Siloxane polymers have demonstrated their ability, for more than forty years, to chemically-bond to aluminum and non-ferrous metal surfaces. Silicon Derivatives has taken advantage of this unique chemistry and has enhanced the breadth of application and performance characteristics of these very special and environmentally-compatible compounds.
Our Alumaclad™ product line incorporates a proprietary silicon polymer system developed to protect aluminum, copper, brass, and brass alloys from many forms of corrosion, and to prevent these surfaces from oxidation and tarnishing. Alumaclad™ produces a thin glass-like surface, highly resistant to a wide range of chemicals (see chemical resistance chart). Alumaclad™ also adds a thin, abrasion-resistant ceramic surface to naturally soft metals such as aluminum, copper, and brass, to protect from scratching and marring. In addition, Alumaclad™ is embedded with a silicon quaternary ammonium salt (a biostatic compound) to further inhibit the growth of microbiological materials on the coated substrate.
The Alumaclad™ blend of silanes couples methyl, phenyl and propyl polyorganosilanes to produce a low surface-energy, inorganic coating (high hydrophobicity). Water and solvent-based formulations employ differing rheology modifiers to assure coating efficacy (no pinholes, blisters, consistent flow characteristic, etc.) when applied to either vertical or horizontal surfaces.
Alumaclad™ is produced as a one-, two-, or three-part silicon system, either hydrolyzed in the field or pre-hydrolyzed at the time of manufacture.
Alumclad 3 Pak™ - a proprietary solvent-based, three-part, polyorganosilane polymer, which when catalyzed, produces an ultra- thin, glass coating, that may be applied on either horizontal or vertical surfaces.
Alumaclad 2 PakH™ - a low viscosity, solvent-based, Alumaclad™ polyorganosilane polymer that may be applied only on horizontal surfaces.
Alumaclad 2 PakV™ - a higher viscosity, solvent-based, Alumaclad™ polyorganosilane polymer that is limited to vertical surface applications.
Alumaclad 1 PakH™ - a low viscosity, water- based Alumaclad™ aminopolyorganosilane polymer that will catalyze under ambient conditions and which can be applied on horizontal surfaces.
Alumaclad 1 PakV™ - a higher viscosity, water-based Alumaclad™ aminopolyorganosilane polymer that will catalyze under ambient conditions and which can be applied on vertical surfaces.
Note: Some Alumaclad™ products are subject to US EPA AAIM VOC limitations, depending upon the carrier employed. Alumaclad™ contains no less than 5% nor more than 35% PCC's.
