Understand the function of foam EPC coating

Date:2023-07-10Visit:783

The main performance indicators of foam EPC coating are wet strength, dry strength, adsorption, suspension, permeability, film property and popularity.

1. Improve the strength and rigidity of the foam plastic film, prevent deformation and damage, and maintain dimensional accuracy.

2. Ensure that the gas discharged from the thermal decomposition of the foam plastic mold is discharged smoothly to prevent the casting from producing Casting defect.

3. Isolate liquid metal and sand mold to prevent liquid metal from penetrating into the molding sand, and obtain a smooth surface of the casting.

4. Using coatings with different thermal conductivity to control the cooling rate of liquid metal in the mold and improve the fluidity of the liquid metal. Foam EPC coating consists of refractory, adhesive, carrier, suspending agent, additive, etc.
