As an example. Table 2 shows how Wacker core-shell particles are able to enhance the impact resistance at RT and -27 °C of an acrylic powder coating system by a factor of 2 - 3.

It was found that the reaction proceeds when n = 4 or 5 but not when n = 2 or 3. Difunctional macrocyclic urea amides were made by reacting the raacrocyclic urea with diacid chlorides such as isophthaloyl chloride. The utility of these cross-linkers was proven in solvent coatings, acrylic powder coatings, and electro-deposition coatings. 

Acrylics Powder, solutions Easily processed. Form strong films. Temperature range 200-250 F. Adaptable for paint or spray. Coatings. 

Siloxane containing polyester, poly(alkylene oxide) and polystyrene type copolymers have been used to improve the heat resistance, lubricity and flow properties of epoxy resin powder coatings 43). Thermally stable polyester-polysiloxane segmented copolymers have been shown to improve the flow, antifriction properties and scratch resistance of acrylic based auto repair lacquers 408). Organohydroxy-terminated siloxanes are also effective internal mold release agents in polyurethane reaction injection molding processes 409). 

Figure 10 shows the HPGPC traces of two different batches of in-house acrylic resins for powder coatings. It is seen that due to the presence of high levels of low molecular weight components...

Several benzimidazolone pigments are suitable candidates for use in powder coatings based on polyester, acrylic, or polyurethane resin. These pigments satisfy the heat requirements of this application and do not plate out in these media (Sec. 1.6.4.1). Various benzimidazolone pigments even meet the particularly high thermal standards of coil coating. These pigments are also suitable for use in architectural and emulsion paints. 

In practical application, most types of P.B.15 1 are completely fast to overcoating in oven drying systems. The pigments are suitable candidates for powder coatings, for instance for acrylate or polyurethane-based systems, in which they do not exhibit plate-out (Sec. 1.6.4.1). 

Uses. Production of polymethyl methacrylate polymers for use in acrylic sheet and acrylic molding, extrusion powder, acrylic surface coatings, printing inks, and adhesives used in surgery and dentistry... 

Solid urethane and polyester acrylates may be used as main components of radiation curable powders. Together with suitable unsaturated polyesters, powders are formed, which give low-film-flow temperatures and allow separating of film formation from curing. This technology has been used successfully in powder coating of wood and plastics. ... 

To be suitable for radiation-curable powder coatings, materials must contain unsaturated double bonds. They may contain acrylic or methacrylic unsaturations, but nonacrylate systems can also be used.32 The latter are based on the same chemistry... 

Binders for thermosetting powder coatings are often called a hardener. The hardeners are a mixture of a primary resin and a cross-linker. The major types of binders can be limited to polyester, epoxy, hybrid epoxypolyester, acrylic, and UV cure types. Polyester binders are used for good exterior durability, retention of gloss, and resistance to chalking.
