Water-based polyurethane coating analysis.

Water-based polyurethane coatings
water-based polyurethane coatings are a new polyurethane system that replaces organic solvents with water as a dispersion medium. It has the characteristics of odorless, non-polluting, easy scrubbing, fireproof and explosion-proof, safe and reliable, and excellent mechanical performance. Water-based polyurethane has a very high adhesion to the substrate, cured paint film corrosion resistance, excellent chemical resistance, coating film shrinkage is small, high hardness, good wear resistance, excellent electrical insulation performance, with very high physical and chemical resistance . At the same time overcome the oily floor paint breathable shortcomings, providing a more durable service life and protection function. Water as a decentralized medium to save energy, non-polluting, and environmental protection requirements.
characteristics
water as a dispersing medium, does not contain toluene, xylene and other volatile organic solvents, will not create environmental pollution, no fire hazards, fire A (A1) level;
has excellent wear resistance, flexibility, scratch resistance, chemical physics performance,
can be constructed in a relatively humid environment, with reasonable curing time, to ensure that the coating film has a high cross-link density,
yellowing performance is excellent, oil resistance and moisture resistance is excellent, excellent adhesion effectively avoids the material's shell, bald layer and other phenomena;
form a high density, easy to clean, impact-resistant low shrinkage floor,
cured coating film gloss soft, excellent texture, and has good corrosion protection and one-way breath
ability; Drying time is fast, table dry 1h, do-it-do 4h (20-23 degrees C, relative air humidity 60-65%);
operation is good, construction tools can be washed directly with water, material storage, Transport and construction are safe and convenient.
use range

water-based polyurethane performance advantages
1, environmental protection: water as a dispersion medium, no pollution, solvent-free odor, will not cause environmental pollution, VOC content is low, in line with environmental regulations
; Polyurethane floor coating has a high hardness, ordinary type of water-based polyurethane floor hardness can reach 3 to 4H; Wear-resistant performance is better than epoxy floor paint;
3, super adhesion: water-based polyurethane has a very strong adhesion, can even attach to the surface of glass products;
4, excellent weather resistance: can withstand long-term solar exposure, strong UV resistance, not only for indoor and outdoor floors;
5, single-sided breathability: water-based polyurethane in the curing process occurred 2 reactions, one is a complex chemical cross-linking reaction is the process of water evaporation as a solvent, water molecules in the evaporation process, leaving micron-scale micro-pores, just like human skin, when the season changes or the temperature rises, the internal water vapor can be discharged through pores and the outside Moisture is not easy to go deep into it;
6, gloss adjustable: bright, semi-dumb, matte; water-based polyurethane can be adjusted between 10-90 degrees according to customer requirements;
7, color adjustable: coating appearance beautiful, water-based polyurethane can be based on national standard color cards, International standard color card, Raul color card and other colors to produce color paint, can also be customized according to the customer's sample color production;
8, oil-resistant, self-cleaning good: strong impact resistance, good stain resistance, anti-graffiti, easy to clean, in use is not easy to produce cracks, do not need waxing care, can be directly flushed, easy to repair and maintenance;
9, thin coating rate is wide: suitable for thin coating process, generally in 15-22m2/kg, can be self-leveling of epoxy, cement self-leveling, ordinary epoxy,
PVC and other ping play a role in surface protection;
11, with a certain flexibility: not only can provide excellent crack bridging, impact resistance and other mechanical properties, better protection of concrete, but also has silence, flexible foot feeling and other characteristics
