Boat varnish

Synthetic resins are extensively used, e.g., in surface finishes, in the fabrication and repair of boat and motor vehicle bodies, in the manufacture of laminated boards, for electrical components, in pattern making and in paints and varnishes. Non-rubber adhesives made from fish glues and from cotton derivatives (e.g. cellulose acetate) tend not to be sensitizing but, depending upon composition and the manner of use, many other types may pose significant dermatitic and fume hazards. 

Uses. About 60% of the MA produced is used to make unsaturated polyester and aikyd resins, which are formed by reaction of MA with glycols. Polyester resins are used in the fabrication of glass fiber reinforced parts. Applications include boat hulls, automobile body parts, patio furniture, shower stalls, and pipe. Aikyd resins are mostly used in coatings (paint, varnish, lacquers, and enamels). MA also is widely used as a chemical intermediate in the manufacture of plasticizers and dibasic acids (fumaric, maleic, and succinic). About 15% of MA production goes into the manufacture of viscosity index improvers and dispersants used as additives in lube oils. Several agricultural chemicals are based on maleic anhydride, the best known being Malathion. 

The bulk of polyester production in the United States has gone to the synthetic coatings field in the manufacture of glyptal resin coatings and varnishes, with production between 200,000,000 and 300,000,000 pounds in the postwar years. A recent development has been the use of polyester-styrene copolymers reinforced by Fiberglas for the manufacture of items such as low-pressure molded boats, corrugated structural sheet, and plastic pipe. The 1947 requirements for glycerol in the production of polyester resins and... 

An apparatus similar to that described for the preparation of SFs (p. 169) is used for the fluorination of pulverized electrolytic Cr or CrClg contained in a fluorspar or small alumina vessel. The fluorination temperature is 350-500°C. Some CrF, as well as most of the CrFs, migrates into the receiver. The main portion of the CrF4 is deposited in the reaction tube beyond the boat in varnish-like, glittering brown beads. When the fluorination is complete, the apparatus is flushed out with Ng or CO and the CrF4 is immediately sealed o in glass ampoules. 

The main outlets for urethane oils and alkyds are in varnishes for floors, boats and general use in undercoats and in industrial maintenance finishes (where gloss retention is less important than long-lasting film integrity and resistance to water and chemicals). 

Has anyone in the household removed paint or varnish while in the dwelling (includes paint removal from woodwork, furniture, cars, bicycles, boats)... 

Paints, varnishes (acid-proof enamel, acid-resistant coatings, anti-oxidants and solvents, boat deck sealing compound, lacquers)... 

Uralkyds are one of the most commonly used polyurethane resin, finding particular application in varnishes for floors, boats and general use. While these resins do not impart the best gloss, they do give excellent abrasion resistance and reportedly better water and alkali resistance than an alkyd. 

By midnineteenth century, iron boats began to displace wooden boats. This prompted naval stores producers to separate turpentine from oleoresin to meet the growing demand for a paint and varnish solvent. In the 20th century, the demand for rosin in paint and varnish was so great that its production reached 8.7 million pounds in 1900 and over 10 million pounds in 1910, the highest in the history of gum naval stores. Then wood rosin dominated the...
