The present invention is directed to propellant grains having multiple layers consisting of an outer, slow burning, layer composition and an inner, fast burning, layer with desirable progressivity burn rates. The outer, slow burning, layer comprising a first energetic material, a first plasticizer and a first binder and an inner, fast burning, layer comprising a second energetic material, and the same plasticizer as the outer layer, and a second binder. The compositions in the propellant grain provided herein provides for a burn rate energy differential between the outer, slow burning, layer and inner, fast burning, layer of at least 2.

Multi-layered stable propellant composition

Colorimetric explosive detection kits comprising compact and flexible packaging with an explosive collection assembly and detection reagents disposed thereon in a single-easy-to use system.

Package and kit for explosive detection

Explosive detection package

Explosive reagent detecting compositions are provided for detecting explosives containing chlorate and hydrogen peroxide. Such compositions include Ru-EDTA complexes, binuclear aromatic hydroxyl (BAH) and an optional lanthanide salt. Embodiments of these compositions may be combined with a compact and flexible packaging as an easy-to-use kit for detecting the presence of explosives.

Explosive detection compositions and kit

A composition comprising a condensation resin of the formula:

Formaldehyde free guanamine resin for lithographic energy curable inks

A heat-sealable adhesive for dissimilar substrates is disclosed comprising an organic solvent suspension of a graft copolymer of an A-B-A terblock copolymeric rubber, olefin copolymer and olefin terpolymer. Processing conditions are improved over known adhesive preparation conditions.
