要： This invention discloses a transparent standalone resin or masterbatch concentrate composition and manufacturing method of transforming commercial transparent grade base thermoplastics into anti-biofouling resins through extrusion or any similar hot melt mixing processes. The re-compound solids enable a number of product reforming processes, including but not limited to thermoforming, profile extrusion, injection molding, blow molding, blow filming, film casting, and spinning into articles of different shapes and geometries or overmolding on plastic substrates that can resist surface adsorption of microbes, mammalian cells, proteins, peptides, nucleic acids, steroids and other cellular constituents after solidification. The articles formed thereof additionally exhibit mechanical reinforcement and no leaching while retain the optical clarity of the base thermoplastics in the same product form as quantified in terms of the light transmittance and haze.
