摘要:
Hardenable molding masses are disclosed containing an organic binder material, fillers and additives wherein the binder material after the shaping and hardening is pyrolytically decomposed. The development of harmful substances such as aromatic hydrocarbons is considerably reduced through the addition of a boron containing compound.
摘要:
A transparent moisture-resistant mercaptan composition is made utilizing an amino-titanate catalyst. The composition can be utilized in association with high heat-resistant transparent compositions containing a boroxine compound.
摘要:
Polymerizable adhesives mixtures containing ethylenic double bonds capable of polymerizing and boron compounds as polymerization initiators, wherein the boron compounds are organoboron compounds and contain at least one boron-carbon bond or one boron-hydrogen bond and have practically no spontaneous combustibility in air. The adhesives harden after a short time to give stable adhesive bonds, even in the presence of moisture.
摘要:
Synergistic fire retardants for wood and other cellulosic materials which are substantially non-hygroscopic and which do not require high curing temperatures in the material treated are formed of the partial reaction product of dicyandiamide, phosphoric acid, boric acid and water wherein the combined weight ratio of dicyandiamide and phosphoric acid to boric acid is from about 60 to about 40 to from about 90 to about 10.
摘要:
A high heat resistant transparency of epoxy resins cured with adducts of trimethoxyboroxine and benzyl alcohol is disclosed to resist intense heat for these transparencies in their use on military and industrial hardware. Additionally, the transparency may include phosphite or phosphate compounds to improve heat resistance, with the phosphate compound in sufficient concentrations to delay gel times such that the phenyl substituted alkyl alcohol may be eliminated from the composition. This transparency may exist in a composite with other layers of transparent material known to those skilled in the art. The epoxy transparency layer is bound to the other transparent layers, in a variety of configurations, using an interlayer of mercaptan terminated resins. These resins greatly improve resistance to moisture permeability in and about the edges of the entire transparency.
摘要:
Concentrated boric anhydride solutions containing more than 5% of boric anhydride in an organic solvent selected from mono or polyalcohols, trialkylborate and/or dialkylacetal when the solvent also contains an acid selected from sulfuric acid and/or aromatic acids. These solutions are used as hardeners of formo-phenolic resols, more particularly for the manufacture of laminates comprising glass fibers and formo-phenolic resols.
摘要:
The viscosity stability of hot melt adhesives containing an elastomeric linear EPDM, branched ethylene/propylene copolymer, or propylene/hexene-1 dipolymer is markedly improved by inclusion in the adhesive composition of boric acid, boric anhydride, or a boric acid ester, in combination with a phenolic antioxidant.

摘要:
THE PRESENT INVENTION RELATES TO AN ORGANOBORON COMPOUND HAVING A NEW STRUCTURE, MORE SPECIFICALLY TO AN ORGANOBORON COMPOUND CHARACTERIZED BY A DISLOCATION OF ITS STRUCTURE WHICH IS NORMALLY IN NON-IONIC CONDITION BUT MAY ASSUME AN ANIONIC CONDITION CHRACTERIZED BY SURFACE ACTIVITY; TO A PROCESS FOR PRODUCING THIS ORGANOBORON COMPOUND, AND TO ITS APPLICATION AS AN ANTISTATIC AGENT, EMULSIFIER AND HEAT-RESISTANCE IMPROVING AGENT FOR SYNTHETIC RESINS.
