Abstract:
An optical fiber is permanently routed easily, quickly, and unobtrusively at a customer premises using an inventive hand tool, without staples or other fasteners. The fiber has an adhesive outer coating that is activated as the fiber is applied by the tool on an exposed surface such as a wall, ceiling, molding, groove, or corner at the premises. When the activated coating hardens, the fiber is bonded to the surface on which it was applied, and the hardened coating also provides physical protection for the fiber. In the disclosed embodiment, the coated fiber is supplied on a spool that mounts on the tool, and the coating is activated by guiding the fiber as it unwinds from the spool through a chamber containing an activating substance. The fiber with the activated coating is then guided to an applicator wheel on the tool which applies the fiber to the surface.
Abstract:
Encapsulated cure systems are provided wherein a curative is incorporated into a solid or semi-solid carrier material whereby mere fracturing or failure of the capsule wall encapsulating such cure systems will not provide for or allow sufficient release of the curative. Also provided are adhesive systems incorporating said encapsulated cure systems.
Abstract:
An initiator, particularly useful for anaerobic compositions and replacing the commonly used hydroperoxides, having the formula ##STR1## In a preferred embodiment, R is a lower alkyl group, and R' is hydrogen and Q is a hydroxyl group.
Abstract:
Stock materials for manual and/or high speed industrial automated bonding applications having a curable pre-applied adhesive or sealant compositions on the bonding surfaces wherein the curative for the pre-applied adhesive or sealant composition is contained within a carrier which prevents its premature release.
Abstract:
The present invention provides improved methods for the chemical synthesis of methylene malonates using the Knovenagel synthesis reaction. The method of the invention provides for improved methylene malonates by significantly reducing or eliminating the formation of alternative and/or deleterious side products, significantly reducing or eliminating unwanted consumption of methylene malonates, and significantly reducing or eliminating the degradation of methylene malonates. These advantages result in methylene malonates, which upon recovery, are of higher quality, greater purity, improved yield and possess overall improved performance characteristics (e.g., improved cure speed, retention of cure speed, improved shelf-life and/or stability).

Abstract:
Surface insensitive, storage-stable, single-package liquid anaerobic adhesive and sealant compositions which are substantially free of amines, especially aromatic and tertiary amines, and imides, especially sulfimides such as saccharine and saccharine-type compounds

Abstract:
Stock packaging materials for manual and/or high speed industrial automated package formation and/or filing and closing applications having a curable pre-applied adhesive compositions applied to one or more seams or closure surfaces wherein the curative for the pre-applied adhesive composition is contained within a carrier which prevents its premature release.
