Paints

 

Paints are any pigmented liquid, liquefiable, or solid mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors and in many different mediums, such as watercolor or synthetic. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid.

 

Most paints are either oilbased or waterbased and each has distinct characteristics. For one, it is illegal in most municipalities to discard oilbased paint down household drains or sewers. Clean up solvents are also different for waterbased paint than they are for oilbased paint. Waterbased paints and oilbased paints will cure differently based on the outside ambient temperature of the object being painted (such as a house.) Usually the object being painted must be over 10 °C (50 °F), although some manufacturers of external paints / primers claim they can be applied when temperatures are as low as 2 °C (35 °F).

 

In the paint industry, Gilsonite is utilized in a wide range of applications. Gilsonite is applied in this segment as weatherproofing paint bonding and faderesisting stain pigments. It is also an economical approach as well. The application is widely considered for Bitumenbased paints which are commonly used in car manufacturing industry. Adding Gilsonite improves UV resistance and general chemical resistance. Such usage has also made Gilsonite a common additive in wood stains and pipe coatings during the past years. Gilsonite has been used in the paint industry for many years. It is used in paints in which the Bitumen forms the basis of color. The high Nitrogen (N) content of Gilsonite increases the adhesion and stability of ultraviolet light.

 

 

This product is most commonly used to cover external surfaces, as well as acid resistance, car cover, and metal structure coatings.

Gilsonite in Paint:

 

Gilsonite in Paints has the ability to increase the hardness and adhesion. In general, the use of bituminous paints is a wellknown and common method, in particular for those paintings which need to withstand harsh weather conditions and/or are subjective to corrosion. This mineral can be added to asphalt base paints as a modifier, removing roughness and increasing paint gloss. In fact, bitumenbased paints have low quality, but by adding Gilsonite, the properties of the paint can be improved. This is because Gilsonite retains the properties of bitumen and spreads properly on any surface. The use of Gilsonite in paint results in excellent bonding with almost any material as a protective coating paint. It is known in the paint industry as a relatively less expensive additive than similarly functional additives.

Gilsonite in Paints for Automotive: 

 

Gilsonite paints are used in the automotive industry as a chassis coating and coating of metal structures due to its UV resistance. This material can give useful properties to paint and coating. As this mineral is both abrasive and chemically neutral, it has a high resistance to acids, water and chemicals. Thus it can be used in car radiators and waterproof coatings. By changing the colloidal balance and removing oil and wax from the bitumen, its properties change. If these oils and waxes come to the surface, the gloss of the coating will decrease, and if these oils and waxes go to the inner surface of the coating, the adhesion of the coating will decrease. There are several formulas for these coatings that can be used for a variety of applications. High nitrogen content and natural asphalt properties create adhesion in Gilsonite. This feature makes it possible to use these paints in the protection of materials as anticorrosion coatings and protective coatings against moisture. 

 

A special type of Gilsonite is also used in the manufacture of asphalt black paints and polished oils. It can also be used to make a blackbrown colored solution that is used in the bitumen coating of gas and sewage pipes.

Gilsonite in Wood Stains:

 

The application of Gilsonite in wood stains is to produce adhesive and coating for wood surface. It is used to paint wood because of its dark brown color. This mineral can produce higher resolution colors that do not fade over time, which cannot be achieved with other natural and synthetic materials. In addition, it is used as a dark brown color in wood paintings. Due to the unique chemical and physical properties of Gilsonite, it can provide useful properties for wood paintings.

Gilsonite Paint and Coat Grade to use in Pipe Coat:

 

Maximum water and weather resistance is obtained by using a paint containing Gilsonite coat and the gasproofed Tung oil or Oiticica oil (or mixtures of the two) without the addition of any other drying oil, but it is found that while this combination is commercially usable, it is difficult to brush, and it is preferred to add a viscosity reducing drying oil. For this purpose it is found that Perilla oil is particularly satisfactory. Other drying oils such as Linseed, Soybean, Sunflower seed, Hemp seed, Menhaden, or Sardine oil may be used instead of the Perilla oil. The Perilla oil, however, has considerably better drying properties than the other oils mentioned. Gilsonite paint, when fluxed with raw Tung or Oiticica oil, gives an unstable liquid, which will take on excessive body when aging, and one which is not gasproof. On the other hand, when Gilsonite coat is fluxed with Tung or Oiticica oils which have been heattreated with the additions of gums or resins in the ordinary fashion, the resulting paint becomes full of check marks and deteriorates rapidly, particularly upon exposure.

 

The use of the present type of oils, however, results in a paint which does not take on excessive body upon aging and at the same time does not check and deteriorate rapidly upon exposure. Driers, such as Lead (Pb), Cobalt (Co), or Manganese Oxide, or the like, may be incorporated to control the drying time of the finished paint. Thinning oils such as mineral Spirits, solvent Naphtha, or any good solvent for the Gilsonite paint and the oils may be incorporated to bring the paint to the desired consistency. This normally requires about 50% to 65% by weight of thinning oils.

How to use Gilsonite in coating:

 

While the lower limit of 10% for the Gilsonite coat pigment is lower than will ordinarily be used, a satisfactory and durable paint may be made with as small a proportion of Gilsonite pigment as this by incorporating a small amount of carbon black, say 3% to 5% by weight. The percentage of Tung or Oiticica oil may likewise vary, but the higher the percentage thereof, the more durable will be the film produced. The preferred range is between 25% and 50% of either Tung oil or Oiticica oil, or a mixture thereof. However, the beneficial results of the combination of these gasproofed oils with Gilsonite coating pigment are obtained over the entire range of Gilsonite concentration given.

 

In the above percentages any difference is normally made up by a viscosity reducing oil such as Perilla. In the absence of such oil, however, the Tung or Oiticica oil may be used to complete the paint base. Pigments such as iron oxide, or chrome green may be incorporated to produce paints of attractive colors and great durability. A paint prepared in accordance with this combination not only has greater water and Weather resisting properties, but is more resistant to acids and alkalis than a paint comprising Gilsonite and a drying oil other than the gasproofed Tung oil. The term filmforming constituents as used in the claims denote those portions of the film which do not evaporate following application of the paint, but which remain to form the paint film. The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood there from, but the appended claims should be construed as broadly as permissible in view of the prior art.
