Wetting and dispersing additives help to reduce viscosity in highly filled foundry washes. DISPERBYK and DISPERBYK-192 are good products for foundry washes.
For water based foundry washes we recommend LAPONITE RD and OPTIGEL-CK. Both products will create a thixotropic flow behaviour in water based systems and improve the anti-settling. For solvent based foundry washes we recommend CLAYTONE-40.
BENTOLITE-L3 and BENTOLITE L10 are high purity aluminum silicates. Their high purity makes them very suitable for various monolithic refractory applications. They show good binding properties and high green strength.
