Data Sheet

01. Application

Dongwha Latex Free or mixed tropical hardwood MDF can be perfectly cut and edge-profiled. And due to the absence of rubber wood, the surface is free from latex spots. Aside from the smoothness of the surface, latex free surface provides an excellent base for numerous types of surface finishing such as spray painting, lacquering, veneering, paper laminating, etc.

02. Process

step.1- Crushing, step.2- Particles, step.3- Drying, step.4- Sorting, step.5- Coating, step.6- Molding, step.7- Pressing, step.8- Grinding, step.9- Cutting, step.10- Inspection, step.11- Shipment
