CERATHERM
(HOT BOX SAND BINDER SYSTEM)
Product
CERATHERM R-601 along with CERATHERM C-610 & CERATHERM S-620 is a specially formulated hot box binder system for sand moulds and cores for aluminium castings.
Applications
CERATHERM R-601 is a resin (binder) with furfural alcohol as co-polymer.
CERATHERM C-610 is a catalyst or hardener. It is a aqueous salt solution, mildly acidic in nature.
CERATHERM S-620 is a release cum moisture resistance agent.
The CERATHERM R-601, CERATHERM C-610 & CERATHERM S-620 are mixed as per below mentioned percentage with dry silica sand.
This prepared sand mix is blown into pre heated core box at 180–250°C. Due to heat from core box, resin & hardener from sand mix rapidly develops a bond to form core shape. The core is cured in the core box to develop handling strengths & is easily ejected from core box. Further Curing of core continues during the cooling of core.
