Polyurethane waterproof coating is a liquid construction of one-component environmentally friendly waterproof coating, is the import of polyurethane prepolymer as the basic ingredients, no tar and asphalt additives. It is the moisture in the air after contact with the curing, the formation of a solid layer on the surface of the solid tough seamless seams waterproof film.
(1) can be wet or dry on a variety of base surface direct construction.
(2) strong adhesion with the base surface, the coating material in the polymer material can penetrate into the base surface fine slit, follow the type of strong.
(3) the coating has good flexibility, the grass-roots expansion or cracking of the adaptability, high tensile strength.
(4) green, non-toxic and tasteless, non-polluting environment, no harm to the human body.
(5) good weather resistance, high temperature does not flow, low temperature does not crack, excellent anti-aging properties, can oil, wear, ozone resistance, acid and alkali erosion.
(6) coating dense, waterproof layer integrity, no cracks, no pinholes, no bubbles, water vapor permeability coefficient is small, both a waterproof function and gas barrier function.
(7) construction is simple, short duration, easy maintenance
(8) according to need, can be equipped with a variety of colors
(9) light weight, do not increase the load of the building Shelf life: more than 5 years;
Environmental protection: to meet GB 18582-2001 "interior decoration materials harmful substances limit" standard.
Is a unique formula from the modulation of the polymer, not only has a high bond strength, impermeability characteristics of good, without affecting the floor tiles, mosaic, wood flooring, gypsum board and other construction and installation.
1, the active ingredient in the slurry can penetrate into the cement surface of the microcracks produce crystallization, forming a dense waterproof layer. Able to cover small cracks, against a slight shock;
2, can be in the wet base surface construction, without mortar protective layer, you can directly paste the tile and other follow-up process;
3, the crystal depth into the substrate pores, impermeable compressive strength is high, with the water surface and back water surface waterproof function;
4, non-toxic, harmless, can be directly used for drinking pools and fish ponds;
5, the coating has the role of growth inhibition of mold, to prevent moisture on the surface of the pollution of salt.
1, indoor and outdoor concrete structure, prefabricated concrete structure, cement wiping, brick wall, light brick wall structure;
2, coated with paving stone, tiles, wood flooring, wallpaper, gypsum board before the substrate for the pre-treatment, to achieve the effect of preventing moisture and salt pollution:
3, basement, subway station, tunnel, civil air defense works, mine, building foundation.
1, the substrate must be strong, smooth, clean, dust-free, greasy, wax, release agent, and other debris;
2, before brushing the slurry, pre-fully wet the substrate, but can not have water.
1, use a hard brush, roller or shotcrete machine to mix the slurry evenly coated or sprayed on the wet substrate;
2, layered construction, the second layer of the brushing direction should be perpendicular to the first layer, in order to facilitate the best coverage effect;
3, the thickness of each layer of brushing can not be too thick, a coating thickness of not more than 1mm, in order to facilitate curing curing.
1, the construction temperature should be 5 ℃ to 35 ℃;
2, open the pulp after 1 hour run out;
3, in the waterproof layer on the paving tile recommended ceramic tile adhesive;
4, when used, do not in this product mixed with water or other materials;
5, the liquid component of the storage temperature can not be lower than 0 ℃;
6, before construction, please carefully read the construction instructions, in order to obtain reliable and satisfactory construction effect;
7, the construction, please use appropriate protective measures, such as gloves.
Implementation of standards and product quality level: GB / T23445-2009
Shelf life: in the normal storage, transport conditions, the shelf life of one year.
