High build coating compositions.
CROSS-REFERENCE TO RELATED APPLICATION
On the other hand, in the polyurethane foams of Examples 1 to 22 and 25 to 32, aliphatic isocyanates Crosslinking Agents 1 to 5, 8 and 9 are used as crosslinking agents, in the polyurethane foams of Examples 23 and 24, a melamine derivative Crosslinking Agent 6 is used as a crosslinking agent.
As a result, polyurethane foam is able to be realized that is resistant to collapse. A urethane emulsion 3 to be subsequently described is an example of such a urethane emulsion having a hydrophilic group. This series can satisfy any fields of customer needs.

Flexible cellular polymeric materials – Polyurethane foam for load-bearing applications excluding carpet underlay – Specification. Extruded polystyrene resin foam.
64001 However, the compressive residual strain of polyurethane foam obtained using an aliphatic isocyanate having a number of monomers of 3 or more and a number of functional groups of 3 or more is slightly lower than the compressive residual strain of polyurethane foam obtained using an aliphatic isocyanate having a number of monomers of 2 or less and a number of functional groups of 2 or less.
Carbonate-based urethane emulsion emulsion of urethane having a carbonate grouppH 8, hydrophilic group: Alert me in case of modifications on this product contact us. Consequently, the use of olefin-based foam and acrylics-based foam as sheet-like packing materials and the like is not preferable.
The stirred and mixed raw materials are then applied to is the surface of a sheet that has low air permeability, and after adjusting to a prescribed thickness with a doctor knife and the like, the coated raw materials are dried by heating with an oven or drying oven and the like. While maintaining the same basic characteristics, we have added a series with new features, like high friction, high slidability and high surface strength, through special surface treatment.
A high-performance shock-absorbent series with cushioning and shape traceability properties making it ideal for applications such as shoe insoles and sports pads. Hydrophobic HDI biuret hydrophobic biuret formed from hexamethylene diisocyanatenumber of functional groups: With variety of density lineup, this series corresponds various application, ijs as seals, vibration insulation and shock absorption.
However, cationic foam stabilizers are not preferable since the urethane emulsion is anionic. As a result, polyurethane foams of Examples 1 to 32 and Comparative Examples 1 to 10 are formed. Carbodiimide Crosslinking Agent 8: The polyurethane foam of the present invention is formed by foaming or expansion-molded from raw materials including either an aliphatic isocyanate or melamine derivative, a urethane emulsion and an anionic foam stabilizer.
Audio and video engineering In the case that the aliphatic isocyanate is used as a crosslinking agent, a hydrophobic group is preferably included therein.
PORON® FootPad Physical Properties/Product Availability
Road vehicles engineering In particular, the aliphatic isocyanate preferably has two functional groups such as isocyanate groups. By using the urethane emulsion and the anionic foam stabilizer as raw materials of the polyurethane foam, the cells are able to be made to be very fine and the density of the polyurethane foam is able to be lowered namely, pliability is able to be increased.
You have no items in your shopping cart. In this manner, the use of an anionic foam stabilizer for the foam stabilizer in the raw materials of polyurethane foam, and particularly the use of only an anionic foam stabilizer, makes it possible to realize polyurethane foam having high recovery properties. Although it is possible to use either the aliphatic isocyanate or melamine derivative as a crosslinking agent, the use of the aliphatic isocyanate as is a crosslinking agent is preferable when considering the use of the polyurethane foam as a cushioning material or packing material of electronic equipment and the like.

Can be used as the optimal secondary water sealant for for sealing water in public construction and civil engineering as well as for waterproofing water supply systems in household equipment. As has been described above, the polyurethane foam of the present invention has low density and low hardness. As depicted in FIG. The polyurethane foam according m claim 1, wherein the anionic foam stabilizer includes both ammonium stearate and sodium alkylsulfosuccinate.
As a result, formed is a polyurethane foam 18 that has high strength high tensile strength and in which compressive residual strain is low. Glass and ceramics industries The following provides explanation of an embodiment of the present invention. Click for automatic bibliography generation.
