Abstract
A siloxane compound is useful as a bonding agent in an adhesive formulation or sealant formation. A kit-of-parts can contain the siloxane compound. A corresponding method can be used to synthesize the siloxane agent.
Claims11
A kit-of-parts for providing an adhesive formulation or a sealant formulation, comprising at least one siloxane compound comprising:
- at least one building block according to formula (A)
- wherein
- Ra is selected from the group consisting of
- in which
- Ra1, Ra4, Ra5, Ra6, and Ra7 are independently selected from the group consisting of alkyl group and aryl group,
- Ra2 is selected from the group consisting of hydrogen and methyl group,
- each Ra3 is independently selected from the group consisting of hydrogen and methyl group,
- c is an integer ranging from 1 to 40,
- d, e, f, and g are integers independently ranging from 2 to 6,
- Rw is an alkyl group,
- each Rx is independently selected from the group consisting of hydroxy group, oxyalkyl group, oxyalkanediyloxyalkyl group, oxyaryl group, and oxyacyl group,
- w is selected from 0 and 1, and
- x is selected from 0, 1, and 2,
- with the proviso that a sum of w and x ranges from 0 to 2,
- and
- at least one building block according to formula (B)
- wherein
- Rb is selected from the group consisting of
- in which
- L is a C3-C8-alkanediyl group,
- Rb1, Rb2, and Rb3 are selected from the group consisting of alkyl group and aryl group, h, i, and j are integers independently ranging from 2 to 6,
- each Ry is independently selected from the group consisting of hydroxy group, oxyalkyl group, oxyalkanediyloxyalkyl group, oxyaryl group, and oxyacyl group,
- Rz is an alkyl group,
- y is selected from 0, 1, and 2,
- z is selected from 0 and 1,
- with the proviso that a sum of y and z ranges from 0 to 2,
- or a salt of the siloxane compound,
- the kit-of-parts comprising:
- at least a component C1, and
- a component C2,
- wherein the component C1 comprises the at least one siloxane compound, and optionally, at least one additive selected from the group consisting of a filler, a pigment, a dye, a plasticizer, a rheology aid, a bonding agent, a tackifier resin, a desiccant, a solvent, a defoamer, a UV stabilizer, an antioxidant, a catalyst for a crosslinking reaction of the siloxane compound, a hydrolysis stabilizer, a reactive diluent, an adhesive resin, a flame retardant, an adhesion promoter, a further additive which imparts a property to the adhesive formulation or the sealant formulation, and a mixture of two or more of aforementioned additives;
- and
- wherein the component C2 comprises water.
30 more elements
A method for applying an adhesive- or sealant formulation onto a least a portion of at least one surface, the method comprising:
- a) providing the at least one surface, and
- b) treating said at least one surface with a mixture of an adhesive or sealant formulation from the kit of parts.
