The composition can include an emulsion comprising one or more pitches, one or more fatty acids, one or more rosins, or any combination thereof. The composition can also include one or more film forming polymers, one or more oils, or a combination thereof.
Claims20
A composition, comprising:
- an emulsion comprising a pitch, fatty acids, rosin acids, or any combination thereof, and about 30 wt % to about 90 wt % water, based on the total weight of the emulsion;
- and
- a film forming polymer comprising a copolymer of styrene and maleic anhydride, a copolymer of styrene and maleic acid, or a combination thereof.
A composition, comprising:
- an emulsion comprising a tall oil pitch, a crude tall oil, distilled tall oil, tall oil rosin acids, tall oil fatty acids, or any combination thereof, and about 30 wt % to about 90 wt % water, based on the total weight of the emulsion;
- and
- a film forming polymer comprising a copolymer of styrene and maleic anhydride, a copolymer of styrene and maleic acid, or a combination thereof.
A composition, comprising:
- an emulsion comprising a pitch;
- and
- a film forming polymer comprising a copolymer of styrene and maleic anhydride, a copolymer of styrene and maleic acid, or a combination thereof, wherein a concentration of the film forming polymer is about 5 wt % to about 50 wt % based on the weight of the pitch.
