The Jiangong brand environmentally friendly two-component non-tar polyurethane waterproof coating developed and produced by Ningde Xianggong Waterproof Material Technology Co., Ltd. in Fujian Province is a two-component chemical reaction curable waterproof material. Component A is a sealant obtained by polyether condensation polymerization. The end prepolymer, component B, is a colored liquid composed of plasticizers, curing agents, thickeners, coagulants, and fillers. When using, mix components A and B evenly in proportion, apply them on the surface of the waterproof base layer, and cross-link and solidify at high temperatures to form a waterproof coating film that is elastic, tough and durable. The research and development of this product has been included in the "Annual Science and Technology Project Plan" of the Fujian Provincial Department of Housing and Urban-Rural Development and is produced using national invention patent technology (invention patent number:). The technical performance indicators completely exceed the technical standards of B/"Polyurethane Waterproof Coating" . 【Product Features】
●Chemical reaction film formation, water-resistant, corrosion-resistant and cold-resistant.
●The waterproof coating film has high strength, large elongation and good elasticity.
●Can be applied thickly, with a dense coating film, no bubbles, and no pinholes.
●No benzene solvents, no coal tar components, no pollution to the environment.
●Liquid state, cold construction, convenient construction.
●Can be constructed on damp basement base surfaces. The base surface has strong adhesion and strong water impermeability.
[Scope of application]
Suitable for waterproofing on roofs and underground of civil and industrial buildings, municipalities, bridges, subways, dams, civil air defense and other projects. It can also be used in toilets, pools, balconies, parking lots, etc. Engineering waterproofing is more suitable for waterproofing construction of complex shapes and vertical and horizontal pipelines.
[Construction Technology]
●Basic base requirements: solid, flat, free of debris, fully dry, the inner and outer corners should be arc-shaped, the diameter of the inner corner should be greater than that, and the diameter of the outer corner should be greater than
●Ingredients and dosage: According to the construction dosage, mix components A and B in proportion, stir evenly and use.
●Large-area waterproofing construction: Apply the mixed paint evenly with a rubber or plastic scraper. The thickness must be consistent, usually ., and should be applied in 3 passes. The subsequent application should be cured after the previous application. After the film is formed, paint in a vertical direction. Weak links should be covered with carcass reinforcement materials.
●Coating film thickness: For underground projects, it should generally be ., and for toilet and bathroom projects, it should not be less than . When fortifying, the thickness of the waterproofing shall not be less than . The reference dosage of paint is: the dosage for thick coating film is about .3/, and the dosage for thick coating film is about ./.
●Construction of facing layer: Sprinkle clean sand on the surface before the last coat of paint is applied and solidified.
●Ending and edge treatment: additional coating for sealing.
●Protective layer: The surface of the coating waterproof layer should be isolated and protected according to the design requirements to prevent damage to the coating waterproof layer.
【Notes】
●The construction site must be ventilated. The temperature is generally above ℃ and is more suitable. Construction cannot be done on rainy days.
●There should be no open water on the wet base surface of underground projects, and construction should be done after it is drained.
●Waterproof coatings must be prepared and used on site. The prepared materials must be used up before solidification. The cured mixture cannot be diluted and reused.
●Before the coating film is dry, it is strictly prohibited to walk on the waterproof layer, and pay attention to protect it from damage.
●Attention should be paid to fire prevention at the construction site.
【Packaging, Storage and Transportation】
●The products are stored in clean, dry and airtight iron drums. The packaging of each group and B material are obviously different.
●The product should be stored in a ventilated, dry and cool place, away from direct sunlight. The storage temperature should not be higher than ℃.
●During transportation, prevent rain, exposure, squeezing, collision, and inversion, and keep the packaging intact.
●Under normal storage and transportation conditions, the storage period shall not be less than one month.
