1. Gilsonite in Paint
Maximum water and weather resistance is obtained by using a paint containing gilsonite coat and the gas-proofed tung or oiticica (or mixtures of the two) oil 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.
We use Other drying oils such as linseed, soya bean, sunflower seed, hemp seed, menhaden, or sardine oil 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, that is, one which will take on excessive body when aging, and one which is not gas-proof.
On the other hand, when we fluxe the gilsonite coat with tung or oiticicaoils and heat-treat 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.
A paint consisting essentially of 20 gallons of petroleum solvent and 10 gallons of linseed oil,10 gallons turpentine, pounds of Gilsonite pigment, 4 gallons varnish mixture consisting of 17.8% pentaerythritol rosin ester, 30.8% dehydrated castor oil, 1.4% of a mixture of lead.
2. Gilsonite in Ink
Especially Gilsonite(natural bitumen) is widely used as the primary carbon black wetting agent for black news inks, headset, toner inks. PUB-LTD Gilsonite Resin competes advantageously with hydrocarbon resins, phenolic resins.
3. Gilsonite in Asphalt
We especially discover that a synthetic flux oil can contain and deliver asphaltites such as gilsonite more easily to an asphalt to improve its properties.
The synthetic flux oil includes the asphaltite and a carrier oil.
Depending on the nature of the carrier oil, the synthetic flux oil maybe or not need to be heated during mixing and incorporation into the asphalt.
4. Gilsonite in Construction
We disclose the Gilsonite cement compositions which utilize petroleum asphalt, natural bitumen, a reactive oil and an elastomer.
These compositions produce superior Gilsonite cement that can give low viscosity during application followed by high viscosity, toughness and tenacity after curing on the highway.
Shove resistance is resistance to permanent, longitudinal displacement of a localized area of the pavement surface caused by traffic pushing against the pavement.
Heavy hydrocarbon that can be derived from, without limitation, natural asphalt (Gilsonite), shale asphalt, bottoms from a solvent deasphalting process, hard asphalt or blown asphalt, stiff refined asphalt, a flux. Asphalt is usually the base ingredient for the primer and the binder.
Actully primer can be asphalt, fibers, processing agent, polymeric or elastomeric additive, or asphalt-derived. Actully primer melts to the aggregate. Asphalt binders without polymers are referred to as “neat”.
Fibers including but not limited to, mineral or cellulose.
Actually processing agent including but not limited to, oligiomeric wax, carboxilated, derivative of oligiomeric wax.
Gilsonite is an additive for foundry sand prebends providing reduced smoke and other emissions.
The additive comprising a mixture iron oxide and highly volatile carbonaceous material, metallurgical coke.
The additive is used as one quarter of the foundry sand prebend, the other three quarters consisting essentially of clays.
