Product Description
Various of flooring are under application in the national economy and they can be divided to many types based on different properties. Epoxy and carborundum floor is commonly used for its high strength and low price. But it can be easily damaged under impact for its low toughness. To solve the short service life of epoxy self-leveling floor, STWD developed aliphatic polyaspartic polyurea floor top coating. It has excellent flexibility and abrasion resistance, high adhesive strength with any brands floor material.
Characteristics
High reaction activity, this coating has excellent fullness, tough, high compaction and shine gloss, with elastic and impact resistance, wearable and anti-slip. It has high properties of acid resistance, alkali resistance, anti- UV and weather resistance.
