The present disclosures are directed to a silane coupling agent, two silane functional polymers, a method of making a silane coupling agent, the use of a silane coupling agent for making a silane functional polymer, a method of making a silane functional polymer by removing a protecting group, and a composition comprising one or more silane functional polymers.

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.

The present invention relates to moisture curable compositions based on silane-terminated polymers in paste form that can be used as 3D printing materials and provide isotropic and elastomeric properties. The invention further relates to the use thereof as 3D printing materials and printing methods using said compositions.

Disclosed are polyurethane-based foams. The foams may have one or more vicrucidal/bactericidal agents. The foams may be used as filters that capture and/or inactivate viral particles, such as, virions associated with COVID-19. Also described are methods of making the foams and methods of using the foams.
