Problems solved by technology

[0012] Meanwhile, in the case of a compounding method of mixing resin powder and resin pellets to form a blend, and then feeding the blend into an extruder, separation occurs due to the difference in particle size, and thus it is difficult to use an accurate amount of resin. resin component
Therefore, the process is complicated by feeding the resin components separately to the extruder
In addition, powder-type materials tend to scatter and are sensitive to static electricity, making it difficult to apply in precise amounts and labor-intensive to handle

Abstract

Disclosed is a coating composition for automotive weatherstrips, in which inexpensive and easy-to-handle general-purpose polyolefin resins (i.e., HDPE with MI less than or equal to 1 dg / min and HDPE with MI greater than or greater than 20 dg / min) are used in the coating To prepare a film to protect the portion of the window glass run under pressure that contacts the window glass on an automobile door as the window glass moves vertically to open and close the window, the present invention provides economical benefits as well as the desired consistent performance.

Description

technical field [0001] This invention relates to coating compositions for automotive weather stripping. More particularly, the present invention relates to a coating composition for automotive weather stripping in which an inexpensive and easy-to-handle general-purpose polyolefin resin is used to prepare a film that is opened and closed when the window glass is moved vertically , to protect the portion of the window glass run channel that is in contact with the window glass on the vehicle door under pressure, thereby obtaining the economic benefits as well as the consistent performance required for the display. Background technique [0002] Generally, a window glass on an automobile door is configured to be opened and closed multiple times by vertical movement according to a user's intention. For this purpose, a window glass run is provided between the window glass and the window frame, which is a type of automotive weather stripping. The opening and closing of the window ...
