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.

Claims (29)

1 . A chemical resistant composite glove, comprising:

a first polymeric layer in a shape of a glove comprising a nitrile-butadiene material; and

a second polymeric layer comprising a polychloroprene layer disposed on the first polymeric layer, wherein the second polymeric layer is specified for a second classification of chemical resistance and the first polymeric layer is specified for a first classification of chemical resistance.

2 . The chemical resistant composite glove of claim 1 , comprising a third polymeric layer disposed on at least one of the first polymeric layer or the second polymeric layer and is specified for a third classification of chemical resistance.

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

4 . The chemical resistant composite glove of claim 1 , comprising a thin coating having a thickness from about 0.001 inches to 0.003 inches disposed on an interior surface of the first polymeric layer.

5 . The chemical resistant composite glove of claim 4 , wherein the thin coating comprises a composition having approximately 18-20% total solids content.

6 . The chemical resistant composite glove of claim 4 , 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.

7 . The chemical resistant composite glove of claim 4 , wherein the thin coating is approximately 0.001″ to 0.00225″ in thickness.

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

9 . 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 first polymeric layer is specified for one classification of chemical resistance and the second polymeric layer is specified for a second class classification of chemical resistance; and

curing the first layer of a polymeric material and the second layer of a polymeric material.

10 . The method of claim 9 , wherein the second polymeric layer comprises a polychloroprene material.

11 . The method of claim 9 , further comprising disposing a third layer of a polymeric material on the second layer of a polymeric material.

12 . The method of claim 11 , 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.

13 . The method of claim 11 , wherein the third layer of a polymeric material is disposed before the curing the first and second layers of polymeric material.

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

15 . The method of claim 14 , 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 0.00225″ in thickness.

16 . The method of claim 14 , wherein the low total solids content is 18-20%.

17 . 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 comprising a nitrile-butadiene material disposed on the first polymeric layer, wherein the second polymeric layer is specified for a second classification of chemical resistance and the first polymeric layer is specified for a first classification of chemical resistance.

18 . The chemical resistant composite glove of claim 17 , comprising a third polymeric layer disposed on at least one of the first polymeric layer or the second polymeric layer and is specified for a third classification of chemical resistance.

19 . The chemical resistant composite glove of claim 18 , 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.

20 . The chemical resistant composite glove of claim 18 , wherein the third polymeric layer is disposed as a thin coating having a thickness of approximately 0.001″ to 0.003″, comprised of a polymeric composition having a total solids content of approximately 18-20%.
