Valve exterior protection
| Product Name | Spray Polyurea Protective Material |
| Model Number | HTSPUA-4002 |
| Product Description | The coating system is composed of end-amine resin, aromatic amine chain extender and MDI prepolymer. It is a two-component, self-curing, thick-coating anticorrosion material. |
| Main Uses | External waterproof protection for polyurethane foam, EPS foam, rock wool fiber, perlite and other insulation materials; protection of lightweight thermal insulation roofs, large thermal insulation tanks, and thermal insulation pipelines. It solves the problems of corrosion resistance of the outer iron sheet of coastal tanks and easy peeling in typhoons, and solves the problem of easy leakage in pipe system patching. |
