Product introduction: AMMT-053 voice box protective material is the third-generation polyurea elastomer formed through on-site spraying of such raw materials as quasi-prepolymer, amine-terminated polyether and amine chain extender. As the revolutionary leap of the traditional construction technique, that technique organically combines the new materials, equipment and technologies, which is one of the most advanced construction techniques. Features: 鈼?100% solid content, no VOC, no pollution, green, environmentally protective and environmentally friendly. 鈼?nbsp;Fast curing speed, and no sagging under continuous spraying. 鈼?nbsp;Not sensitive to moisture or temperature, with good thermal stability. 鈼?nbsp;Good water resistance and protection performance. 鈼?nbsp;Excellent physical performance and good adhesive force to substrate. 鈼?nbsp;Excellent shock protection performance. Application: AMMT-053 voice box protective material is mainly used for the EPS and PUF foam protection, voice box, body, etc. which has excellent shock protection performance.

ColorIt can be adjusted in accordance with user requirement. Density1.01g/cm3 All the parameters mentioned above are the physical properties tested after 7-day curing after spraying by Graco H-XP3 host &Fusion AP spray gun under laboratory conditions. Drying time (25鈩? The surface will be dry within 2 minutes and can be off line within 10 minutes. Thickness: 1-2mm (depending on user requirements) Painting interval Minimum: no time limit; Maximum: not more than 3 hours. Substrate treatment: EPS and PUF substrate don't need any treatment. Before spraying, the substrate surface shall be clean without oil stain or impurities. Coating method: The high-temperature and high-pressure impact mixing equipment specified by our company must be used during construction. The loss caused by using the equipment not verified to be feasible by our company for the construction is at your own risk. Packaging specifications: Material A: 220kg/barrel; Material R: 210kg/barrel. The packaging can be changed in accordance with user requirement. Storage and transportation: This product shall be stored in the shady and cool, ventilated and dry warehouse, and rain, sun and fire source shall be strictly prohibited, while it shall be far away from the heat source, and the storage temperature shall be 15-40鈩? Under the condition of not opening the original packaging, the storage period of the product is 6 months since the production date, and if it exceeds the storage period, conduct inspection for the items specified by the product standard, and the product can still be used if it meets the technical requirements. The product doesn't contain organic solvent, so it can be transported as non-dangerous goods. The transportation shall be strictly prevented from rain and sun, and shall conform to the relevant regulations of the transport department. Labor protection measures: When using the product, it is required to wear labor protection appliances like work clothes, goggles, gloves and gas mask. Precautions: 鈼?During the construction, the substrate temperature shall be at least 3鈩?higher than the dew point. 鈼?nbsp;Fully stir component R until it is completely even before the construction. 鈼?nbsp;The unfinished coating material of component A shall be sealed after filling nitrogen. 鈼?nbsp;That system is 100% solid content, and the addition of any diluent is forbidden. 鈼?nbsp;Good ventilation shall be guaranteed during the construction in a confined space.Protective Coating factory website:http://www.ammtchina.com/protective-coating/
