Paint and Coat : natural bitumen's applications in the bituminous paint, coatings and wood stain industries. It contains an outline which highlights natural bitumen's advantages in these markets, plus sample formulations, mixing instructions, and product performance data, etc. In the paint applications, natural bitumen is usually used in combination with bitumen (asphalt). In most cases, if natural bitumen is used alone, the final paint will be very hard and brittle after drying. If normal straight-run bitumen is used alone, the finished paint is too soft and tacky. Therefore, a combination of natural bitumen and bitumen is used to achieve the desired hardness (penetration) and drying time of the finished paint. In addition to imparting hardness to the paint, natural bitumen is also increasing the paint's- (1) adhesion; (2) gloss; (3) chemical resistance; (4) water resistance; and (5) body. For hardness, natural bitumen has a zero (0) penetration (at 25°C; 100 gm, 5 sec.) compared to the 60-70 pen, 80-100 pen or softer bitumens commonly available from petroleum companies or asphalt manufacturers. Approximately 90% of all bitumen is used for road construction and these hardness grades are acceptable for that purpose. However, they are too soft by themselves for the manufacture of paint and surface coatings which require hardness values around 5 penetration for acceptable paint drying. Paint films composed of bitumen alone are tacky if the penetration is more than 10, and are brittle if less than 4. Air-blowing soft, road paving bitumens down to 5 pen is a common practice but this is an advanced aging process which damages the bitumen. Air-blowing upsets the colloidal balance of the bitumen which can lead to films of oil or wax exuding from the bitumen. If these films exude to the surface of the paint, the result is a loss of gloss. If these films migrate to the interface of the substrate, the result is a loss of adhesion which causes the paint to peel. Other disadvantages of using air-blown bitumen in paint formulations include gelling with certain solvents and large viscosity increases during the mixing of the paints or during their storage. Therefore, rather than air-blowing a soft bitumen down to 5 penetration, that same soft bitumen may be transformed into a hard bitumen by modifying it with natural bitumen, avoiding the disadvantages of oil/wax migration and gelation. For example, adding about 35 to 50% mineral bitumen to an 80-100 penetration bitumen will transform it to 5-10 penetration, suitable for paint making.
Recommended Uses : For painting metal, masonry, and wood surfaces, inside and out where a corrosion resistance black protective coating is desired.
