Product Overview


3A 4A 5A 13X zeolite molecular sieve adsorbent powder as pastes in polyester-castor oil urethane floor to eliminate bubbles

Product Description


XINTAO activated molecular sieve powder is used to produce paints, varnishes, waterproofing and coatings based on polyurethane, polyurea, ceramics, epoxy, acrylic and PVA.

Activated Molecular Sieve Powder is dehydrated synthetic powder molecular sieve. With the character of high dispersibility and rapid adsorbability. It is used in some special absorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc. It can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin and some adhesives. It can also be used as desiccant in insulating glass rubber spacer.

The powder is also available as pastes (50% dispersion in castor oil). XINTAO zeolite powders and pastes are added to solvent-free one-pack and two-pack polyurethane systems, primarily to remove water. Applications include coatings, adhesives, sealants, casting resins, sports floors and elastomers.
