The final question concerned the predicted thermal storage lifetime of the coating, which would probably be a good measure of stability lifetime of the hot-melt-coated particle. As shown in Fig. 4.28, the coating mixture was predicted to be thermally stable in dry air at 40°C for more than four years. [Pg.114]

Hydrocarbon resins comprise a range of low-molecular-weight products (M < 3000) used as adhesives, hot-melt coatings, tackifying agents, inks, and additives in rubber. These include products based on monomers derived from petroleum as well as plant sources. The petroleum-derived products include polymers produced from various alkenes, isoprene, piperylene, styrene, a-methylstyrene, vinyltuolene, and dicyclopentadiene. The plant-derived products include polyterpenes obtained by the polymerization of dipentene, limonene,... [Pg.411]

Hot-melt thermoplastic primary coatings for optical fibers have also been employed to a limited extent (26,27). They may be formulated with reasonably low glass transition temperatures, but particle contamination is a difficult quality control problem with these materials. UV-curable coating formulations have largely supplanted hot melt coatings owing to the increased draw speed which they offer. [Pg.415]

Styrene/isoprene/styrene (SIS) block copolymer (styrene isoprene ratio of 15/80 to 30/70 by weight) is a thermoplastic rubber. This copolymer can be changed into a good skin adhesive when it is mixed with tackifiers and oils. The advantage of this adhesive is that it can be coated with hot melt coating process... [Pg.2927]

It should be noted that the SIS block copolymer is unstable in high temperature (100-150°C) and oxygen because of the presence of a double bond in the poly-isoprene subunit. Hence, the addition of antioxidants such as butylhydroxytoluene is necessary in the hot melt coating process. In addition, heat stability is also required in manufacturing drugs. [Pg.2927]

With regard to coating processes, various fluidized-bed techniques and their modifications were evaluated for hot-melt coating.f ° The fluidized-bed techniques include the top, bottom, and the tangential spray or rotary fluidized-bed modes. The particles to be coated are suspended in a heated high-velocity air stream, and the molten wax is applied in the form of atomized liquid droplets. [Pg.4071]
