摘要:
The present invention relates to cyanoacrylate compositions in non-flowable and gel forms. More particularly, the present invention relates to non-flowable cyanoacrylate compositions which can be packaged in a convenient pocket-sized applicator dispenser for use in spreading the cyanoacrylate compositions onto substrates.
摘要:
This invention relates to a visible light or UV/visible light and anaerobically curable composition for encapsulating the surface of the primer mix disposed in the primer cup, particularly for use in center fire ammunition.
摘要:
A curable composition having enhanced cure speed which includes a curable component, a cure system and an additive for enhancing cure speed. The additive includes an alkali metal halide salt and the reaction product of: (a) a polyfunctional isocyanate and a member selected from the group consisting of an hydroxy and an amine; or (b) a phosgene or phosgene derivative, and a compound having 3 to 7 polyethylene glycol ether units terminated at one end with an ether group and at the other end with a reactive functional group selected from the group consisting of an amine, an amide, a thiol and an alcohol; or (c) a monohydroxy compound, a diisocyanate and a polyamine. Alternatively, in place of or in combination with the cure speed enhancing additive, an aromatic substituted (meth)acryl functionalized component may be incorporated into the curable component to achieve enhanced cure speed.
摘要:
A radiation-curable composition which includes a cyanoacrylate component or a cyanoacrylate-containing formulation; a metallocene component; and a polymerizingly effective amount of a photoinitiator to accelerate the rate of cure is provided.
摘要:
An anaerobic adhesive composition having enhanced toughness and resistance to crack propagation, particularly subsequent to thermal exposure, comprising a combination of three monomers consisting of (a) at least one (meth) acrylate monomer, (b) at least one (meth)acrylate-terminated urethane modified acrylonitrile/butadiene prepolymer, and (c) at least one (meth)acrylate-terminated acrylic/polyisocyanate adduct.
摘要:
The present invention is directed to cyanoacrylate-based compositions, which include in addition to the cyanoacrylate component, a thermal-resistance conferring agent, such as an alkylating agent and/or silylating agent, which provides reaction products of the compositions with improved thermal resistance properties.
摘要:
A cyanoacrylate monomer adhesive formulation which has improved thermal properties resulting from the inclusion in the formulation of an effective amount for enhancing the thermal resistance of the cured polymer of a naphthosultone compound having at least one strong electron withdrawing group thereon, suitably a nitro group.
摘要:
Method of forming highly sensitive, high resolution positive photoresist compositions that are developed from polycarbonates derived from t-diols and various diphenols and homopolycarbonates from t-diols, mixed with 2-10% of onium salts wtih complex metal halide counterions. The high sensitivity of the photoresist compositions is due to the thermodynamic stabilities of the resulting incipient dicarbocations and dienes.
摘要:
Dry-to-the-touch compositions containing a curable polymeric matrix and a curable anaerobic composition present within the polymeric matrix are disclosed. In a particularly desirable form, the compositions are moisture curable. The compositions are non-flowable at high temperatures and have an improved solvent resistance once cured.
摘要:
A high pressure connection and method for making a high pressure connection between an existing filter dryer unit and a refrigeration system using a radically curable composition. The radically curable composition can be an anaerobically curable composition.
