Abstract

A method of assembling an appliance using a curable silicone composition optionally containing spacer beads of an appropriate size to permit adhesively joining the appliance parts in a desirably spaced-apart arrangement.

Claims

1. A method of assembling an appliance comprising the steps of:

providing a first substrate and a second substrate, each substrate having interior surfaces for bonding together;

depositing a curable silicone composition comprising silicone resin and spacer beads on at least one of the interior surfaces of the substrates;

positioning the interior surfaces in mating arrangement;

permitting the weight of one of the first or second substrates to compress the curable silicone composition to a desired spacing between the substrates; and

permitting the curable silicone composition to cure, wherein the spacer beads have an average diameter of between about 0.005″

to about 0.05″

.

2. The method of claim 1 wherein the spacer beads are selected from the group consisting of glass beads, plastic beads, elastomeric beads, hollow beads, solid beads and combinations thereof.

4. The method of claim 1, wherein the depositing step comprises applying a continuous line of silicone composition perimetrically along the interior surface of one or more of the substrates.

5. The method of claim 1, wherein the depositing step comprises applying spots of adhesive discontinuously along the interior surface of one or more of the substrates.

6. The method of claim 1, wherein the silicone composition is a one-part silicone.

7. The method of claim 1, wherein the silicone composition is selected from the group consisting of an oxime-containing silicone resin, alkoxy-containing silicone resins, methacryl-containing silicone resins, vinyl-containing silicone resins and combinations thereof.

8. The method of claim 1, wherein the silicone composition is a room temperature vulcanizing composition.

9. The method of claim 1, wherein the silicone composition is a two-part silicone.

10. The method of claim 1, wherein the silicone composition is a dual cure silicone.

11. The method of claim 1, wherein the silicone composition is a heat cure silicone.

12. The method of claim 1, wherein the first substrate comprises a metal base unit.

13. The method of claim 1, wherein the second substrate comprises a glass substrate.

3. A method of assembling an appliance comprising the steps of:

providing a first substrate and a second substrate, each substrate having interior surfaces for bonding together;

depositing a curable silicone composition comprising silicone resin and spacer beads on at least one of the interior surfaces of the substrates;

positioning the interior surfaces in mating arrangement;

permitting the weight of one of the first or second substrates to compress the curable silicone composition to a desired spacing between the substrates; and

permitting the curable silicone composition to cure, wherein the spacer beads are present in amounts of about 0.5 to about 10.0% by weight of the silicone composition.

15. The method of claim 3 wherein the spacer beads are selected from the group consisting of glass beads, plastic beads, elastomeric beads, hollow beads, solid beads and combinations thereof.

16. The method of claim 3, wherein the depositing step comprises applying a continuous line of silicone composition perimetrically along the interior surface of one or more of the substrates.

17. The method of claim 3, wherein the depositing step comprises applying spots of adhesive discontinuously along the interior surface of one or more of the substrates.

18. The method of claim 3, wherein the silicone composition is a one-part silicone.

19. The method of claim 3, wherein the silicone composition is selected from the group consisting of an oxime-containing silicone resin, alkoxy-containing silicone resins, methacryl-containing silicone resins, vinyl-containing silicone resins and combinations thereof.

20. The method of claim 3, wherein the silicone composition is a room temperature vulcanizing composition.

21. The method of claim 3, wherein the silicone composition is a two-part silicone.

22. The method of claim 3, wherein the silicone composition is a dual cure silicone.

23. The method of claim 3, wherein the silicone composition is a heat cure silicone.

24. The method of claim 3, wherein the first substrate comprises a metal base unit.

25. The method of claim 3, wherein the second substrate comprises a glass substrate.

26. The method of claim 3, wherein the first substrate comprises a metal range frame and the second substrate comprises a glass cooktop.

14. The method of claim l, wherein the first substrate comprises a metal range frame and the second substrate comprises a glass cooktop.
