The mechanical stability, freeze-thaw stability and shelf-life of paints are all improved by the addition of surfactants. The addition of surfactants to paint also allow the paint to coat a surface more easily because surfactants increase the wetting of a solution. [4]
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer.It has the idealized formula [CH 2 CH(OH)] n.It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing.

IPBC was initially developed for use in the paint & coatings industry as a dry-film preservative to protect interior and exterior coatings from mold, mildew, and fungal growth, while also offering cost performance and sustainability benefits. IPBC exhibits efficacy against a broad spectrum of fungal species, typically at very low use levels.
Visible frost damage develops after an accumulation of micro-cracks as a result of several freeze-thaw cycles. [ 1 ] [ 2 ] Frost damage can be prevented by the use of frost-proof materials, i.e. , a material which has sufficient closed pores, by which the volume increase caused by the freezing of water in capillary pores can be absorbed by the ...
The Journal of Coatings Technology and Research is a bimonthly peer-reviewed scientific journal. It is owned by the American Coatings Association and published on their behalf by Springer Science+Business Media. The editor-in-chief of the journal is Dr. Mark Nichols (Ford Motor Company). [1]
Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl.

Initially the desired coating is applied in a puddle on the drawdown chart. Then the bar is placed at the top of the chart, and drawn down over the paint in order to spread it evenly along the length of the chart. Once this evenly spread paint dries, it can be tested for a variety of properties. [5]
