Abstract
An infiltrant system for rapid prototyping processes. The infiltrant system generally includes a resin component and a hardener component. The resin component typically includes an epoxy resin, and a diluent. The hardener component typically includes an amine, optionally an amide, and optionally a catalyst. High strength infiltrant systems, flexible infiltrant systems, and a method for infiltrating a part are also described.
Claims55
A two component high strength infiltrant system comprising:
- a resin component comprising:
- about 70 to about 90% by weight of resin component of an epoxy resin;
- and
- about 10 to about 30% by weight of resin component of a diluent;
- and
- a hardener component comprising:
- an amine selected from unmodified aliphatic amines, modified aliphatic amines, unmodified cycloaliphatic amines, modified cycloaliphatic amines, or combinations thereof;
- an amide selected from modified amidoamines, unmodified amidoamines, or combinations thereof;
- and
- optionally a catalyst;
- wherein the infiltrant system has a mixed viscosity of less than 150 cps.
A two component high strength infiltrant system comprising:
- a resin component comprising:
- about 70 to about 90% by weight of resin component of an epoxy resin;
- and
- about 10 to about 30% by weight of resin component of a diluent;
- and
- a hardener component comprising:
- about 20 to about 80% by weight of hardener component of an amine selected from unmodified aliphatic amines, modified aliphatic amines, unmodified cycloaliphatic amines, modified cycloaliphatic amines, or combinations thereof;
- about 20 to about 70% by weight of hardener component of an amide selected from unmodified amidoamines, modified amidoamines, or combinations thereof;
- and
- 0 to about 10% by weight of hardener component of a catalyst;
- wherein the infiltrant system has a mixed viscosity of less than about 150 cps.
A two component flexible infiltrant system comprising:
- a resin component comprising:
- about 70 to about 90% by weight of resin component of an epoxy resin;
- and
- about 5 to about 20% by weight of resin component of a difunctional reactive diluent;
- and
- about 5 to about 10% by weight of resin component of a monofunctional reactive diluent;
- and
- a hardener component comprising:
- about 30 to about 90% by weight of hardener component of an amine selected from unmodified aliphatic amines, modified aliphatic amines, unmodified cycloaliphatic amines, modified cycloaliphatic amines, or combinations thereof;
- and
- about 10 to about 40% by weight of hardener component of an amide selected from polyamides and mixtures thereof.
A two component flexible infiltrant system comprising:
- a resin component comprising:
- an epoxy resin;
- and
- about 5 to about 30% by weight of resin component of a difunctional reactive diluent;
- about 5 to about 10% by weight of resin component of a monofunctional reactive diluent;
- and
- a hardener component comprising:
- an amine selected from unmodified aliphatic amines, modified aliphatic amines, unmodified cycloaliphatic amines, modified cycloaliphatic amines, or combinations thereof and
- an amide selected from polyamides and mixtures thereof.
