Abstract:
The present invention relates to a multilayer polyurethane roofing system. An important aspect of the invention is the use of multilayers of polyurea with the base layer having minimum thickness of 40 mils, thus forming a waterproofing membrane. The multiple layers of polyurea provide increased structural strength, as well as reduce failures caused by applicator error. Moreover, in applications where the polyurethane is applied to insulation board stock, the polyurea membrane is isolated from movements between the base insulation and the roof deck (i.e., wood, metal, concrete decking). Figure 1 shows a multilayer polyurea roofing system in accordance with one embodiment of the present invention.
Abstract:
This invention is to provide a method for surface-treatment of a water absorbent resin excelling in water absorption properties. This invention relates to a method for the surface-treatment of a water absorbent resin, which comprises: a) mixing 100 parts by weight of a water absorbent resin, 0.01 - 20 parts by weight of at least one radical polymerization initiator selected from the group consisting of persulfates, hydrogen peroxide, and azo compounds, and a radically polymerizing compound and b) irradiating the resultant mixture with active energy rays. The treatment particularly exalts the absorption ratio against pressure and the saline flow conductivity.
Abstract:
This invention provides novel methods for creation of patterned lipid bilayer membranes as well as methods for refunctionalization of such patterned membranes with selected components. Such components optionally comprise, e.g., lipid bilayer membranes (140), such as PBS, which optionally comprise specific proteins, non-biologic moieties, etc. The lipid bilayer may be in an acqueous phase (136), and support supported on a substrate (160), resting on a hydration layer (150). The patterning technique may employ a mask with UV transparent areas (120) and UV opaque areas (110). The patterned irradiation results in a hole/emptied areas (170) in the exposed areas.
Abstract:
Protective coatings are disclosed. Methods of applying the protective coatings are also disclosed, where a transfer pad (10), comprising a deformable body (14) and having a layer of protective coating solution (7), is transferred on to the surface (92) of a device (90) to be coated on a support/indexing plate (94), then moved under radiation source (99) to cure layer (19) applied to the device.
Abstract:
The present invention describes a method and an apparatus for plasma coating the inside surface of a container to provide an effective barrier against gas transmission. The method provides a way to deposit rapidly and uniformly very thin and nearly defect-free layers of polyorganosiloxane and silicon oxide on the inner surface of a container to achieve more than an order of magnitude increase in barrier properties.
Abstract:
The invention relates to a method for producing UV absorption layers on organic or inorganic substrates. The inventive method consists in a) acting by a low-temperature plasma, or a corona discharge, or energy-rich radiation on an organic or inorganic substrate, b) in applying at least one radical forming initiator and at least one UV absorber containing at least one unsaturated ethylene group, and a synergist agent and/or an unsaturated ethylene compound eventually in the form of a molten material, solutions, suspensions or emulsions to said organic or inorganic substrates; and c) heating the coated substrate and/or irradiating it with electromagnetic waves. The inventive substrate provided with an UV absorption layer is also disclosed. Said method generally excludes vacuum conditions, a high energetic or thermal load, and the fracture of the UV absorber. Said invention makes it possible to produce transparent UV absorption layers which exhibit high adherence ability and whose properties are usefully modulated, for example like optical density.
Abstract:
The present invention provides radiation-curable compositions for coating plastic substrates, wherein the compositions, after cure, have a combination of sufficient adhesion, flexibility, and hardness. The compositions include: (a) at least one component comprised of a metal oxide bonded to an organic compound, said organic compound having (i) a radiation curable group; and (ii) a group represented by the following formula (1) wherein X represents an amine (NH), oxygen (O), or sulfur (S) radical; and Y represents an oxygen (O), or sulfur (S) radical; (b) a poly(methacrylate) compound; and (c) an adhesion promoter.
