摘要:
An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.
摘要:
A curable primer composition comprising:(a) a curable component such as methacrylate; (b) a cure initiating component; and (c) a polymer material selected from the group consisting of: (i) block polymers represented by S-A-S where S is polystyrene and A stands for a polymer or copolymer formed from one or more of ethylene, propylene, butylene, and styrene, which are optionally substituted with carboxylic acid or maleic anhydride; provided that when A comprises styrene then A is a copolymer of styrene with at least one of ethylene, propylene and butylene, and is optionally substituted with carboxylic acid or maleic anhydride; and (ii) any combination of said polymer materials. The composition is applied to a part then photocured. It is dry to touch. Thereafter a thermoplastic material such as a polyolefin is overmolded (e.g. injection molded) over the applied composition. It enhances bond strength of the polyolefin to the part.

The disclosed conformable coating provides a highly durable and resilient film useful for protecting and repairing surfaces such as skin and mucous membranes. The coating comprises 0.1% to 65% wt. of a polymerized cyanoacrylate monomer and at least 35% wt. of an elastomer phase. The conformable coating composition comprises a polymerizable cyanoacrylate monomer, an elastomer, and a volatile liquid. The cyanoacrylate monomer is 0.1 to 65% wt. of the nonvolatile portion, the elastomer in an elastomer phase is at least 35% wt. of the nonvolatile portion, and the volatile liquid is at least 40% wt. of the total composition.

A thermally expandable material is provided that, once expanded, has a Young's storage modulus E' between 0.1 MPa and 1000 MPa, a loss factor of at least 0.3 (preferably, at least 1) and a shear storage modulus G' preferably between 0.1 MPa and 500 MPa at a temperature between -10 and +40 degrees C in the frequency range 0 to 500 Hz. Such materials are useful in connection with reducing the transfer of vibrations from a vibration generator, as may be present in a vehicle.
摘要:
The present invention is directed to a primer composition. The primer composition comprises a maleated thermoplastic elastomer, a non-halogenated polyolefin, and a resin. In some embodiments, the primer comprises a crosslinking agent, for example 2,4-bis(trichloromethyl)-6-4'-methoxyphenyl-sym-triazine. In other embodiments, the primer comprises an epoxy. The invention is also directed to a tape comprising a substrate, a primer coated on at least one surface of the substrate, the primer comprising a maleated rubber, a non-halogenated polyolefin and a resin, and a pressure sensitive adhesive coated on the primer.
摘要:
The present invention concerns a bituminous composition which comprises a bituminous component (A), an elastomer component (B), preferably a block copolymer of a conjugated diene and a monovinylaromatic hydrocarbon, and an additive (C), wherein the additive is a compound of the general formula Ar---R---Ar (I) wherein each "A" independently is a benzene ring or fused aromatic ring system of 6 to 20 carbon atoms, substituted by at least one hydroxyl group, and "R" is an optionally substituted divalent radical comprising 6 to 20 atoms in the backbone and at least one amide and/or ester group in the backbone, and its use in roofing applications.
