Here are some of the most frequently asked questions with their answers from Foundry and Refractory.
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.
