Compositions and processes for assembling appliances
View Patent ↗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.
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.
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.
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.
14. The method of claim l, wherein the first substrate comprises a metal range frame and the second substrate comprises a glass cooktop.
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.
