Developmental and technical information

Vanishing binder

Techpolymer IBM-2 is a methacrylic resin with good heat decomposition properties in a non-oxidative atmosphere. It can be used for binders that do not leave carbide when sintered. It has good solubility in a range of solvents, and the viscosity can be adjusted to suit your purposes.

n Description

Appearance White particles
Particle size 0.1 - 0.8 mm
Volatile matter (145 ºC × 1 hr) Not more than 0.5 % by weight
Glass transition point (Tg) 72 ºC
Molecular weight (Mw) 75 × 104
Solubility Soluble in organic solvents such as terpineol, MEK, and toluene.

n Heat decomposition properties

Heat decomposition of Techpolymer IBM-2

Decomposition of Techpolymer IBM-2 starts at low temperature, and decomposes completely at approximately 400 ºC.

n Solubility properties

Solubility in different solvents
(Ο: Freely soluble, Δ: Slightly soluble, ×: Insoluble)


Ceramic porous materials

You can use the spherical particles to form pores in a ceramic, selecting the particle size to suit your purposes. The pores can be adjusted as necessary given the particle size by mixing the Techpolymer and ceramic powder, molding, and burning.
