PGDA(Propylene Glycol Diacetate)
--Eco paint solvent
PGDA(Propylene Glycol Diacetate)~is third generation of eco friendly high boiling point solvent launched by Zhuhai Feiyang Novel Materials Corporation Limited. Main feature: low odor, non toxicity, strong dissolving ability, good hydrophobicity and diester content(≥99%). As monoester is heavy hydroxyl content is ≤1% and low react activity.~PGDA can be applied in PU system. Besides, PGDA is called super eco friendly solvent, because of low Diester toxicity arise from propylene glycol replacing ethylene glycol. PGDA can replace DBE, cyclohexanone~in ink coating, baking coating and PU system. And can be coalescent agent for waterborn Coatings. Same as Dow PGDA.

1. Strong dissolving ability, hydrophobicity is prior to EGDA,bad activity with NCO, strong solvent for
polyurethane, alkyd, Crylic acid resin, polyester, Vinnolit, etc.
2. Non toxicity, low odor.
3. Can replace DBE completely to improve leveling, adjust film dry speed. Can replace cyclohexanone,
Isophorone, CAC, PMA, Butylcellosolve, etc high boiling point solvent partly.
Usage ratio in paint formulation 3-5%, usage ratio in thinner summer formulation 10-15%
Evaporate comparison: Butyl Acetate =1.0,PGDA=0.04,DBE=0.025, EGDA=0.05
Applying in PU, baking coating, ink coating, including coil coating, wood coating, can coating, auto coating,
NC paint, enamelled wire coating, screen print ink, cleaner, etc. Because of strong dissolving ability, slow dry and
good hydrophobicity, PGDA is prior to EGDA. PGDA is not recommended in single component plastic paint.
