PURPOSE: To efficiently obtain a polyurethane-based resin for lens, low in specific gravity, high in refractive index, excellent in low dispersibility, and weatherability, thus useful for optical elements, etc., by reacting a sulfur atom- containing polyisocyanate compound with a specific polyol com...
Wall or floor coating comprising a number of layers (2, 3, 4). One or more of the layers (2) is made of compact disks placed adjacent to each other. The spaces between the disks are filled with plastic, resin or lacquer. An Independent claim is made for a method for producing a wa...
Plastic lenses are also known as CR-39 ("Columbia resin 39”). This material has been widely used in eyewear since the 1970s and is still a popular choice among people who wearprescription glasses. Previously, lenses were made of crown glass and were heavy and more likely to shatter. The...
Let’s start with plastic. The typical thin and flimsy plastic bag is made of high-densitypolyethylene, commonly known as HDPE. Producing this material requires extractingpetroleumfrom the ground and applying extreme heat. The resulting polymer resin is then transported alongside additional ingredients ...
From the pictures, I expected them to be larger, and plastic. All good, though, these tiny wood ones worked fine. It’s pretty sturdy on the programming headers. Clips on quickly, and doesn’t need soldering! Success! To make this more repeatable and less like an epoxy-globbed-on mess...
plastic secured thereto for inflation. Following inflation of the voids within the assembly, the uncured resin is responsive to the introduction of a curing agent to all inner surfaces for curing the resin into a solid, resulting in a rigid high-strength self-supporting building or housing ...
The road- and escape path marking (1) consist of multicomponent plastic or epoxy resin, which is applied in fluid or viscous condition for identifying asphalt, concrete or other floor covering to bond with building material of a durable connection. The marking is glowable and/or daily luminous...
The present invention relates to a process for producing a resin useful in plastic lenses, to plastic lenses containing the resin and to a process for producing the lenses. The resin is produced from reaction of one or more isothiocyanate compounds with one or more active hydrogen containing comp...
As little as 5% of resin added to a phenol-oil complex gives when baked a solid but flexible, tough product that is useful as a binder in floor coverings, cements, filling and caulking materials or as a flexible durable water-resistant coating for paper, fabric, metal and the like; the ...
