Halo's science mitigates the effect of solar radiation
Halo coatings are manufactured using a controlled chemical reaction in a reactor which ensures that its organic and inorganic components covalently bond into an integrated lattice matrix.
Conventional polymer coatings, especially those with high performance properties MIX organic polymers with inorganic additives in an attempt to leverage the desirable properties of each. They can be MIXED but they don’t really like each other and don’t “play well together”.
Halo does it differently with Matrix-Nano™ nanotechnology
Most conventional industrial coatings are based on synthetic polymers with extremely large organic molecules. Polymers provide adhesion, chemical resistance and flexibility. They are also susceptible to damage and degradation by exposure to sunlight. Energetic solar degradation creates ‘free radicals’ dangling electrons that can tear apart large organic molecules and change their chemical properties, usually in undesirable ways.
Solar Radiation creates free radicals.
An example of this process is how energetic solar radiation can create free radicals in skin cells, modify the large organic molecules in our cells, namely the DNA, and cause skin cancer.
As radiation-induced degradation occurs, the ability of a conventional coating to provide chemical an corrosion protection also degrades. This can cause whitening of the coating and de-lamination. To compensate, conventional polymer coatings will often contain a small percentage of inorganic material.
Halo coatings are the reverse of conventional ones.
They have a far larger proportion of inorganic oxides and our innovative process combines the best properties of those inorganic oxides (think of the properties of rock and glass) – their lattice structure provides strength, hardness, durability and UV resistance. After all, rock and glass are not much affected by solar radiation and have to suffer a significant impact before they break.
That inorganic lattice structure can allow brittle fractures along the lattice planes. Rocks, when they break tend to fracture along lattice lines. So the addition of organic polymer components in Halo coatings provide elasticity, tensile strength, chemical resistance and adhesion.
But unlike conventional polymer coatings, Halo coatings are not simply mixed blends of inorganic and organic components. Our unique process reorganizes the organic polymer chains and chemically bonds them within the inorganic lattice structure. A completely integrated lattice matrix results and retains the best properties of each while eliminating virtually all of her less desirable properties of the components taken individually.
And all this takes place at a nano technology level. Hence our name for the science – Matrix-Nano™.
Matrix-Nano™ allows Halo coatings to have the following properties:
a) be durable
b) have excellent adhesion – bonding and cross-linking to the substrate
c) be easy and convenient to apply
d) be environmentally sensitive
To expand –
(i) the high ration of inorganic to organic components results in an extremely hard surface.
(ii) using a classic measurement of material hardness, such as Ridgeway’s extension of the Mohs scale, a conventional polymer coating will have a hardness of 4 whereas Halo coatings range from 7-8.
(iii) Halo coatings resist methylene chloride solutions such as commercial paint thinners
(i) Halo coatings are thin and allow more surface contact between the substrate and the inorganic polymers embedded in the matrix
(ii) High cross-link density within the material itself improves corrosion and chemical resistance. High cross-link density from the coating material to the substrate improves adhesion and bonding
c) ease and convenience
(i) Most conventional polymers need to be combined with a catalyst to cure. So any excess mixed is wasted.
(ii) Halo coatings harden by air-drying
(iii) Second or multiple coats can be applied within minutes
(iv) Curing time is shorter than conventional coatings
d) environmentally sensitive
(i) Halo coatings contain less VOC s than the regulation minimum requirements set by California South Coast Air Quality Control Authority – the strictest in the USA.
(ii) Halo coatings contain no harmful isocyanate hardening agents. They literally harden and cure with oxygen and the moisture in the air.
