Waterborne Polyurethane waterproof coating

Polyurethane waterproof coatings can be divided into one-component and two-component.
One-component polyurethane waterproof coating, also known as moisture-curing polyurethane waterproof coating, is a reactive moisture-curing film-forming waterproof coating. It is applied to the waterproof base layer during use and is cured to cross link into a tough, soft and seamless rubber waterproofing membrane by reacting with moisture in the air.
High-strength polyurethane waterproof coating is a two-component reactive curing waterproof coating. High-strength polyurethane waterproof coating Two-component chemical reaction-cured isocyanate-terminated prepolymer obtained by polycondensation of polyether and acid. Component B is composed of plasticizer, curing agent, thickener, accelerator, and filler. Composition of colored liquids. When used, the two components of A and B are uniformly mixed in proportion, coated on the surface of the waterproof base layer, and often cured by temperature cross linking to form a rubber elastic film with high elasticity, high strength and durability, thereby waterproofing.
The waterborne polyurethane waterproof coating generally refers to the one-component polyurethane waterproof coating, and the oily refers to the two-component polyurethane waterproof coating; in comparison, the water performance is almost the same, the price is also cheaper, the most important thing to look at the use environment! However, waterborne polyurethane waterproof coatings are more environmentally friendly.

One-component polyurethane waterproof coating is a kind of reactive curing film-forming polymer waterproof coating.It is made up of isocyanate and polyether as main raw materials, mixed with various additives such as solidifying agent and plasticizer, and is dehydrated and polymerized by high temperature.

One-component polyurethane waterproof coating, also known as moisture-curing polyurethane waterproof coating, is a reactive moisture-curing film-forming waterproof coating. When used, it is coated on the waterproof base layer, and cured and cross-linked into a tough, soft and seamless rubber waterproof membrane by reacting with the moisture in the air.

Product Description :
Yuhong SPU-301 one component polyurethane waterproofing coating is a kind of coating made by polymerization of isocyanate and polyether polyols, with addition of a variety of aids and fillers. It is applied on substrates to form a firm, soft, seamless sealing film by chemical reaction through, CNCO end group contacted with moisture in air.
Features;
It has one component which is easy to apply. The different types fits different applications.
It hasstrong adhesion, high strength and elongation, good elasticity, good high temperature and low temperature resistance, which make it fit to shrinkage and crack of substrates.
It has no benzene or coal tar, so it makes no pollution to environment.
Application Range;
It could be widely used in all kinds of moisture-resist and waterproofing projects, such as underground project, swimming pools, bathroom, balcony, parking lot and kitchen, as well as for non-exposed roof.
Construction Method;
Application Process: application preparation; substrate treatment and clean; additional waterproofing for details; application for roof; sealing of end joints and edge;application of protection or separation layers.
Substrate treatment: the substrate should be smooth, solid, clean, dry without sharp concave and convex, honeycomb, pocking marks, peeling free of bulge, greasy, apply sealant to concave around pipe root and do additional waterproofing layer in cracks.
Additional waterproofing layer: for details, such as concave and convex corners, pipe root, apply additional waterproofing layer, using type II to cracks, coat for 2;4 times(the thickness is about 1mm).
Apply waterproofing layer to roof deck: can coat for 2-3 times with scraper, but one coat is allowed too. When the first coat isnt sticky, can apply the second coat, the second coat should be vertical with the first coat. The batter coating rate is 2.0kg/m2for thickness of 1.5mm.

PU110 is one component polyurethane coat film with high durable elasticity designed for application on substrates ,which is chemical reaction with moisture in the air to form a soft and seamless sealing film.

Key Features
1. Pure polyurethane sealant, environment-friendly
2. Contains no asphalt, tar or any solvents, no harm to construction personnel
3. Free from pollution to the environment, no toxicity after curing, no corrosion to base material, high solid content
4. One component, convenient for construction, no need of mixing, surplus products should be kept in good airproof package
5. Efficient: high strength and elasticity, resistant to acid and alkali, excellent bonding effect with concrete, tile and other substrates
6. Cost-effective: the coating expands a little after curing, which means it turns a little bit thicker after cured
7. All items tested exceeds national standard GB/T19250-2003

Typical Applications
1. Waterproofing for basement, kitchen, bathroom, underground tunnel, deep wells structure and normal home decoration
2. Leak-proofing and penetrating-proofing of reservoirs, water towers, swimming-pool, for Bath-pool, fountain pool, impounding reservoir, sewage cleaning pool and irrigation channel
3. Used for preventing of leaking, corrosion and penetrating for water tanks, underground Pipeline
4. Bonding and moisture-proofing of various floor tiles, marble, asbestos board and so on
