Product Description

 

Polyurethane thickener

 

 It is a modified polyurethane thickener, which is a trend of perfect water-based non-ionic synergistic rheological modifier, excellent high shear viscosity distribution, both on the paint film internal water resistance, color extension and other properties, or the tank opening effect, smoothness and other properties outside the system, have very excellent performance. Polyurethane thickeners improve the rheological and leveling properties of waterborne coatings by improving high shear viscosity and inhibiting low shear viscosity, giving them a rheological energy similar to solvent-type alkyd coatings. Compared with the traditional water-based thickener, the thickening system is improved in terms of film formation, brushability, and apparent performance.
 Polyurethane thickener can be compatible with the base material commonly used in latex paint, and it has better water resistance and scrub resistance than the cellulose thickener. In the high-light emulsion paint system, using a polyurethane thickener gets a higher luster than using a polyacrylate or a cellulose thickener. This product is mixed with water and placed for several hours as transparent as water, is the ideal choice for transparent products!
It is a perfect supporting product of water-based products: we sincerely recommend the use of this product in high-grade internal and external wall coatings, and it can also be used in clothing printing, ink, color slurry, cutting liquid, plus 1% aqueous solution is slightly cloudy (the PH value of the use system: 3~10), with a shelf life of about 1 year.

Key Property
Low odor: Polyurethane thickener is a solvent-free polyurethane compound, according to a certain proportion of mixing evenly, can be directly used in the water-borne coating system.
 Improve the tank effect: improve the tank effect is the most characteristic excellent performance, does not affect the paint film smoothness, paint film thickness, can give the coating system is very beautiful tank fluidity: even if in easy to produce "false plastic" effect of vinegar c system, but also can give vinegar c system good fluidity.
 Excellent construction performance: polyurethane thickener in high shear viscosity (ICI viscosity) has a very excellent performance, after the construction of the paint film has excellent flow, smoothness, paint film rich, uniform.
 There is no adverse effect on the water resistance, gloss and color spread of coatings.
 Antimicrobial decomposition: the polyurethane thickener responds very poorly to the mycoid microorganisms, which can prevent the influence of most microorganisms on the system viscosity and ensure the stability of the system.
 By providing high shear viscosity and inhibiting low shear viscosity to improve the rheological and leveling properties of water-based coatings, giving water-based coatings the same rheological energy similar to the solvent type of alcohol acid coating, compared with the traditional water-based thickening agent, its thickening system is improved in the film forming, coating and apparent properties.
 Can be compatible with the base material commonly used in latex paint, compared with the cellulose thickener, the coating prepared with it has better water resistance and scrub resistance, in the high-light latex paint system, the use of polyurethane thickener than the use of polyacrylate or cellulose thickener can get a higher luster.
This product is mixed with water and placed for several hours as transparent as water, is the ideal choice for transparent products!

Water-based coatings, water-based building coatings, emulsified oils, concrete, water-based paints, printing coatings, ink, color paste, adhesives, cutting fluid, etc
Other water-based systems

Recommends Using Methods
Usage: 0.1-1.0%
Add method: press 1:1 or 1:3 mixed with water to stir evenly, in the paint production grouting stage or paint making stage slowly add.
Product matching: good compatibility with cellulose, alkali swelling and association type thickener.

Additive Amount
The added amount of polyurethane thickener depends on the rheological product composition required by the system, most of the added amount is 0.2-2.0%, and the best added amount depends on the specific situation.

Dilution method
Add to the pigment grinding slurry: can be mixed with other liquid components in the grinding slurry
During or after paint transfer stage: recommended after dilution with water or water / glycol mixture, recommended dilution ratio:

C-5	6%	10%	25%
glycol	-	35%	37.5%
water	94%	55%	37.5%
	100%	100%	100%
