The present disclosure relates to a silicone elastomeric coating composition for synthetic leather, particularly silicone-based synthetic leather, a silicone elastomeric coating (e.g., a topcoat) formed as a reaction product of the cure of the coating composition, methods of making the topcoat and synthetic leather utilizing the same and uses of synthetic leather products. The topcoat is designed to provide synthetic leather with an improved abrasion and scratch resistant topcoat.

Coating composition and its uses

A reaction device of a marine SCR system comprises a conveying unit (), a reaction chamber (), at least one catalyst module (), and an air homogenization chamber (), wherein, the conveying unit () includes an input pipeline () and an output pipeline () sleeved outside the input pipeline (). One end of the reaction chamber () is connected to the conveying unit (). The reaction chamber () comprises an inner cylinder () and an outer cylinder () sleeved outside the inner cylinder (), the inner cylinder () is in communication with the input pipeline (), and the outer cylinder () is in communication with the output pipeline (). The catalyst module () is provided between the inner cylinder () and the outer cylinder (). The air homogenization chamber () is connected to the other end of the reaction chamber () and is in communication with both the inner cylinder () and the outer cylinder (). With the reaction device of the marine SCR system whereby the outer cylinder is sleeved outside the inner cylinder, flue gas from the inner cylinder is turned by the air homogenization chamber and then flows back into the outer cylinder. This can not only substantially reduce the size of the reaction device to improve the integration of the SCR system, but also allow the flue gas to turn in the air homogenization chamber and then flow back, so that the flue gas and a reducing agent can be fully mixed in the air homogenization chamber to improve the catalytic reaction efficiency.
