A method for producing molding sand includes mixing an artificial sand with a furan resin composition including a furan resin precursor, and mixing a curing agent with the artificial sand with which the furan resin composition is mixed, wherein the curing agent includes xylene sulfonic acid.

The present invention is a granular material that can be well recoated regardless of the type of the granular material, and enables a refractory aggregate in an unprinted portion to be used without any regeneration process, in the manufacture of a three-dimensional laminated and shaped mold. This granular material is a granular material for use in three-dimensional laminated mold shaping, and obtained by adding a material that causes a hydration reaction having a moisture absorbing function and generates a catalytic effect to a coating material mixed with or coated with an acid as a catalyst which activates and hardens an organic binder for binding the granular material.

Compositions of matter for use as a roof coating are provided. The roof coating can be applied to any suitable roof of any building. When applied to a roof, the roof coating insulates the building's interior from some of the sun's thermal energy, which would otherwise radiate into the building and raise the interior temperature. The roof coating can therefore reduce energy consumption involved in cooling the building's interior. The roof coating demonstrates advantageous thermal insulation properties (e.g., low thermal conductivity) over a wide range of temperatures and when applied with minimal thickness. The provided roof coating demonstrates high reflectance, high emissivity, low thermal conductivity, low flame spread, high solar reflectance index (SRI) in the range of 100 to 120, and acts as a sealer and waterproofer, which all contribute to its desirable properties for use as a thermally insulating roof coating.

A vehicle coating to thermally insulate the vehicle's interior is provided. The vehicle coating may be applied to the exterior (e.g., roof) of any suitable moving vehicle, such as a bus, RV, delivery truck, construction vehicle (e.g., cement mixer), train car. When applied to a vehicle's exterior, the vehicle coating provides the benefit of insulating the vehicle's interior from some of the sun's thermal energy, which would otherwise radiate into the vehicle and increase the interior temperature. The vehicle coating demonstrates advantageous thermal insulation properties (e.g., low thermal conductivity) over a wide range of temperatures and when applied with minimal thickness. The provided vehicle coating demonstrates high reflectance, high emissivity, low thermal conductivity, and high solar reflectance index (SRI), and is suitable for high vibration high uplift winds, which all contribute to its desirable properties for use as a thermally insulating vehicle coating.

A new and innovative fireproof coating is provided. The fireproof coating exhibits high heat insulation combined with a low flame spread and low smoke density. The fireproof coating can be applied to any suitable structure for which fireproofing is beneficial. An advantage of the fireproof coating is low weight and high flexibility compared to conventional fireproofing technologies while still providing equivalent or better fireproofing properties. The provided fireproof coating has a low thermal conductivity and high emissivity, each of which provide the coating with desirable fireproofing properties. The fireproof coating also demonstrates its advantageous fireproofing properties over a wide range of temperatures and adds minimal thickness to the structures on which it is applied while still providing equivalent or better fireproofing properties as other, thicker fireproof materials.
