The size of its component will affect the softness and hardness of the PU coating; the hard segment is to make the PU coating have A certain strength and elastic modulus are mainly composed of various diisocyanates and chain extenders. The ratio of the soft segment and the hard segment and the types of raw materials can determine and affect the performance and use of the product.

There are many PU coating processing techniques: such as hot melt method, dry method, transfer method, bonding method, wet method, etc., the dry method is the most used one, and the dry method is actually to pour the coating slurry into The container is then evenly coated on the base cloth with an applicator.
