摘要:
A coating including polycarbonate-unit-containing polyurethane resin and 5 mass% or more of nonvolatile matter is applied to a traveling metal strip in a state in which the surface temperature of the metal strip is 60°C or lower. Next, the coating applied to the metal strip is baked at 80-250°C, and a coating film having a film thickness of 0.3 µm or greater is formed on the traveling metal strip. The proportion of polycarbonate units to the total mass of resin in the coating film is 10-80 mass%. The traveling metal strip is then wound after being cooling to a surface temperature of 80°C or lower.

摘要:
An object of the present invention is to provide a urethane composition for a coating film waterproof material which does not contain any of specific chemical substances, has work efficiency that is the same as that of a general-purpose highly extensible urethane coating film waterproof material, an elongation rate of a highly extensible urethane coating film waterproof material, and strength of a high-strength urethane coating film waterproof material, has no decrease in weather resistance of a top coat resulting from a plasticizer, and is suitable for a non-bleeding type of coating by hand that is not affected by migration of a low fraction of asphalt. The present invention provides a urethane composition for a coating film waterproof material containing at least a primary material (A) containing an isophorone diisocyanate prepolymer generated by reacting polypropylene glycol which has two or more hydroxyl groups and whose hydroxyl group equivalent is 1,500 or more and short-chain polyhydric alcohol with isophorone diisocyanate and a curing material (B) containing diethyl toluene diamine, water, polypropylene glycol that has 1,500 or more hydroxyl group equivalents containing two or more hydroxyl groups, and a terminal-esterified polyfunctional polyether-based or polyoxyalkylene monoalkyl ether acetate ester-based plasticizer.
摘要:
The present invention relates to a thermoplastic polyurethane, wherein the thermoplastic polyurethane is obtainable by a method comprising the steps of a) reacting a mixture comprising at least one polyester polyol and at least one polyisocyanate; and b) reacting the reaction product of step a) with at least one substituted or unsubstituted diol which contains at least a primary and a secondary OH group.

Die vorliegende Erfindung betrifft hitzehärtende Dichtstoffzusammensetzungen, welche mindestens Epoxidharz, Dicyandiamid oder ein Aminkomplex einer Lewis-Säure, Isocyanatgruppen aufweisendes Polyurethanpolymer ( PUP ) sowie Polyaldimin umfassen. Diese einkomponentigen Dichtstoffzusammensetzungen zeichnen sich durch eine schnelle Hautbildung und eine hohe Zugfestigkeit aus. Aufgrund der kurzen Hautbildungszeit sind sie bestens für den Einsatz als Dichtstoffe im Automobil-Rohbau geeignet, da sie exzellent mit einem KTL-Lack überschichtet werden können.
