Liquid Sodium Silicate NSF Certified (Water Glass) Solution
Liquid Sodium Silicate, also known as Water Glass, is a multi-purpose alkaline sodium silicate solution with a variety of industrial, construction, ceramic, adhesive, and water treatment applications. This NSF grade sodium silicate solution is certified to NSF/ANSI 60 as a drinking water additive, with a maximum use dose of 265 mg/L. It has a SiO2/Na2O ratio of 3.20, a density of 41.1° Baume, and total solids of approximately 37.60%.
It is commonly used as a foundry-grade binder, ceramic deflocculant, carton adhesive-grade product, concrete and plaster sealer, and high-temperature bonding agent. It can also be used for surface applications, solid sand molds for metal castings, and wood treatment applications. Note that liquid sodium silicate is strongly alkaline, with a pH of approximately 11.3, and should be handled with proper care.

Applications and Benefits:
- Certified to NSF/ANSI 60 for drinking water treatment applications, with a maximum use dose of 265 mg/L.
- Used as a foundry-grade binder for instant solid sand molds in metal castings.
- Can be diluted to lower concentrations as required.
- Used in ceramic applications as a deflocculant to help prevent greenware shrinkage.
- Suitable for carton adhesive applications and other bonding uses.
- Can be applied to surfaces to create an instant antique look.
- Used as a sealer for plaster and concrete surfaces.
- Can be used as a wood treatment to improve water resistance and help deter insects.
- Functions as a high-temperature adhesive and bonding agent when applied in a thin layer between surfaces.
- Used in adhesives and binders, agriculture, cements and construction materials, detergents, drilling, geotechnical and mineral processing, manufacture of other chemicals, pulp and paper, textiles, and water treatment.
Caution:
Liquid sodium silicate is strongly alkaline, with a pH of approximately 11.3. Use care when handling this product and wear gloves and eye protection to help prevent skin and eye irritation or burns. Avoid contact with eyes, skin, and clothing. Use only as directed and determine suitability for the intended application before use.

Partially hydrogenated gum Rosin has a lighter color and is more stable.
Hydrogenated rosin has more resistance to oxidation and has lighter color.
Like unmodified pine rosin, hydrogenated rosin have a wide span of compatibility with almost all polymers. They are well known for their peel and tack contribution to the adhesive. Specific benefits of hydrogenated rosin include:
Lighter color.
Significantly improved stability.
Less to no skin sensitization (depends on the degree of hydrogenation).
Less UV absorption, thus making them suitable for UV curable polymer based adhesives.
Imparts only a slight decrease of cohesive strength, especially in block co-polymer systems.
Can be used in amorphous polyolefin based adhesives.
