Abstract

A chemical resistant composite glove that includes a first polymeric layer in the shape of a glove; and a second polymeric layer disposed on the first polymeric layer, and wherein the first polymeric layer is specified for one class of chemical resistance and the second polymeric layer is specified for a second class of chemical resistance, and optionally a third polymeric layer, which may be a thin coating, disposed on at least one of first polymeric layer or the second polymeric layer and is optionally specified for a third class of chemical resistance.

First claim

What is claimed is:

1. A chemical resistant composite glove, comprising:
a first polymeric layer in a shape of a glove comprising a nitrile-butadiene material;
a second polymeric layer in a shape of a glove comprising a polychloroprene layer disposed on the first polymeric layer; and
a third polymeric layer in a shape of a glove that is at least one of a butyl material, a polyacrylic material, a polyurethane material, a nitrile-butadiene material, a natural rubber, or a synthetic polyisoprene disposed on at least one of the first polymeric layer or the second polymeric layer.

2. The chemical resistant composite glove of claim 1 , further comprising a thin coating disposed on the first polymeric layer, wherein the third polymeric layer is disposed upon the second polymeric layer.

3. The chemical resistant composite glove of claim 2 , wherein the thin coating comprises a composition having approximately 18-20% total solids content.

4. The chemical resistant composite glove of claim 2 , wherein the thin coating comprises at least one of a polyacrylic material, a polyurethane material, a nitrile-butadiene material, a natural rubber, or a synthetic polyisoprene.

5. The chemical resistant composite glove of claim 2 , wherein the thin coating is approximately 0.001″ to 0.003″ in thickness.

6. The chemical resistant composite glove of claim 1 , wherein the second polymeric layer comprises a textured surface having multi-faceted cavities.

7. A method for forming a chemical resistant composite glove, comprising:
coating a hand shaped former with a coagulant;
disposing a first layer of a polymeric material on the former, wherein in the first layer comprises a nitrile-butadiene material;
disposing a second layer of a polymeric material onto the first layer, wherein the second polymeric layer comprises a polychloroprene material; and
curing the first layer of a polymeric material and the second layer of a polymeric material.

8. The method of claim 7 , further comprising disposing a third layer of a polymeric material on the second layer of a polymeric material, wherein the third layer of a polymeric material comprises at least one of a polyacrylic material, a polyurethane material, nitrile-butadiene material, a natural rubber or a synthetic polyisoprene material.

9. The method of claim 8 , wherein disposing a third layer of a polymeric material on the second layer of a polymeric material is performed before the curing the first and second layers of polymeric material.

10. The method of claim 8 , wherein the third layer of a polymeric material is disposed as a thin coating of a polyacrylic material, a polyurethane material, a nitrile-butadiene material, a natural rubber or a synthetic polyisoprene material having a total solids content of approximately 18-20%.

11. The method of claim 10 , wherein the third layer of a polymeric material is disposed as a thin coating of a polyacrylic material, a polyurethane material, a nitrile-butadiene material, a natural rubber or a synthetic polyisoprene material having a thickness of approximately 0.001″ to 0.003″ in thickness.

12. A chemical resistant composite glove, comprising:
a first polymeric layer in a shape of a glove comprising a polychloroprene material; and
a second polymeric layer in a shape of a glove comprising a nitrile-butadiene material disposed on the first polymeric layer.

13. The chemical resistant composite glove of claim 12 , comprising a third polymeric layer disposed on at least one of the first polymeric layer or the second polymeric layer.

14. The chemical resistant composite glove of claim 13 , wherein the third polymeric layer comprises at least one of a polyacrylic material, a polyurethane material, a nitrile-butadiene material, a natural rubber material, or a synthetic polyisoprene material.

15. The chemical resistant composite glove of claim 13 , wherein the third polymeric layer is a polymeric composition having a total solids content of approximately 18-20%.

16. The chemical resistant composite glove of claim 1 , wherein the third polymeric layer is a skin-contacting layer.

17. The chemical resistant composite glove of claim 1 , wherein the third polymeric layer is a thin nitrile layer that is a skin-contacting layer.

18. The chemical resistant composite glove of claim 1 , wherein the third polymeric layer is disposed on the first polymeric layer.

19. The chemical resistant composite glove of claim 1 , wherein the first polymeric layer is chemically resistant to a chemical selected from the group consisting of weak acid, acetic acid, hydrocarbon, acetonitrile, acrylamide, carbon tetrachloride, chloroform, and salt solution.

20. The chemical resistant composite glove of claim 1 , wherein the second polymeric layer is chemically resistant to a chemical selected from the group consisting of organic acid, inorganic acid, alcohol, alkaline solution, and oil.

21. The chemical resistant composite glove of claim 1 , wherein the third polymeric layer is chemically resistant to a chemical selected from the group consisting of acetone, aldehyde, and ketone.
