Zr44 complies with ASTM D4446 Standard for swelling of wood and Federal Specification SS-W-110c for water repellency.
Zr44 is a scientifically engineered, inorganic, solvent free, super-hydrophobic, penetrating water repellent that imparts superior water resistance to wood, giving it dimensional stability and protection against decay.
The major feature of Zr44 is its unique cross-linking mechanism, which locks the super hydrophobic materials into the pores of wood. As a result, the dimensional stability of wood treated with this system far outperforms wood treated with any of the leading water-based, or solventbased, organic products.
Zr44 is a non-film forming system that completely disappears into the pores of wood and does not provide a film to support the growth of mildew and bacteria spores. The net effect is, wood treated with Zr44 will not weather at near the rate of untreated wood or wood treated with typical organic stains and sealers. Zr44 is totally unaffected by UV exposure. Wood treated with Zr44 is also free from excessive cracking and deterioration caused by swell/ shrink cycles.
