Binder coated refractories, casting mold using the same, and method of manufacturing casting mold using the same
The binder coated refractories comprises the refractory aggregates and the solid-form coating layer which comprises the sugar group as the binder and which is provided to the surface of the refractory aggregates. According to this, the sugar group is used as the binder for bonding the refractory aggregates. Further, even if the sugar group is thermally decomposed, the sugar group emits the carbon dioxide and the water. Therefore, there is little likelihood of emitting the harmful gas. Therefore, it is possible to reduce the environmental pollution. Further, the sugar group is thermally decomposed easily. Therefore, it is possible to manufacture the casting mold having the good breaking property.
Formed three-dimensional matrix and associated coating providing modulated release of volatile compositions
Described are bonding modulating coatings configured to provide an improved release profile of a volatile composition from a scent reservoir, wherein the modulating coating includes a barrier substance configured to hinder the release of the volatile composition through the modulating coating. The modulating coating also includes a hygroscopic substance that facilitates the release of the volatile composition through the modulating coating. The barrier substance and hygroscopic substance are mixed in a proportion such that the modulating coating provides a bonding action between adjacent scent reservoirs and may be formulated to maintain bonding even under the application of heat. The bonding modulating coating may then be used to bond a number of scent reservoirs together into a larger, three-dimensional matrix to provide improved scent retention and longevity.

Formaldehyde free binder and multi-component nanoparticle
This patent describes formaldehyde free or formaldehyde reduced binders useful, for example, in a fiber based composite material such as glass or other mineral fiber insulation, non-woven fabric or wood-based board. In one example, melamine is used as an acidic solution or a salt. The salt or solution is used to create an aqueous binder with other components such as a polyol and a crosslinker. A preferred polyol is a nanoparticle comprising high molecular weight starch. In other examples, binders include mixtures of a polyol with urea and a crosslinker. In other examples, a multi-component nanoparticle is made by reacting a polyol such as starch in an extruder with an insolubilizer such as melamine or urea. The resulting particles are mixed with water, optionally with other components such as an additional crosslinker, to create an aqueous binder.

Reduced salt precipitation in carbohydrate containing binder compositions
Methods of reducing salt precipitation from a binder composition are described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition. The binder composition may include a polymerization catalyst. Exemplary sequestrants may include polycarboxylic acids or anhydrides. Exemplary sequestrant concentrations may range from about 2 wt. % or less of the aqueous binder solution.
