Resins chlorination

Nitrile rubber is compatible with phenol-formaldehyde resins, resorcinol-formaldehyde resins, vinyl chloride resins, alkyd resins, coumarone-indene resins, chlorinated rubber, epoxies and other resins, forming compositions which can be cured providing excellent adhesives of high strength, high oil resistance and high resilience. On the other hand, NBR adhesives are compatible with polar adherends such as fibres, textiles, paper and wood. Specific formulations of NBR adhesives can be found in [12]. 

Atmospheres polluted by oxidising agents, e.g. ozone, chlorine, peroxide, etc. whose great destructive power is in direct proportion to the temperature, are also encountered. Sulphuric acid, formed by sulphur dioxide pollution, will accelerate the breakdown of paint, particularly oil-based films. Paint media resistant both to acids, depending on concentration and temperature, and oxidation include those containing bitumen, acrylic resins, chlorinated or cyclised rubber, epoxy and polyurethane/coal tar combinations, phenolic resins and p.v.c.

Lead powder can be combined with many binders [5.165], [5.166], It does not affect the stability or viscosity of the paint. Binders that absorb only small amounts of water are particularly suitable (e.g., epoxy resins, chlorinated rubber). When formulating paints based on lead powder, care must be taken not to dilute it with other pigments and extenders by more than 5 vol%. 

In 1942, various materials, such as resinous chlorinated paraffin, chlorinated rubber, chlorinated alkyd resins, and vinyl and vinylidene resins were unavailable for use in fire-retardant paints. Such chlorinated binders as were available were in critical demand for flameproofing fabrics. The present availability of such materials... 

Additive flame-retardant compounds include brominated epoxy resins, chlorinated hydrocarbons, decabromodiphenyl ether, and pentabromodiphenyl ether. Where transparency is not important, antimony oxide can be used as a synergist to reduce the amount of halogen required. 

Organic zinc-rich primers are based on epoxy/polyamides, high-molecular-weight linear epoxies, moisture-cured urethanes, high-styrene resins, chlorinated rubbers and epoxy esters. In this type of primer zinc is covered with a monomolecular layer of the binder which facilitates the adhesion of the film to the substrate. 

Other uses for alkyds are in general industrial coatings such as machinery and metal furniture. Alkyd resin-chlorinated rubber based coatings are used in traffic paints, but use is declining because of VOC concerns. Some alkyds are still used in refinish paints for automobiles. Uralkyds are used as a vehicle for urethane varnishes for the do-it-yourself market. 

With the introduction of low total chloride epoxy resins (chlorine content <700 ppm), the wire bond failure due to the chlorine impurities in the resin has become much less prominent than that due to the bromine from the fire retardant additives in the molding compound. The chlorine content in a typical molding compound is less than 150 ppm while the bromine content is 0.75-1.25% (12,500 ppm). A release of bromine upon heating from resin, as experienced above, certainly will have a great detrimental effect on device reliability.

Dover Chemical Corporation produces resinous chlorinated paraffins under a name Chlorez . All Chlorez grades have a physical form of white powder (particles smaller than 50 mesh) with chlorine content around 70%. The manufacturer recommends Chlorez as flame retardants (in a combination with antimony trioxide) and lately as a nonreactive coupling agent under a brand name Doverbond (such as Doverbond DB 4300 or Doverbond 3000). The manufacturer claims that Chlorez in the amount of 10% along with 3% of a lubricant in the WPC shows an effect of a coupling agent and increases the flexural strength and modulus of the product, as well as the UV and moisture resistance (private communication, Dover Chemical Corp.). DB 4300 lists at 1.50/lb [12,13].

Phenolic compounds sulfonate very easily. Phenol reacts to the extent of 94 per cent when heated with an equimolar quantity of concentrated acid for 2 hr at 100 C. The cresols react less completely with considerable variation in isomers. These phenolic sulfonates find application for preparing tanning agents and ion-exchange resins. Chlorinated phenols are sulfonated in the preparation of dye intermediates. ...

White spirit is used predominantly in the paint industry as a solvent or diluent for oil-based, alkyd resin, chlorinated rubber, and some vinyl chloride copolymer paints light napththas have flash points above 21 "C. Varnish makers and painters (VMP) naphtha (hp 100-150 "C) is used mainly as diluent. 

Cyclohexanone [108-94-1] (Hexanone) is insoluble in water, miscible with organic solvents. It is a high boiler with very good solvency for cellulose nitrate, cellulose ethers and esters, colophony, shellac, alkyd resins, natural and synthetic resins, chlorinated rubber, rubber, vinyl polymers and copolymers, polystyrene, ketone and ketone-formaldehyde resins, fats, oils, waxes, blown oils, and bitumen.

Ethyl triglycol [112-50-5] [2-(2-ethoxyethoxy)ethoxy]ethanol, triethylene glycol monoethyl ether] is an almost colorless, neutral, mild-smelling liquid with a low hygroscopicity. It is soluble in water and most organic solvents, but is only partially miscible with aromatic and aliphatic hydrocarbons. Ethyl triglycol dissolves cellulose nitrate, shellac, colophony, ketone resins, maleate resins, chlorinated rubber, alkyd resins, and many other paint resins. It does not dissolve cellulose acetate, poly(vinyl chloride), vinyl chloride copolymers, fats, oils, and rubber. 

Nitropropane [ 79-46-9] is a colorless, nonhygroscopic liquid with a mild odor. It dissolves cellulose nitrate, cellulose ethers, alkyd resins, chlorinated rubber, poly(vinyl acetate), vinyl chloride copolymers. Poly(vinyl chloride), colophony, polyacrylonitrile, waxes, rubber, and shellac are insoluble. It is used as a cosolvent in paints to improve pigment wetting, flow properties, and electrostatic processing it also reduces the paint drying time. 2-Nitropropane is classified as carcinogenic.
