A release film comprising a plastic film substrate 3, a first layer 1 provided on at least one side of the substrate, and a second layer 2 provided on the first layer 1. The second layer 2 functions as a release layer and the first layer 1 as an adhesive layer to fix the second layer 2 on the substrate 3. The release film has a small peel force and can be prepared from solvent-free compositions.

It is an object of the present invention to provide a release film which is superior in the flexibility at high temperature, the conformability to circuit patterns, the heat resistance, the releasing property and the non-contaminative property, and easily discarded after use.The present invention relates to a release film, which is used in a manufacturing process of a printed-circuit board, a flexible printed-circuit board or a multilayer printed-circuit board, having a layer comprising a resin ...

The invention provides release agents and methods for preparing textiles and molded articles there from. Lignocellulosic materials, concrete and polyurethane foam can be molded with these release agents. The release agents comprise the salt of tall oil fatty acids, preferably of very high purity. A synthetic wax and/or silicone resin is used with the tall oil fatty acids in preferred embodiments. The tall oil fatty acids contain less than 10 wt % , based on the total weight of the tall oil fatty...

An acrylic resin type release agent composition comprising (A) a polymer which comprises a (meth)acrylate containing a constituent unit represented by the following formula (1) and (B) a crosslinking agent which comprises an amino resin, wherein a weight ratio (A)/(B) is in the range of 99.99/0.1 to 30/70: ##STR00001## wherein R.sup.1 is a hydrogen atom or a methyl group, and R.sup.2 is a long-chain alkyl group of 12 to 28 carbon atoms. Also described herein is a release liner having a release l...

Compositions and personal care articles are described comprising a complexed perfume and a coating material which acts to retain the perfume in the complexed state and to keep out other competing materials.

A pull-cable-type of release mechanism incorporating a latch and a spring release, whereby the actuating pressure applied to the mechanism can be multiplied many times in terms of thrust or pull directed to a release cable. The release mechanism includes many safety features including a cocking member lock, safety pin incorporation, and other structural advantages inducing an operator to follow a given procedure to insure that load release will occur when desired.

A release mechanism for stabilizing rollerons of a missile. The device coises a cager of a bar magnet fixed in a slot in the wing of a missile adjacent the rollerons. The cager is shaped and secured so that its inertia causes it to rotate toward the rear when the missile is accelerated forward. In the caged position one end of the cager fits in a recess provided in a nonmagnetic rolleron housing thereby preventing movement of the rolleron relative to the wing. Magnetic attraction between the cag...

Separation of a fastening band is accomplished by firing a small shaped cge device in such a way as to cut a link in the band. The shaped charge device is contained in an adapter which positions the charge over the link and confines the force of the charge to the desired area. The adapter holds the shaped charge device to a timer mechanism in position to be detonated by a stab primer or the like.

An aqueous aerosol composition is composed of a homogenized dispersion of lecithin in water and contains a propellant, e.g., carbon dioxide or nitrous oxide, for pressurizing the composition in an amount sufficient to produce a release coating of lecithin on a surface when the composition is sprayed. Other ingredients such as preservatives, i.e., bacteriostats and/or fungistats, and supplemental emulsifiers can be included where desired or needed.

Disclosed herein is a release paper comprising: a paper base laminated with a release layer, this release layer comprising a 4-methyl-1-pentene resin being a copolymer of 4-methyl-1-pentene and an .alpha.-olefin other than 4-methyl-1-pentene wherein the .alpha.-olefin is contained in a proportion of 6 to 8% by weight. This release paper is excellent in heat resistance and exhibits less curling tendency in repeated use. Further, the release paper exhibits a high bonding strength between resin and...
