SurfaPore R is a water based emulsion, composed of nanoparticles possessing three molecular regions: (a) The core nano-sized region, suitably engineered to fit the pores of a clay-based surface, (b) The hydrophobic moiety, attached on top of the core nanosized region, responsible for the creation of a continuous hydrophobic layer, and (c) The binding moiety, responsible for anchoring the nanoparticle directly onto the clay surface. 

Most traditional sealers are based on “plastic polymers” or small silicon based molecules (most often corrosive Potassium Methyl Siliconate, PMS) that react with atmospheric carbon dioxide to create a water barrier. Even though their action might initially appear effective, they detrimentally diminish the useful life time of clay based products by restricting their breathing ability or by creating efflorescence white spots. The use of such traditional sealers affects the three most important advantages of clay products: (a) their compatibility with modern construction requirements for breathable materials, (b) their endurance, and (c) their aesthetic perfection. 

NanoPhos introduces a new approach against covering clay surfaces with polymerizing additives. SurfaPore R coats the pores, the capillaries and the“free” surface with hydrophobic nanoparticles, protecting your favourite roof tiles while allowing them to breathe. The action of SurfaPore R nanoparticles is simple in conception, but extraordinary in use. Clay based materials expose their hydroxyl terminated surface to the deteriorating effects of weathering, UV radiation and water. Upon application of SurfaPore R, nanoparticles identify the hydroxyl groups and anchor on them. Anchoring is completed in 24 hours after application revealing the hydrophobic moiety of the nanoparticles. So, instead of suffocating your clay surface, we coat it with a hydrophobic dress!

Water Absorption: Results are based on laboratory testing of roof tiles samples provided by three independent roof tiles manufacturers: A, B & C. Water absorption is calculated after 24h of immersion in a water bath and expressed as %w/w: Manufacturer A, Without SurfaPore R:13,66% With SurfaPore R: 0,53%. Manufacturer B, Without SurfaPore R: 5,26% With SurfaPore R: 0,54%. Manufacturer C, Without SurfaPore R: 7,79% With SurfaPore R: 0,84%.       Stability under Ultra Violet (UV) Irradiation: Test samples were tested in a QUV chamber to evaluate direct sunlight stability and effectiveness. At least 10 samples were tested. Each treated sample was left to dry for 24h. Comparison was performed with the UK solvent based water repellent market leader. Contact angle is indicative for effective water beading and water exclusion:

ISO EN 1015-18 Capillary Coefficient Determination: Capillary Coefficient C (g/(dm2.min1/2))determination values are reciprocal to the water absorption ability. C values below 0.11 are considered effective water protection. Values below 0,07 have been achieved by surface application. 

Water Vapour Permeability Loss: Water Vapor Permeability was determined as the rate of water vapors “travelling” through a 2cm thick clay, roof tile sample. Vapor Permeability Loss:4,94% (surface application). 

Surface Application: The application surface should be dry and clean. Apply SurfaPore R by brush, roller or spraying. No dilution is required. On very absorptive surfaces re-apply within 3 hours. Dipping: Dip the clay based object in SurfaPore R for 30 seconds. In any case (surface application or dipping) test results on a small area before full scale application. Maximum water repellency is achieved 24 hours post application. Consumption: Estimated consumption rate 9-11 m²/L, strongly dependant on the properties of the surface applied.
