5 They are not attacked at normal temperatures by dilute alkalies or mineralacids, alcohols, greases, oils, or aliphatic have a low moisture-vapor transmission rate, loworder of water absorption, and are tough and molecular weight and the ratio of vinyl chloride to vinyl acetate affect the solubility and other physicalproperties of the resin. As the molecular weight (degree of polymerization) is increased, the solution viscosityincreases and the strength of the film increases. Vinylchloride contributes film strength and toughness, as wellas water and chemical resistance. Vinyl acetate improvessolubility and film properly pigmented, coatings based on vinyl chloride/acetate copolymers have excellent outdoor durability.

6 Hydroxyl-modification improves compatibilityand adhesion, and provides a site for modification permits formulation of coatingsthat will adhere to clean metal surfaces on air-dry. Epoxy modification provides the ability to crosslink withcarboxyl-modified vinyl resins to give an all-vinyl reactivesystem that yields thermoset-like characteristics, mostnotably improved toughness, enhanced physical properties, and superior chemical Solution Vinyl Resins, produced by a proprietarysolution polymerization process, offer several advantages:High PurityNo water-soluble suspending agents or surfactants areused in the manufacture; therefore, water resistance isoutstanding.

7 Additionally, the as-received vinyl chloridemonomer (VCM) content of dry vinyl powders is <10 ppb(parts per billion). In formulated coatings, the VCM level is below the detectable limit of Polymer Composition and NarrowMolecular Weight DistributionProvide predictable solution viscosities and batch-to-batchproduction in GelsEasily dissolved and low in gels and insoluble UCAR Solution Vinyl Resins are completely compatiblewith each other and many different types of dry by evaporation.
