What is Silane Siloxane Aliphatic? – The Innovative Product Technology

It is well known that heat can transfer from one medium to another through:

1. Radiation

2. Conduction

3. Convection

Heat typically enters a building via conduction and convection. There are three main ways to keep the interior of a building cool on a hot day: first, by imposing a thermal barrier (conduction) with conventional insulation materials like fiberglass and rock wool; second, by removing heat via increased convection using mechanical means like fans and blowers; and third, by enhancing heat reflection and radiation from roofs and walls back to the atmosphere.

Silane Siloxane Aliphatic was developed based on the third principle, using specially selected pigments in the membrane. This makes the surface an excellent reflector of solar radiation across the full spectrum, from ultraviolet to visible to near-infrared, and a good radiator of far-infrared. Silane Siloxane Aliphatic is India's first heat-re-radiating coating, effectively utilizing radiation to achieve its insulating effect.

Independent studies on Silane Siloxane Aliphatic show that it reflects 85% of incoming solar radiation back into the atmosphere and re-radiates up to 14%. These tests demonstrate that the insulation effect is not dependent on the coating's thickness and is effective with a minimum thickness of 100 microns. Thus, insulation is achieved through surface area via reflection and re-radiation of heat back into the atmosphere, rather than using thick materials as in conventional systems. Once applied, the coating continuously reflects and re-radiates heat, rejecting more than 95% of the heat, with only a small percentage penetrating into the building or installation.

Surface Preparation

All surfaces must be clean and dry before applying Silane Siloxane Aliphatic. The surface must be free from large contaminants and structurally sound. Preparation can include high-pressure water cleaning, oil-free compressed air, and the removal of mold and fungus. This process helps kill and remove any mold. Any necessary structural repairs should be made, and the surface should be clean and sound. Apply one coat of Silane Siloxane Aliphatic and allow it to dry before applying the second and final coat.

Application Procedure

Silane Siloxane Aliphatic can be applied with a brush or roller for standard painting. Use a 1" to 4" brush for application, or a roller for relatively smooth, dense masonry surfaces. The amount of coating needed will depend on the surface’s porosity, texture, and the number of coats required.

Drying Time

The coating is touch-dry in less than one hour with minimal dirt pick-up. For optimal performance, wait 24 hours between coats.

Roofing Application

First Law of Thermodynamics: Energy is conserved; it is never lost. "What goes in must come out."

Second Law of Thermodynamics: Energy is conserved; it is never lost. The issue is the flow of heat in the building and the temperature inside.

Modes of Heat Transfer:

1. Conduction

2. Convection

3. Radiation

Radiation is of particular interest because we are the only company offering insulation for radiated heat, which accounts for 60-70% of all heat transfer. Conventional insulations only address the first two modes of heat transfer.

Application on Tanks for Better Roof Insulation: Cypruss Coating offers the best solution for high solar reflectivity, high thermal emissivity, and solar radiation absorptivity. Most building materials have a reflection of 0.2, an emissivity of 0.2, and an absorptivity of 0.8. This means that the solar heat observed by these materials is not emitted back effectively, and Cypruss Coating solves this issue.
