Now, it is mainly used in coating of water soluble PU system, adhesive and leather coating agent. Specification DMPA-Ⅰ (coarse) size 0.250-0.425mm ≥90%, DMPA-Ⅱ (refined) size 0.250-0.425mm ≤30% 0.150-0.250mm ≥50% Packing 　25Kg in paper-plastic laminated bag or cardboard drum. or following your　 　demands. Storage 　sealed, kept in cool and dry place. If piled, it should be laid on wood sheet 　with thickness of 10cm) and the distance from wall is 50cm.. Dimethylolbutanoie acid (DMBA) Molecular formula 　C6H12O4 Structural formula CH3－CH2－C(CH2OH)2－COOH Molecular weight 　148.16 Cas No. 　10097-02-6 Properties 　 odorless, free flow white crystal. Performance indicators Appearance White Crystal Content (%) ≥99 Water (%) ≤0.3 Melting point 108-115℃ Ash (%) ≤0.03 Residue Formaldehyde (%) ≤0.03 Acid Value (mgKOH/g) 374.7-378.3 Hydroxyl value (mgKOH/g) 728-782 Fe3+ (PPM) ≤5 Na+ (PPM) ≤150 K+ (PPM) ≤10 PO43-(PPM) ≤10 SiO2(PPM) ≤1 SO42- (PPM) ≤10 Acetone-Et3N Solube Experiment Transparent Uses It is a good crosslinking agent and hydrophilic agent, or used to produce water-based high molecule system, is widely used in water soluble PU system, polyester resin and epoxy ester. With good solubility, it also is widely used in coating of water soluble PU system, adhesive and leather coating agent.. It will become a new kind of environment-friendly substitute of 2,2-Bis(hydroxymethyl)propionic acid. Specification 　DMBA-Ⅰ size 0.250-0.425mm ≥90% Packing 　25Kg in Al-foil bag. or following your demands. Storage 　sealed, kept in cool and dry place. If piled, it should be laid on wood sheet 　with thickness of 10cm) and the distance from wall is 50cm..
