Ethyl methacrylate polymer
Paraloid B-72 is an excellent general purpose acrylic resin. It can be applied in either clear or pigmented coatings by a variety of application methods.
Paraloid B-72 is an excellent general purpose acrylic resin, supplied as a 100 % solid grade or as a 15 %
solution. It can be applied in either clear or pigmented coatings by a variety of application methods and can be air-dried or baked.
Paraloid B-72 has a very low reactivity with sensitive phosphorescent and luminescent pigments. The durability and non-yellowing characteristics also make it valuable for use with these pigments.
Paraloid B-72 is compatible with other film forming materials such as vinyls, cellulosics, chlorinated rubbers, and silicones and can be used in combination with them to produce coatings with a wide variety of characteristics.
Paraloid B-72 is very resistant against water, alkalis, acids, oils and chemical fumes. The coverings are very elastic and adhere on many different surfaces, e.g. also on light metals.
Paraloid B-72 is unique in possessing a high tolerance for ethanol. The property allows its use in applications in which strong solvents cannot be tolerated. The alcohol dispersions may be cloudy or milky; however, clear, coherent films are formed.
Paraloid B-72 is an acrylic resin with a high molar mass, thus, it doesn ́t have a defined melting point. It starts to melt at 70 - 75°C; the flowing point is at 145 - 150°C. TG: 40°C
