    Abstract: A waterborne paint for traffic marking contains as an emulsion binder, a support polymer formed of styrene and acrylic acid monomers and having an acid value of between about 50 and about 250 and a hydrophobic emulsion polymer comprised of acrylic ester monomers and optionally including styrene monomers. The support polymer, in aqueous ammonia solution, acts as a surfactant, maintaining the emulsion polymer within micelles. Paints in accordance with the invention contain between about 10 and about 15 wt. percent of the emulsion polymer, between about 60 and about 75 wt. percent fillers or pigments and between about 9 and about 18 wt. percent water. Due to the high solids loading and low water content, the waterborne traffic marking paint is fast drying. Colored paints prefereably utilize banded pigments.

  • Patent number: 5314943
    Abstract: A low viscosity, fast-curing binder for textile substrates is produced by admixing an aqueous emulsion copolymer latex with an aqueous solution copolymer formed by the copolymerization of an olefinically unsaturated polycarboxylic acid and an olefinically unsaturated monocarboxylic acid. Viscosities in the range of about 2 cps at 25% total solids to about 1000 cps at 35% total solids are realized by using solution copolymers containing about 40%-75% by weight of polycarboxylic acid.

  • Patent number: 5310802
    Abstract: An elastomeric composition comprising a major proportion by weight of a rubber comprising a halobutyl rubber (e.g. 75 to 95%) and a minor proportion by weight (e.g. 5 to 25%) of a copolymer of an olefin, e.g. ethylene, and an unsaturated carboxylic acid e.g. acrylic acid. This composition may be covulcanised with a general purpose rubber e.g. natural rubber, to which it has adequate adhesion. Thus a natural rubber tyre carcass may be covulcanised with a tyre inner liner formed of this composition.

  • Patent number: 5306744
    Abstract: An aqueous, radiation-curable, functionalized latex polymer composition and its preparation are disclosed. The composition is a multistaged latex polymer formed from a first stage polymer and a second stage polymer having .alpha., .beta.-unsaturated carbonyl functionalization which permits curing by UV radiation. The composition dries tack-free before curing. The final cured UV coating has excellent solvent resistance, water resistance, stain resistance, direct impact resistance and hot print resistance. The composition is useful in coatings, adhesives, inks and leather coatings, and is particularly useful as a coating on wood.
