Researchers have examined polyols with bio-renewable content and their applications in thermoset coatings. In the present work, by combining unique features and functionalities of two low-cost commercial commodity bio-renewable based materials – epoxidised soybean oil (ESO) and rosin – polymeric polyols with bio-renewable content > 78 % by weight have been successfully developed.

Preventing ice accretion on exposed surfaces is important to the operational performance of various facilities and devices. As time elapses and temperature lowers sufficiently, ice accretion becomes inevitable. Herein, we present a new approach to prepare icephobic coatings by incorporating two strategies towards lowering ice adhesion strength, i.e. introducing an aqueous lubricating layer and maximising macro-crack initiators at the ice-substrate interface.

A highly stretchable and biodegradable superamphiphobic fluorinated polycaprolactone (PCL-b-PTFOA) nanofibrous membrane with a hierarchical porous surface was prepared via electrospinning. Solvent evaporation-induced phase separation and fluorinated segment migration are the major reasons for the formation of hierarchical porous surface. The introduction of fluorinated segments (PTFOA) greatly improved the superhydrophobic and mechanical properties of the nanofibrous membrane.

A facile preparation of flame-retarding coatings using aliphatic waterborne polyurethane as the binder has recently been described.

The mitigation of coating delamination is one of the important challenges for epoxy coatings under the cathodic protection. Scientists report the possibility to mitigate the coating delamination of epoxy coatings by inhibiting the hydrogen evolution reaction in the presence of thioureas. The wire beam electrode method, electrochemical impedance spectroscopy and traditional delamination test were employed to evaluate the mitigation efficiency in the work.

A new paper deals with a facile fabrication of environmentally friendly hygienic coatings based on acrylic latex comprising embedded inorganic nanoparticles originating from nanostructured ZnO and MgO, respectively, in the role of antibacterial agents.

UV and thermal dual responsive coatings have been developed based on benzoxazine/polyacrylate/mesoporous TiO2. The reversible surface wettability coatings have excellent comprehensive properties.

The Philippines’ historic achievement in the phase out of paints containing lead additives has been highlighted in the observance of this year’s International Lead Poisoning Prevention Week (ILPPW).

HP, one of the leading computer and printer brands globally, has maintained a positive outlook in the Philippines following strong demand due to work from home arrangements even as it strengthened its services to help in the students’ remote learning program of the Department of Education.
