Environmentally friendly PU pure polyurethane waterproof coating

High-performance, high-strength and high-elongation environmentally friendly polyurethane waterproof coating is an annual Fujian Provincial Department of Housing and Urban-Rural Development Science and Technology Plan project undertaken by our company - Fujian Ningde Xinjian Gong Waterproof Material Technology Co., Ltd. It is based on the structural durability requirements and structure of the high-speed rail passenger line Characteristics and the demand for waterproofing in high-level construction projects, a two-component, high-strength, solvent-free special waterproof coating developed using the latest scientific research results in polyurethane production. All performance indicators meet or exceed the "Passenger Dedicated Line Bridge Concrete Deck" The technical requirements of "Interim Technical Conditions for Waterproof Layer" (Science and Technology Basic Letter No. []) and National Standard B/"Polyurethane Waterproof Coating" have achieved the unification of the high strength, high elongation and high solid content properties of polyurethane coatings. According to different uses, the waterproof coating is divided into two types: waterproof coating (3.) used for pasting waterproof membranes and waterproof coating (.) used directly as a waterproof layer. The technical performance indicators comply with the Ministry of Railways' "Interim Technical Conditions for Concrete Deck Waterproof Layers of Passenger Dedicated Line Bridges" (edition). [Product Features]
●It is an environmentally friendly product. The product strength can reach . In particular, it has high strength and extensibility, and has strong adaptability to cracking or expansion of the base layer
●High strength, high wear resistance, impact resistance, resistance to chemical media corrosion, high bonding strength, wear resistance, mud and sand resistance Wash by other media
●The product is easy to construct. During construction, you only need to mix components A and B in proportion, and then brush or spray it on the waterproof base layer. It is a cold-construction waterproof coating
●Easy to maintain. , only need to partially repair the damaged parts to achieve the original waterproof effect, saving time, effort and low cost ●The color is adjustable to meet your color needs.
[Scope of application]
●The product is suitable for waterproofing and anti-seepage of roadbeds, bridges, tunnels, and culverts on high-speed railway lines with speeds above kilometers/hour
●Water conservancy and hydropower engineering dams, reservoirs, transmission Waterproofing and anti-seepage of water tunnels, bridges and culverts
●Waterproof and anti-seepage of roofs, basements and sports venues of important buildings
●Waterproofing of overpasses, overpasses, viaducts, etc.
●Drinking water pools, swimming pools, Waterproofing of sewage treatment pools
●Internal and external waterproofing and anti-corrosion of pipes and metal equipment in various industrial and mining enterprises
●Various cracks and caulking bonding and sealing.
[Construction Technology]
●The base layer must be strong, flat, free of debris, and fully dry. The inner and outer corners must be arc-shaped, with the diameter of the inner corner being greater than 1, and the diameter of the outer corner being greater than
●Ingredients and dosage: According to the construction dosage, mix components A and B in proportion, stir evenly and use. The reference dosage is: the dosage for thick coating film is about .3/.
●Large-area waterproofing construction: Apply or spray the mixed paint evenly with a rubber or plastic scraper. The thickness should be consistent, usually . After the coating is cured to form a film, it is painted or sprayed in a vertical direction. Generally, a separate film is formed. An additional layer of matrix reinforcement material should be laid on the underground engineering floor.
Coating film thickness: For subway projects, it should be ., for underground projects, it should generally be ., and for toilets and baths, it should not be less than . When fortifying a III roof, the waterproof thickness shall not be less than .
Protective layer: The surface of the coating waterproof layer should be isolated and protected according to the design requirements.
[Notes]
●The construction site must maintain good ventilation, fireworks are strictly prohibited, and no construction is allowed on rainy days
●If the material is found to be precipitated, it should be stirred evenly before use
●Paint should be prepared for immediate use and used up within minutes
●If the coating film is damaged at the construction site, use a cutter to dig around the break, then paint and repair it with waterproof paint.
[Packaging, Storage and Transportation]
●Component B is packed in iron drums, with a net weight of 3 per group. There is a clear difference between the outer packaging of material B and material B
●Keep the material in a dry and ventilated place Indoors and during transportation, be strictly protected from the sun and rain, prevent collisions, and pay attention to fire prevention
●The product storage period is one year. After the storage period, it must be re-inspected before it can be used.
