An emulsion is a mixture of two liquids that cannot easily be combined. Oil and water is the classic example. Emulsifying is done by slowly adding one ingredient to another while simultaneously mixing rapidly. This disperses and suspends tiny droplets of one liquid through another.
Bio-based products have an alternative base wax or oil derived from nature, i.e. soy, tallow etc. that offer an innovative and sustainable options for our customers.
The addition of wax emulsion in the making of engineered wood such as MDF, PB or OSB provides dimensional stability and water repellency.
Walker offers a variety of wax products including 100% Petroleum based (paraffin) wax, Synthetic based (Alpha Olefin), Bio-based, Tallow and vegetable-based waxes, FDA approved waxes, and Emulsified (paraffin/synthetic, surfactant, water) waxes.
Yes. Our wax emulsions easily mix with PF (Phenol Formaldehyde), UF (Urea Formaldehyde), MDI (Methylene diphenyl diisocyanate) and pMDI (polymeric diphenylmethane diisocyanate) resins under normal operating conditions. Our technical group can recommend additional options for specific needs upon request.
Emulsions are susceptible to mechanical shear, because of this it is recommended to use a positive displacement pump with a hydraulically balanced diaphragm design, which are least harsh on emulsions.
Several manufacturers including Hydra-Cell are used industry wide to pump emulsified wax. When formulating an emulsion, our team can also tailor the formula to fit your particular equipment setup and needs.
Emulsions are stored between 5-30C (40-85F) in bulk tanks or tote bins with agitation at room temperature depending on the solids content of the emulsion. Do not store emulsion waxes below 0C/32F. More information on the proper storage and handling of emulsions can be found in each product TSDS and SDS. Our expert sales and technical experts can also provide best storage practices and recommendations dependent on your particular product.
Emulsions that are subjected to freezing break down and are no longer adequate for the designed use. When storage temperatures fall below 5C / 40F this may lead to product instability. As the products is thawed and heated (when previously frozen), the product may remain non-homogeneous even after
The TSDS and SDS for each product are supplied when purchasing. If you require additional copies, you can contact your sales representative or customer service and they will send the file requested.
