摘要:
A feeder for supplying molten streams of glass to be attenuated into fibers is provided comprising a refractory metal core; an oxygen impervious, precious metal sheath and an intermediate diffusion barrier layer intimately bonded together by hot isostatic pressing to form a unitary laminate, said laminate having inserts having orifices extending therethrough adapted to establish streams of molten material for attenuation into filaments.

摘要:
Protective coating solutions for cementitious substrates are disclosed which comprise a minor amount of a cyclohexane based organic solvent on a major amount of an asphaltic material. The asphaltic material is a blend of asphalt with the reaction product of asphalt, a vinyl aromatic monomer, a rubber and an unpolymerized acrylamide.
摘要:
An improved chip seal method for treating pavement with aqueous asphaltic emulsions is provided wherein the emulsion is a blend of a conventional emulsion adapted for an aqueous asphaltic emulsion is provided in which the dispersed asphaltic material is the prereacted reaction product of asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), an acrylamide, a vinyl aromatic monomer and an elastomer.

摘要:
Cationic chemically modified asphalts are prepared by reacting asphalt, a vinyl aromatic monomer and an amine derivative of a fatty acid. These asphalts are useful for road construction, repair and maintenance as well as a coating for various substrates including cementitious substrates, glass and metal.
摘要:
A reinforced composite formed of a bitumen, an elastomer or a plastic reinforced with a filler containing a coating thereon in the form of a chemically modified bitumen. The chemically modified bitumen employed is one formed by reaction of a linking agent reactive with the bitumen and containing groups reactive with the filler so that the chemically modified bitumen undergoes a chemical reaction with the filler to thereby intertie the coated filler with the continuous phase.
