Coating cellulose lacquer

Front-silvered mirrors can be pohshed with optical rouge on a pad of chamois leather over cotton wool. Care is necessary because it is easy to polish completely through the silver. Back-silvered mirrors can be protected by first varnishing the silver and then painting the varnish. Front-silvered mirrors can be protected with a thin coat of lacquer, such as a dilute solution of cellulose nitrate in amyl acetate. The lacquer should not be too thin, or interference colours may be produced.

Both of the periods of linear temperature rise AT, and AT2 were used to calculate power (see Figure 8). The plots are normalized with respect to the maximum value using both periods and were shown to be very similar. Several different absorbing coatings were used glues (polystyrene cement and UHU), epoxy resins, silicone rubber, polyurethane varnish, and cellulose lacquer. The diameter and length of the beads were varied within the ranges 0.5-0.8 mm and 0.68-1 mm.

Wood furniture coatings usually contain urethane/isocyanates in addition to UF, volatile plasticisers, residual solvents and free monomers from incomplete polymerisation of the coating. Nitrocellulose lacquer, acrylic, cellulose acetate butyrate and polynrethane (with plasticisers like epoxy, di-bntyl phthalate, butyl benzyl phthalate and isopropyl myristate) are the coatings commonly nsed on clear finished wood furniture. In these, the amonnts and... 

Early types of coatings included silicone oils and rubbers, polyamideimide, cellulose lacquers and blocked urethanes. Hot melts have also been proposed n -1 . It proved to be difficult to overcome problems in handling, stability, durability and speed of application (drawing speeds of up to 10 m s are required). 

Over the next two decades extruded PVC with a lacquered, lapped rayon secondary coating for protection against soldering temperatures and for identification was the standard wire insulation. The jumper wire over this period was PVC-coated tinned copper wire with a cellulose lacquered rayon braid secondary coating containing a nonflammability additive. 

Uses. Diacetone alcohol is a widely used solvent in the coatings industry where it finds appHcation in hot lacquers which require high boiling components, and in bmshing lacquers where its mild odor, blush resistance, and flow-out properties are desired. Diacetone alcohol is also a solvent for nitrocellulose, cellulose acetate, and epoxy resins. 

Low viscosity cellulose acetate is used in lacquers and protective coatings for paper, metal, glass, and other substrates and as an adhesive for cellulose photographic film because of its quick bonding rate and excellent bond peel strength (135) (see Coatings). Heat-sensitive adhesives for textiles have also been prepared from cellulose acetate (136). Extmded cellulose acetate film makes an excellent base for transparent pressure-sensitive tape (137) (see Adhesives). 

Cellulose acetate butyrates with high butyryl content and low viscosity are soluble in inexpensive lacquer solvents. They are widely used in lacquers for protective and decorative coatings appHed to automobiles and wood furniture. 

Higher butyryl esters, formulated with acryUc polymers, provide coatings with excellent weather resistance, good colorfastness and dispersibiUty, and good flow properties (154). Formulations for a typical automotive refinishing lacquer and a wood furniture lacquer are given in Tables 12 and 13, respectively. Low viscosity, high butyryl cellulose esters tolerate substantial amounts of alcohol solvent without appreciable increase in solution viscosity. 

Uses. Cellulose nitrates with differing nitrogen contents have various appHcations (Table 3). The largest iadustrial use of CN is protective and decorative lacquer coatings. CN is soluble ia a variety of organic solvents and yields clear, tough films. CN is also compatible with many plasticizers and resias. 

The acetates of most alcohols are also commercially available and have diverse uses. Because of their high solvent power, ethyl, isopropyl, butyl, isobutyl, amyl, and isoamyl acetates are used in ceUulose nitrate and other lacquer-type coatings (see Cellulose, esters). Butyl and hexyl acetates are exceUent solvents for polyurethane coating systems (see Coatings Urethane polymers). Ethyl, isobutyl, amyl, and isoamyl acetates are frequentiy used as components in flavoring (see Flavors and spices), and isopropyl, benzyl, octyl, geranyl, linalyl, and methyl acetates are important additives in perfumes (qv). 

The ether is also used in paint, varnish and lacquer formulations. A recent development is the use of ethyl cellulose gel lacquers. These are permanent coatings applied in a similar way to the strippable coatings. They have been used in the United States for coating tool handles, door knobs and bowling pins. 

The predominant RO membranes used in water applications include cellulose polymers, thin film oomposites (TFCs) consisting of aromatic polyamides, and crosslinked polyetherurea. Cellulosic membranes are formed by immersion casting of 30 to 40 percent polymer lacquers on a web immersed in water. These lacquers include cellulose acetate, triacetate, and acetate-butyrate. TFCs are formed by interfacial polymerization that involves coating a microporous membrane substrate with an aqueous prepolymer solution and immersing in a water-immiscible solvent containing a reactant [Petersen, J. Memhr. Sol., 83, 81 (1993)]. The Dow FilmTec FT-30 membrane developed by Cadotte uses 1-3 diaminobenzene prepolymer crosslinked with 1-3 and 1-4 benzenedicarboxylic acid chlorides. These membranes have NaCl retention and water permeability claims.
