Coconut oil (CO) has become one of the most important renewable raw materials for polyol synthesis due to its abundance and low price. However, saturated chemical structure CO limits capability functionalization. In this study, a novel reaction mechanism via sequential glycerolysis amidation triglycerides produced an amine-based (p-CDEA). The synthesized biopolyol relatively higher hydroxyl value 361 mg KOH per g relative previously reported CO-based polyols with values ranging from 270-333...
The utilization of coconut diethanolamide (p-CDEA) as a substitute polyol for petroleum-based in fully biobased rigid polyurethane-urea foam (RPUAF) faces challenges due to its short chain and limited cross-linking capability. This leads compromised cell wall resistance during expansion, resulting significant ruptured cells adverse effects on mechanical thermal properties. To address this, novel sequential amidation-prepolymerization route was employed oil, yielding hydroxyl-terminated...
The immense growth brought by the global anti-corrosion industry translates into a massive demand for petroleum-based raw materials manufacturing these industrial products. Today, there is widespread popular support using renewable in coatings to break free from dependency on petroleum. This research focused develop bio-based polyurethane (PU) coating where corrosion performance of newly formulated soy-based PU with different concentrations nanographite deposited mild steels an aerated 3.5%...
This study propounds a sustainable alternative to petroleum-based polyurethane (PU) foams aiming curtail this nonrenewable resource's continued and uncontrolled use. Coconut fatty acid distillate (CFAD) crude glycerol (CG), both wastes from vegetable oil processes, were utilized for bio-based polyol production rigid PU foam application. The raw materials subjected catalyzed glycerolysis with alkaline-alcohol neutralization bleaching. resulting possessed properties suitable...

Mild steels were the most frequently used materials in industries and factories since it possesses unique properties but due to weak environmental changes, these cause deterioration corrosion materials’ surface. To prevent such, protective coatings applied protect against which by incorporating titanium nanoparticles polyurethane coatings. Titanium synthesized using butoxide as a precursor. The obtained an inhibitor mixed with coconut oil-based polyol blend on mild steel of 3.5% sodium...
Polyurethane has been used for years as an anti-corrosion coating due to its intrinsic hydrophobic properties. However, hydrophobicity is not enough inhibit the permeation of corrosive agents; thus, incorporating it with polyurea would further enhance In this study, coconut oil, a saturated, low molecular weight vegetable was employed eco-friendly precursor synthesizing novel poly(urethane-urea)- based hybrid coating. The synthesis process involved utilization oil-based polyol blend,...
Polyurethane coating has been widely used as a protective due to its wide range of mechanical strength, excellent abrasion resistance, toughness, low-temperature flexibility, and chemical simplicity in production application, superior protection on corrosion mild steel. No studies have reported utilizing coconut-based/PPG blend polyols produce polyurethane-based coatings Therefore, this work, we fabricated using for anti-corrosion application. Due low adhesion strength Polyurethane-based...
In this study, an eco-friendly coconut oil-based polyol blend was synthesized for bio-based waterborne polyurethane (WBPU) and WBPU-silane composite coatings. It demonstrated that increase in silane content incorporated into the WBPU matrix significantly enhanced corrosion protection of Results also show a fourfold adhesion strength coatings as compared to bare Further, water contact angle revealed hydrophobic properties increases. This work provides novel route utilizing blend.
Soil erosion, a global problem, degrades land quality and increases pollution sedimentation in bodies of water. This study propounds new material to mitigate soil erosion using rice straw-based polyurethane foam (RSPF) blocks as potential replacement for commercially available expanded polystyrene (EPS) slope stabilization. RSPF was synthesized via conventional one-shot foaming method with 15% polyol content. The have an average density 43.29 kg/m3, compressive strength 184.55 kPa, closed...
