Susterra® Propanediol by Primient Covation is a pure, plant-based, petroleum-free diol. It is a non-toxic, food safe, renewably & sustainably sourced, 100% USDA bio-based building block. It exhibits high thermal stability and abrasion-, stain & scratch resistance. It is used as a co-solvent in water-based architectural- & industrial coatings and when used as polyol in PUD-s it helps improving adhesion, chemical-, corrosion & impact resistance as well as mechanical properties like resistance to deformation (Young’s modulus).<br>
<ul style="padding-left: 40px;"><li> In wood coating applications, it offers freeze-thaw protection & open time and prolongs durability due to higher initial elastic nature when formulated in PUD-s. </li>
<li>It is used as a solvent, humectant and as monomer for polyester binders (polyol) in inks, providing dry performance.</li>
<li>It improves flexibility & impact resistance, reduces viscosity when used to formulate epoxy polyesters for powder coatings, and is used as NPG replacement. </li>
<li> Susterra® Propanediol acts as an excellent monomer for polyol production or as chain extender in high-performing polyurethane applications. </li>
<li>It reduces solvents and provides grain enhancement & gloss in UV coatings. </li>
<li>It generates up to 86% less greenhouse gas emissions compared to 1,4-butanediol (BDO), a common petrochemical-sourced alternative and propylene glycol. </li>
<li>It can replace propylene glycol and boosts performance at both high & low temperatures. </li>
<li>It is suitable to formulate PUD-s for synthetic leather skin coats concrete floors-, electronics- & industrial direct-to-metal coatings.</li></ul>
