A requirement for external closure coatings is low discoloration when it is subjected to phenolic fumes. Closures traditionally have a phenolic containing internal lacquer. This is normally applied after the external decoration. Dining the prolonged stoving of the internal lacquer, phenolic fumes are generated and may cause discoloration. The application of the internal lacquer before external decoration minimises this problem. However, the practice of applying internal lacquers as the final coat is considered to... 

Types of internal enamel for food containers include oleoresins, vinyl, acryflc, phenoHc, and epoxy—phenoHc. Historically can lacquers were based on oleoresinous products. PhenoHc resins have limited flexibiHty and high bake requirements, but are used on three-piece cans where flexibiHty is not required. Vinyl coatings are based on copolymers of vinyl chloride and vinyl acetate dissolved in ketonic solvents. These can be blended with alkyd, epoxy, and phenoHc resins to enhance performance. FlexibiHty allows them to be used for caps and closures as weU as drawn cans. Their principal disadvantage is high sensitivity to heat and retorting processes this restricts their appHcation to cans which are hot filled, and to beer and beverage products. 

The seam closure on a folding carton is typicahy made using a latex, poly(vinyl acetate), vinyl acetate copolymer, or hot-melt adhesive (27). The choice of adhesive depends on a number of factors, including the nature of any coating used on the package and the production speeds required. 

Specifications and Standards Test Methods. Ethylcellulose is cleared foi many apphcations in food and food contact under the Eedeial Eood, Dmg, and Cosmetic Act, as amended. Examples include binder in dry vitamin preparations for animal feed, coatings and inks for paper and paperboard products used in food packaging, and closures with sealing gaskets for food containers (44). Methods of analyses ate given in ASTM D914-72 (19), NationalFonmila XIV, and Food Chemicals Codex II. 

Closure liners of pulpboard or cork, unless specially treated with a preservative, foil or wax coating, are often a source of mould contamination for liquid or semi-solid products. A closure with a plastic flowed-in linear is less prone to introduce or support microbial growth than one stuck in with an adhesive, particularly if the latter is based on a natural product such as casein. If required, closures can be sterilized by either formaldehyde or ethylene oxide gas. 

Percutaneous coronary intervention A minimally invasive procedure whereby access to the coronary arteries is obtained through the femoral artery up the aorta to the coronary os. Contrast media is used to visualize the coronary artery stenosis using a coronary angiogram. A guidewire is used to cross the stenosis and a small balloon is inflated and/or stent is deployed to break up atherosclerotic plaque and restore coronary artery blood flow. The stent is left in place to prevent acute closure and restenosis of the coronary artery. Newer stents are coated with antiproliferative drugs, such as paclitaxel and sirolimus, which further reduce the risk of restenosis of the coronary artery.

Butyl acetate [123-86-4], one of the more important derivatives of -butyl alcohol produced commercially, is employed as a solvent in rapid drying paints and coatings. In some instances, butyl acetate, C.H1202, has replaced ethoxyethyl acetate [111-15-9] due to the latter s reported toxicity and teratogenicity. Butyl acetate is used in leather treatment, perfumes, and as a process or reaction solvent and is also used extensively with wood coatings, maintenance coatings, and in coatings for containers and closures. 

Having sold all these base chemicals - most of them at peak value - UCB focused on innovative specialty resins such as UV cure resins, powder coating resins, and high-solid resins for automotive, graphic arts, and industrial applications. At the end of 2004, just before the closure of the sale to Cytec and two years after the acquisition of the Solutia activities, UCB s chemicals activity had a turnover of EUR 1.1 billion, around 40 percent of which was outside Europe, an EBITDA of EUR 147 million, and a leading position in most of its markets. 

Electron microscopic pictures taken during phase 2 show an increased number of clathrin-coated D-shaped plasma membrane invaginations, which were initially attributed to synaptic vesicle caught in the process of fusion with the presynaptic membrane (Abe et al. 1976 Chen and Lee 1970), but later studies interpreted them as incomplete endocytosis of SV (Dixon and Harris 1999 Harris et al. 2000). We have suggested that SPAN halts endocytosis at its very last step, the fission of the vesicle from the plasma membrane which requires the neck closure, i.e., exactly the reverse process of membrane fusion (Montecucco and Rossetto 2000 Rossetto et al. 2006). 

PTT is used in apparel, upholstery, specialty resins, and other applications in which properties such as softness, comfort stretch and recovery, dyeability, and easy care are desired. The properties of PTT surpass nylon and PET in fiber applications, and polybutylene terephthalate and PET in resin applications such as sealable closures, connectors, extrusion coatings, and blister packs (14).
