тиксотропный агент и Водный покрытия Чернила Добавить

thixotropic agent Outline: DB-AT enhances the latex paint the performance mechanism is DB-AT and the latex paint resin formation hydrogen healthy, in lowly reduces cuts the situation (storage condition) the system viscosity high, therefore guards against the subsidence, when the shearing force is high (brushes spreads) the hydrogen to strengthen is destroyed, the viscosity drops, therefore spreads brushes easily, after the shearing force vanishes, the viscosity maintains the low level by to help to flow evenly, then the rapid enhancement, guaranteed guards against the class to hang the performance. Is equal in Tilcom AT First, main performance: 1st, prevented in the pot subsides; After 2nd, spreads brushes flows evenly is good; 3rd, spreads brushes when drops few, guards against the class to hang; 4th, brushes spreads easily, the coating is thicker; 5th, in the pot the latex paint outward appearance is good; 6th, can help to enhance the varnish film to bear the period of five days and bears scours the nature. Second, DB-AT and other thixotropic agents compare merit: 1st, is insensitive to the latex paint system PH value change; 2nd, affects slightly to the latex paint glossiness; 3rd, easy to operate; 4th, versatility; Third, DB-AT in latex paint recruitment and increase method: 1st, DB-AT in the latex paint recruitment is 0.1 - 1.0%, the concrete recruitment decided by the test result, is 0.2% generally, does not surpass 0.5%; 2nd, the DB-AT application only then joins in front of the latex paint last working procedure - packing, stirs evenly then, wants to grind joins, otherwise is invalid. Fourth, ld-AT series test method: 1st, joins 1 - 2% DB-AT in 100 grams emulsion, stirs evenly, lays aside for 1 hour, the inspection viscosity whether sometimes does reveal the rise, if the viscosity does not have the distinct enhancement, explained DB-AT is not suitable for your firm the latex paint system; 2nd, takes 5 cups of latex paint each 100 grams, joins 0.1% DB-AT to stir separately evenly, the seal lays aside for 48 hours, the observation viscosity situation, and brushes spreads is flowing evenly, the anti- class hangs the performance, by chooses the best recruitment.
