China State "863" project - Preparation of Nanometer Scale Polyacrylic Acid Based Emulsions for High Performance Water-Base Wood Coatings. Main constituent Acrylic copolymer Solid content (w%) 41-43 PH 5.5-6.5 Viscosity (mPa. S) 95-115 Particle size (nm) (TEM) <100 The minimum film-forming temperature (MFT)centigrade 40~42 Dynamic stability (2000rpm, 1hr) excellent These performance water-base wood coatings which products using this emulsion, have excellent performance like these: 1. Nontoxic, not have irritating odor, not contain dissociative TDI, VOC content is almost zero, unafire, real environmental protection. 2. High yellowing resistant, do not lose of gloss. 3. High solid content, film is full. 4. Good property, film is even and uniform. 5. High hardness, film is tough and abrasion resistant. 6. The construction function is good.
