Abstract
An adhesive desiccant deposit comprising a hot melt adhesive (110) and a desiccant (130) dispersed within the substrate (100).
Claims (16)
1. An adhesive desiccant deposit comprising:
a hot melt adhesive;
a desiccant dispersed within said hot melt adhesive, said desiccant selected from the group consisting of silica, calcium oxides, activated carbon, molecular sieves, and combinations thereof; and a cellulose additive to increase the porosity of said bolt met adhesive;
said hot melt adhesive having sufficient porosity to allow water molecules to pass into said hot melt adhesive and contact said desiccant.
a hot melt adhesive;
a desiccant dispersed within said hot melt adhesive, said desiccant selected from the group consisting of silica, calcium oxides, activated carbon, molecular sieves, and combinations thereof; and a cellulose additive to increase the porosity of said bolt met adhesive;
said hot melt adhesive having sufficient porosity to allow water molecules to pass into said hot melt adhesive and contact said desiccant.
2. The desiccant deposit of claim 1 wherein said hot melt adhesive is selected from the group consisting of vinyl acetate, ethyl vinyl acetate, polyurethane, and combinations thereof.
3. The desiccant deposit of claim 1 wherein said desiccant is selected from the group consisting of silica gel, calcium oxide, molecular sieves, activated carbon, and combinations thereof.
4. The desiccant deposit of claim 1 wherein said desiccant is an indicating desiccant.
5. The desiccant deposit of claim 1 wherein said desiccant is a non-indicating desiccant.
6. The desiccant deposit of claim 1 wherein said desiccant is a reversible desiccant.
7. The desiccant deposit of claim 1 wherein said desiccant is an irreversible desiccant.
8. The desiccant deposit of claim 1 wherein said desiccant is a silica gel.
9. An adhesive desiccant tape comprising:
a substrate with a top and a bottom;
a first adhesive layer disposed on said bottom of said substrate;
a removable liner disposed on said first adhesive layer on the side of said first adhesive layer away from said substrate; and an adhesive desiccant deposit disposed on said top of said substrate, said adhesive desiccant deposit comprising a hot melt adhesive which has both a desiccant and a cellulose additive to increase porosity of said hot melt adhesive dispersed within said hot melt adhesive, said desiccant selected from the group consisting of silica, calcium oxides, activated carbon, molecular sieves, and combinations thereof; and said hot melt adhesive having sufficient porosity to allow water molecules to pass into said hot melt adhesive and contact said desiccant.
a substrate with a top and a bottom;
a first adhesive layer disposed on said bottom of said substrate;
a removable liner disposed on said first adhesive layer on the side of said first adhesive layer away from said substrate; and an adhesive desiccant deposit disposed on said top of said substrate, said adhesive desiccant deposit comprising a hot melt adhesive which has both a desiccant and a cellulose additive to increase porosity of said hot melt adhesive dispersed within said hot melt adhesive, said desiccant selected from the group consisting of silica, calcium oxides, activated carbon, molecular sieves, and combinations thereof; and said hot melt adhesive having sufficient porosity to allow water molecules to pass into said hot melt adhesive and contact said desiccant.
10. The desiccant tape of claim 9 wherein said hot melt adhesive is selected from the group consisting of vinyl acetate, ethyl vinyl acetate, polyurethane, and combinations thereof.
11. The desiccant tape of claim 9 wherein said desiccant is selected from the group consisting of silica gel, calcium oxide, molecular sieves, activated carbon, and combinations thereof.
12. The desiccant tape of claim 9 wherein said desiccant is an indicating desiccant.
13. The desiccant tape of claim 9 wherein said desiccant is a non-indicating desiccant.
14. The desiccant tape of claim 9 wherein said desiccant is a reversible desiccant.
15. The desiccant tape of claim 9 wherein said desiccant is an irreversible desiccant.
16. The desiccant tape of claim 9 wherein said desiccant is a silica gel.
