| Biological monitoring of isocyanate is possible using albumin adducts and their corresponding diamines in plasma and urine. |
|
| The researchers included an appended isocyanate group so that the precipiton would react with amines. |
|
| Example 1: A linear polyurethane polymer contains aliphatic isocyanate groups only at the chain ends. |
|
| Furthermore, the product offers excellent resistance to salt water, weathering and UV light and is free of solvents and isocyanate. |
|
| A few plants use isocyanate adhesives, primarily for the core layer, where their fast reaction time is most useful. |
|
| Reacts vigorously with phosphorous isocyanate, dimethylformamide solution, hydrochloric acid and dinitroaniline mixtures, and iodine. |
|
| All 2K Hardeners have the following chemical base: Non-yellowing, highly durable isocyanate resin. |
|
| A major breakthrough in the commercial application of polyurethane did not occur until 1941, when a trace of moisture reacted with isocyanate to produce carbon dioxide. |
|
| Foam is manufactured by adding water, which reacts with the terminal isocyanate groups to increase the molecular weight through urea linkages while simultaneously releasing carbon dioxide. |
|
| The selection of the appropriate protective clothing will depend on a number of factors such as the type of paint, isocyanate exposure, how concentrated they are and environmental conditions such as ventilation. |
|
| Suitable cross-linking agents are isocyanate, melamines or silanes. |
|
| One scientific study of workers reported that exposure to isocyanate type chemicals resulted in larger declines in lung function compared to other workers. |
|
| Air Products functionalized the catalysts to react with isocyanate and attach covalently to the polymer network. |
|
| The concentration of isocyanate stated is the percentage by weight of the free monomer calculated with reference to the total weight of the preparation. |
|
| They soon discovered, however, that the foam by itself did the job just as well. Arsenal Medical's technology uses two types of liquid, called polyol and isocyanate. |
|
| Studies have indicated that exposure to substances containing free isocyanate monomers present some health hazards when protective clothing is not worn. |
|
| It is apparent that isocyanate functionality is rapidly consumed by PF nucleophiles as found previously. |
|
| Polyurethane foam is formed by mixing an organic polyol and an isocyanate along with amine or organometal catalysts and a fluorocarbon blowing agent. |
|
| The single worst industrial accident in history occurred on December 3, 1984 when some 45 tons of the dangerous gas methyl isocyanate escaped from the Union Carbide plant in, India. |
|
| The two liquid precursors of a polyurethane are a multifunctional isocyanate and a prepolymer, a low-molecular-weight polyether or polyester bearing a multiplicity of reactive end-groups such as hydroxyl, amine, or amide. |
|
|
|
| The functionality of the polymeric isocyanate is based on how many diisocyanates reacted with the polyol groups. |
|
| The ruptured tank was close to a methyl isocyanate tank which was undamaged by the explosion. |
|
| Vencorex is the owner of key technologies and a major producer of aliphatic isocyanates and aromatic isocyanate used in polyurethane coatings, adhesives, elastomers and inks. |
|
| In the PEPU01 coating system, several factors would be expected to influence the unblocking of the MEKO-blocked isocyanate in solution during heating. |
|
| In the case of PUR foam production, water reacts with isocyanate, forming carbamic acid which decomposes to an amine and carbon dioxide which acts as the foam blowing agent. |
|
| The longer the isocyanate is exposed to moisture prior to use, either in mixed sand of during storage, the greater the chance for the isocyanate to react with water. |
|
| At some point, the tank could no longer withstand the steadily increasing temperature and pressure, and in the end about 50,000 pounds of methyl isocyanate escaped. |
