Resin binder

The limited tractability of the polymer makes processing in conventional plastics form very difficult. Nevertheless the materials have been used in the manufacture of seals, gaskets and piston rings (Vespel-Du Pont) and also as the binder resin for diamond grinding wheels. 

The thermosetting materials are said to be initially linear but are cross-linked by heating in air to a temperature of at least 345°C. It is claimed that they have a useful working range up to 315°C. The materials may be used in compression mouldings powders, as the binder resin in glass cloth laminates and as the polymer base in heat-resistant metal coatings. 

In industrial outlets the inks are often based on solvents such as alcohols and ketones containing the binder resins reqnired for the adherence of the colour to a particular substrate, whether this be paper, card, plastic or metal. 

The DnPont photopolymeric system consists of polymeric binder resins, e.g. PVA, PMMA, cellnlose acetates and styrene-acrylates, reactive acrylic monomers, e.g. aryloxy or alkoxy acrylates, a dye sensitiser and a radical or charge transfer photoinitiator, e.g. DEAW and HABI respectively (see Chapter 4, section 4.5.2), and plasticisers. The process for producing the refractive index structures is as follows ... 

One of the Russian igniter compounds contained Ba02 60.0, Mg 13.6, binder (resin) 26.4% 0.65g was used for each 76mm APHE shell (Ref 2)... 

COCs have been used as binder resins in toners to replace the conventional binders, such as styrene/acrylate resins and poly(ester) resins (53,55). 

Several groups have investigated three-component systems encompassing both chemical amplification and dissolution inhibition. As stated earlier, Smith and Bonham (63) reported resist materials composed of a binder resin (novolac), a nonpolymeric compound containing acid-labile functional groups such as acetals, and a trihalomethyl-substituted 5-triazine acid photogenerator. The acid-labile compound acts as a novolac dissolution inhibitor in a manner analogous to the action of DNQ in conventional positive resists. However, in this case, the inhibitor is not photochemically active. Instead,... 

Traditionally the inks were based on organic solvents, comprising solutions of binder resins such as vinyl chloride polymers, vinyl chloride-acetate copolymers and acrylics in toluene/methyl ethyl ketone or ethanol/ethyl acetate— pigments, flattening agents, waxes, and other substances being added as required to enhance performance. More recently, because of the desire to... 

The coated ciystal is cured in a drying oven of 160 °C for an hour to make the particles bound on the surface. An SEM photograph of the crystal is exhibited in Fig. 1. In the figure, dark particles are binder resin and grayish particles are molecular sieve. At lower left comer there is a large particle of molecuW sieve and resin bound. 

Hydrocarbon solvents are the most commonly used solvents in paints to carry the pigment and binder. They are divided into three groups aliphatic, naphthenic, and aromatic. The preferred type of solvent is an odorless aliphatic hydrocarbon (mineral spirits), which can be used in all areas including home. However, mineral spirits do not dissolve all binder resins. Aromatic solvents provide stronger solvency, but with a greater odor. The most common are toluene, xylene, and naphthas. 

Bonded insulating materials, e.g. sheets or rolls, are manufactured by spraying a binder resin, generally phenol/formaldehyde, onto the fibers and hardening under compaction in a tunnel kiln... 

Acid-catalyzed condensation has been the primary and dominant foundation for aqueous base developable negative resist systems [354-363]. The first commercial chemical amplification resist was built on this mechanism. The condensation resists are typically three-component systems comprising a base soluble binder resin bearing reaction sites for crosslinking (phenolic resin), a radiation-sensitive acid generator, and an acid-sensitive latent electrophile...
