Abstract
Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A method for providing a flexible coating on a surface of a component, the method comprising:
- applying a primer composition to a surface of a component configured to be exposed to a flow of fluid, the primer composition comprising epoxy;
- at least partially curing the primer composition to obtain a primer layer having a dry film thickness ranging from about 20 micrometers to about 100 micrometers;
- applying a first coating composition to the primer layer, the first coating composition comprising titanium dioxide and at least one of trifunctional silane, silanol, or filler;
- at least partially curing the first coating composition to obtain a first coating layer having a dry film thickness ranging from about 100 micrometers to about 250 micrometers;
- applying a second coating composition to the first coating layer, the second coating composition comprising at least one of trifunctional silane, silanol, or filler;
- and
- at least partially curing the second coating composition to obtain a second coating layer having a dry film thickness ranging from about 100 micrometers to about 250 micrometers, at least one of the primer layer, the first coating layer, or the second coating layer being configured to reduce damage to the component from the flow of the fluid, such that the component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2.
A method for providing an elastic coating on a surface of an operational component configured to be exposed to a flow of fluid, the method comprising:
- applying a primer composition to an interior surface of an operational component configured to be exposed to a flow of a fluid when in operation, the primer composition comprising epoxy;
- at least partially curing the primer composition to obtain a primer layer having a dry film thickness ranging from about 20 micrometers to about 100 micrometers;
- applying a first coating composition to the primer layer, the first coating composition comprising titanium dioxide and at least one of trifunctional silane, silanol, or filler;
- at least partially curing the first coating composition to obtain a first coating layer having a dry film thickness ranging from about 100 micrometers to about 250 micrometers;
- applying at least one additional coating composition to the first coating layer, the at least one additional coating composition comprising at least one of trifunctional silane, silanol, filler, or titanium dioxide;
- and
- at least partially curing the at least one additional coating composition to obtain at least additional coating layer, the total dry film thickness of the first coating layer and the at least one additional coating layer ranging from about 500 micrometers to about 1000 micrometers, and at least one of the primer layer, the first coating layer, or the at least one additional coating layer being configured to reduce damage to the operational component from the flow of the fluid, such that the operational component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2.
