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.
Brand waterproof membrane of elastomer (SBS) modified asphalt is a kind of windable sheet waterproof material, which adopts styrene-butadiene-styrene (SBS) modified asphalt as a dipping and covering modifier, whose upper surface is coated by PE film, fine sand, mineral granules or aluminum foil, copper foils or other isolating materials.
Features
Spunbonded polyester fiber membrane;aintegrated advantage properties of spunbonded polyester substrates and SBS modified asphalt, wonderful integrated properties.
It could form waterproof layer, which has high strength and good property to stand against water pressure;
High tensile strength and elongation rate, strong adaptability for substrate shrinking distortion and cracks;
Good high and low temperature resistance, could keep its functions at -50; and be used in cold or hot areas, especially in cold areas;
Resistance to puncture, pressing and rubbing, tearing, and wearing;
Good resistance to corrosion, mildew and weathering;
Good construction performance, with firm and enduring joints.
Application Range
It could be widely used in all kinds of waterproof engineering projects in all fields, especially in the following types of engineering projects:
All kinds of building roofs engineering projects, exposed, non-exposed, heat preservation, non-heat preservation, planting building roofs and roof parking lots;
All kinds of underground waterproof or damp proof engineering projects;
Bridge surfaces of subways, tunnels, concrete roads, sewage treatment and garbage burying projects; water spraying pools, swimming pools, penstocks, water pools, and so on.
Yuhong Brand HCA-102 Acrylic Roofing Waterproof Coating is processed with 100% pure acrylic elastic emulsion as base material, mixed with high-grade pigment and varieties of carefully-chosen accessory ingredients. The product is excellent flexibility, bonding power and anti-ultraviolet radiation performance and applies to directly-exposed roofing waterproof project.
Features
100% pure acrylic elastic emulsion is base material.
Outstanding outdoor durability and anti-ultraviolet radiation.
Outstanding cohesiveness, applicable to steel structure base, cement mortar or concrete base, etc.
Durable low-temperature flexibility, crack-free bending under -30; low temperature.
Excellent elasticity.
Environmental water paint, pollution free.
Liquid state, cold process, safe and easy.
Application Range;
Apply to directly exposed roofing waterproof project.
Conformation Points;
Waterproof base: steel structure base, cement mortar or concrete base, internal and external angles should be in the form of circular arch, internal angle diameter should be bigger than 50mm, external angle diameter bigger than 10mm. For base cracks and grooves at the pipe end, sealing material should be filled and addition waterproof treatment should be made.
Film-coated waterproof layer: in case of multi-coating protection, thickness of each film coating should not be smaller than 1.5mm; for one-coating protection, thickness should not be smaller than 2mm. It can be separate film-coated waterproof conformation, and a layer of base reinforcement material can also be added according to actual engineering situation or design requirements.
Attention for construction;
Appropriate construction temperature is between, construction is not suitable in rainy days or there is water on the base.
Before hard dying of the film coating, waling on the waterproof layer is strictly forbidden, and protect it from damages.
