Orbolite in coatings


Cenospheres in ceramic ware and resins have proved their qualities time after time, producing a lighter weight, improved impact resistance and thermal resistance than the solid ceramic mix.

Enhancing coatings, resins & polymers

ORBOLITE® cenospheres transform coatings, resins & polymers to superior products with enhanced performance.

Paints and Coatings

Cenospheres are becoming more and more popular for finished coatings. Due to their spherical shape, hollow interior, lightweight, low density and hard endurance, they are ideal, for a number of applications from industrial flooring to marine deck paints and varnishes (anti slip).

Their usage has risen steeply lately. With the concerns about the environment the use of cenosphere in coatings and paints can act as a heat loss barrier and an erosion barrier against the harshest weather conditions. Once applied along with having a thermal insulating effect this coincides with it anti condensation properties putting up a defence against cold spot crossing.

A more recent development with the discovery of volatile organic compounds (VOC) content and the need to reduce them. Our finer grades Orbolite 106 as a corrosion resistant coating, the conventional method of aligning plates and pallet fillers which is costly and time consuming by applying a coating of fine cenosphere (Orbolite 106) they would naturally form a dense barrier reducing any risk.

Also we have had a range of our cenospheres measured for radiative properties to see if they comply with ASTM E903 Total solar reflectivity, ASTM C1371 Thermal emissivity and ASTM E Solar Reflectance index.

Last but not least paint technology has taken cenospheres to its heart as they can produce an attractive finish.

Resins & Polymers

From car body putty to resin transfer moulding ORBOLITE® has multiple benefits. For example, many industries now require that with any new design or replacement part (where compatible) should be replaced be an eco-friendly replacement. On area leading the way in this is the automotive industry, their requirement to reduce weight has brought the use of cenosphere into applications ie Sheet moulding and Dough moulding compounds where their addition has reduced sag, increased shrinkage control, made easier for polished smooth surfaces and ease of use. Applications have been multi fold, wind deflectors, under bonnet parts, body shaping parts, bumpers, sunroof frames and many more.

Low Pressure Moulding Compound (LPMC): Due to the spherical make up cenospheres natural fluidity makes it ideal to be pumped under low pressure. The low cost composite tooling employed in this area utilises cenosphere in the back up moulding process. Polymer concretes used in a vast variety of areas i.e. pipes, decorative mouldings moulded plastic boxes to name a few.

In Brief

  • Low density reducing slump and sag.
  • Good thermal insulation.
  • Rheology show brilliant results. Great flow at high volumes.
  • Cenospheres have the lowest surface area to volume ratio which leads to a high volume loading, compared to other fillers.
  • Due to the hard outer shell once formed and cured cenosphere exhibit good practicalities, can be cut, sawn, nailed, sanded milled ( See data sheet) and exhibit excellent impact resistance.
  • The final products have a low density making them easier to handle and transport, important in transportation applications such as marine, automotive, aerospace and beyond, resulting in fuel economy, higher speeds, improved buoyancy etc.
