The raw material is used for the production of acrylic waterborne sealant for indoor joint filling.Building sealant is a paste building sealant composed of base adhesive, filler, curing agent and other additives.After impact, solidify into elastic rubber material and bond with building base material.It plays the role of sealing, waterproof and leakproof, and is mainly used for joint sealing of buildings.As a building adhesive, it is significantly different from other building adhesives such as glue in form and application. Other building adhesives are generally liquid and are mainly used for bonding and sticking building decoration materials without sealing effect.Due to the high price of silicone rubber, it used to be used for indoor filling, which increased the engineering cost. This type can be completely replaced to reduce the cost.The price of this sealant is different according to the requirements of different grades.It has the characteristics of high rebound, water resistance, low temperature resistance and strong adhesion
