MINRO-SIL®
GROUT S15
General Information
MINRO-SIL® GROUT S15 is a silica-based, hydraulic setting material designed for application to the inside face of coreless
induction furnace coils in iron and non-ferrous melting applications. MINRO-SIL GROUT S15 should be applied in a uniform
layer of approximately ¼ inch thickness and may be worked between the turns of open coils for electrical insulation. Add
water to obtain good troweling consistency. Work with small batches of 25 pounds each. This product offers the following
benefits and features:
> Moderate set time
> Good surface finish and workability
> Can be used for straight or tapered grout jobs
It is recommended that minor repairs be allowed to air dry 4 to 8 hours before installation of the working lining. Major repairs,
or completely new coil coating, should be dried in accordance with Allied’s procedure CL-37.
