Paraffin Wax Emulsion for construction board
Paraffin Wax Emulsion is a homogenous of stabilized dispersion of petroleum wax particles in water. It has the appearance of a milky near-white liquid. Paraffin Wax Emulsion has been designed as a hydrophobing agent for Particle board and Medium Density Fiber board (MDF) industries. It will have the best performance when applied separately from resin since it is not compatible.
For MDF, it can be applied to the system in 3 points i.e. at the blow line from refiner before resin that is preferred location, at the screw feeder or at the blender.
The dosing rate depends on the type of raw materials. The following rates are recommended for MDF
|Resin||Dosing rate (% wax on dry wood)|
|Urea Formaldehyde resin||0.55 - 0.85 %|
|Melamine-Urea Formaldehyde resin||0.65 - 0.85 %|
|Phenol-Formaldehyde resin||1.00 - 1.55 %|
|Solid content, wt%||58.0 – 61.0|
|pH||9.0 - 10.5|
|Viscosity 25 oC, # 2, 100 rpm (cP)||65 - 150|
|Density @15 oC, g/ml||0.930 - 0.965|
|Hard Water stability, ppm CaCO3||≤ 100|
