1、 Material details 
After the sound absorption coating of the projection sound transmission screen of the cinema was improved by the AGG sound transmission polymerization technology, a more delicate projection sound transmission coating was formed after the physical fusion reaction of aluminate bonding particles with a smaller diameter of only 30 nm and modified polyethylene lotion, and special modulation. A projection sound curtain sound-absorbing coating with high temperature resistance, high viscosity, matte finish, and formaldehyde free properties.

2、 Material characteristics 
It can be attached to multiple basic materials to achieve projection sound transmission effect, and the image effect is better than traditional projection screens. The painting area is not limited, and the screen size and occasion are arbitrary. Simultaneously possessing sound absorption function, it has a regulating effect on indoor reverberation time and is suitable for home theaters, cinemas, exhibition decoration, conference rooms, large venues, and industrial applications. The material meets the A-level non combustible standard and E1 environmental protection level of China Building Materials Fire Protection Testing Center.
