Developed and patented by USA-based Advanced Polymer Sciences (APS), Siloxirane is reported to be a multi-functional polymer which has a cross-linked organic-inorganic (SiO) backbone with oxirane end caps. When catalyzed, it results in an homopolymerized thermoset resin having an oxygen-to-carbon linkage with a very dense, highly cross-linked molecular structure.

According to APS the absence of problematic hydroxyl and ester groups eliminates the built-in failure modes of other polymers and provides superior anticorrosion and damage protection performance.

Siloxirane is believed to be resistant to 98 per cent of all corrosive acids, alkalis, solvents and fluids at various temperatures. In-house scientists and independent laboratories have conducted over 5,000 chemical and physical tests of Siloxirane resin and coating systems.

In applications testing of Siloxirane versus conventional coatings and materials such as vinylesters, high-build epoxies, zinc silicates and stainless steel, Siloxirane reportedly proved superior in virtually all performance aspects, as well as in economic cost comparisons.

APS also informs us that in addition to resisting an extremely wide range of acids, bases and solvents the cross-linked polymer structure of Siloxirane-based products eliminates permeation of the lining. This is thought to be a key benefit to the maritime sector, in which APS's Siloxirane-based MarineLine is extensively used, meeting chemical shipping tanker operators' needs for assured product purity and effective corrosion protection.

MarineLine also claims the advantage of versatility, by being able to handle different types of cargo without requiring a range of speciality coatings.

The adhesive strength and other physical characteristics claimed of Siloxirane polymer-based products means that they are highly resistant to "shock" temperature changes (from -40°C to +260°C), impact damage and abrasion.

Reinforced, composite Siloxirane lining systems are also available to meet even higher industrial application specifications, such as those required by ISO tank container operators for improved tank body protection against damage by substantial direct and reverse impact.
