Polyurea Spray For Sculpture Industry

Update::2022-07-12 15:10 View:
The qualitative effect of polyurea spraying has been widely used in the sculpture industry. Spray polyurea coating is solvent-free, fast curing and simple process. Can be easily sprayed on exterior walls and curved surfaces thicker than ten millimeters without sagging. Using this characteristic of it, many vivid and realistic artificial natural landscapes can be created, ranging from rocks and branches of various shapes, to whole rock walls or towering trees, even the small gravel on the rocks can be well washed copy. In addition, the use of a highly flexible formula can faithfully reproduce a tree that looks and feels like real bark, with no restrictions on size and shape, and is highly productive.
1. The on-site spraying construction sculpture prototype has good reproducibility, and the coating is continuous, dense and seamless:
2. The coating material has excellent mechanical properties and good elastic tear resistance, water resistance and impermeability;
3. The material has excellent construction characteristics.
