  • Very good surface smoothness
  • Good strength and edge stability for its light density
  • Easy to seal and paint
 

Areas of Application

SikaBlock® M450 N is perfectly suited for manufacture of substructure for design, styling and clay models.
It is also recommended for manufacture of styling models and design studies. The product is also designed for manufacture of substructure for cubing and data control models as well as for short serie mold-making for composites parts by hand lay-up or vacuum infusion. This product is suitable for experienced professional users only. Tests under actual processing conditions and with additional materials such as coatings and release agents must be performed to proof material compatibility.

Application

Application Information

Application

SikaBlock® M450 N can be easily machined by milling, drilling, sawing or modified manually. It is recommended to use high performance tools to machine these boards.
For milling parameters check information from cutting tool manufacturers or get the General Guideline “Milling parameters for SikaBlock®” for more general information.

STORAGE CONDITIONS

The board needs to be stored flat over the entire surface in dry conditions.
Many models and tools are made of bonded boards, either with identical or other materials. Storage at low and elevated temperature can lead to high stresses due to the different expansion coefficients. To prevent this, it is necessary to store the models and tools at a temperature range between 15 °C and 30 °C.
