Molecular Sieve Paste

SuperSiv Molecular Sieve Paste

SuperSiv® Molecular Sieve PASTE is a convenient pre-blended zeolite paste, made from 50% SuperSiv® POWDER and 50% virgin Castor Oil.

It is used for the removal of water from within polymers, typically within 2-component Polyurethane formulations. It is also widely used for moisture scavenging in polyurea systems and zinc-rich paints.

By removing water from your polymer system, SuperSiv® prevents the formation of CO2 gas bubbles. This improves surface finish and structural strength of your final product.

At Baltimore, we always recommend 3A SuperSiv® PASTE for these applications, but we can also supply 4A SuperSiv® PASTE, if this grade is your personal preference.

[NB: If you already have the equipment to disperse micronized powders in your formula, then we encourage you to use SuperSiv® in powder format, a more cost-effective solution for large-scale users. For more information on this product, click here]
