产品名称:三丙二醇丁醚(DOWANOL* TPnB ) |
详细说明: DOWANOL* TPnB(三丙二醇丁醚) Tripropylene Glycol n-Butyl Ether Description A very slow-evaporating, hydrophobic glycol ether withoutstanding surface tension-lowering ability; ideal where highpolymer solvency and residence time are required Introduction DOWANOL* TPnB (Tripropylene Glycol n-Butyl Ether) is the slowest-evaporating member of the family of DOWANOL glycol ethers. DOWANOL TPnB is a high boiling, colorless solvent with low viscosity and practically no odor. Due to its length and hydrophobic structure, DOWANOL TPnB has a high organic solubility, low water solubility, and a high boiling point. Its unique properties make it suitable for a number of water-borne resins where a powerful coalescent is needed for proper film formation. Its solvating characteristics combined with low water solubility ensure that DOWANOL TPnB wil almost completely partition into the resin phase, thus providing superior coalescence. The extremely low odor of DOWANOLTPnB makes it suitable for indoor decorative paints. Physical properties Molecular weight (g/mol) 248.8 Boiling point @ 760 mmHg, 1.01 bar 274°C Flash point (Setaflash Closed Cup) 126°C Freezing point -75°C Vapor pressure@ 20°C — extrapolated < 0.01mmHg Specific gravity (25/25°C) 0.930 Viscosity (cP or mPa•s @ 25°C) 7.0 Surface tension (dynes/cm or mN/m @ 25°C) 29.7 Specific heat (J/g/°C @ 25°C) 1.80 Heat of vaporization (J/g) @ normal boiling point 2220 Net heat of combustion (kJ/g) — predicted @ 25°C 30.4 Autoignition temperature 186°C Suggested Applications Excellent solvent for heavy duty cleaners. Possible additive for floor wax strippers. Plasticizer in selected resin systems. Coupling agent and grease penetrant in oven cleaners. Solvent for inks in ball point and felt tip pens, stamp pads, and textile printing pastes. Coalescent for water-borne architectural and industrial coatings. Features High organic solubility Low water solubility Extremely low odor Superior coalescence Low viscosity High boiling point |
