Abstract
An adhesive formulation including an acrylate monomer and/or a methacrylate monomer, a chlorosulfonated polymer resin, and a reducing agent. The adhesive also includes a cycloheteroatom zirconate or a cycloheteroatom titannate, which is utilized as a cure profile regulator. Further, the adhesive includes toughening-agent copolymers having a very low Tg to increase impact strength of the cured adhesives at low temperatures.
Claims9
A method of manufacturing an adhesive, comprising:
- preparing a first part comprising an acrylate monomer or a methacrylate monomer, or a combination thereof, and a chlorosulfonated polymer;
- and
- preparing a second part separate from the first part, the second part comprising a reducing agent and a cure profile regulator, wherein the cure profile regulator comprises a cycloheteroatom zirconate or a cycloheteroatom titannate, or a combination thereof.
A method of using an adhesive, comprising:
- mixing a first part of the adhesive with a second part of the adhesive, wherein:
- the first part comprises an acrylate monomer or a methacrylate monomer, or a combination thereof, and a chlorosulfonated polymer resin;
- and
- the second part comprises a reducing agent and a cure profile regulator, the cure profile regulator comprising a cycloheteroatom zirconate or a cycloheteroatom titannate, or a combination thereof;
- applying a mixture of the first part and second part to a first substrate;
- and
- bonding a second substrate to the first substrate.
A method of bonding two objects, comprising:
- providing a first object and a second object;
- applying an adhesive to the first object, wherein the adhesive is formed by combining a first part of the adhesive and a second part of the adhesive, wherein:
- the first part comprises an acrylate monomer or a methacrylate monomer, or a combination thereof, and a chlorosulfonated polymer resin;
- and
- the second part comprises a reducing agent and a cure profile regulator, wherein the cure profile regulator comprises a cycloheteroatom zirconate or a cycloheteroatom titannate, or a combination thereof;
- and
- adhering the first object and the second object via the adhesive.
A product, comprising:
- components bonded with an adhesive comprising the following formulation:
- an acrylate monomer or a methacrylate monomer, or a combination thereof;
- a chlorosulfonated polymer resin;
- and
- a cure profile regulator comprising a cycloheteroatom zirconate or a cycloheteroatom titannate, or a combination thereof.
A product, comprising:
- components bonded with an adhesive comprising the following constituents:
- an acrylate monomer or a methacrylate monomer, or a combination thereof;
- a chlorosulfonated polymer resin;
- and
- a copolymer having a glass transition temperature less than −50° C. of at least one domain of the copolymer.
