Molecular Sieve Powder as Aluminum Honeycomb Panel Adhesive Glue Moisture Scavenger
Trace water is an important issue in the production and preparation of Polyurethane (PU) products. Trace water in polyols react with isocyanate to form carbon dioxide, resulting in foaming. At the same time, a large amount of heat is released, resulting in a shorter service life.
Chemxin activated molecular sieve powders are excellent moisture scavengers for paints, varnishes, waterproofing and coatings based on polyurethane, polyurea, epoxy, acrylic and PVA.
Chemxin Activated Molecular Sieve Powder is dehydrated synthetic powder molecular sieve. With the charater of high dispersibility and rapid adsorbability, it is used in some special adsorbability, it is used in some special adsorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc.
The powder is also available as pastes (50% dispersion in castor oil). Chemxin 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.
Molecular Sieve Powder for Aluminum Honeycomb Panel Glue Two-component Polyurethane Adhesive Production
The quality of the aluminum honeycomb panel is not only related to the selected material, but also mainly depends on the bonding quality, and its key technical index is the peel strength. The glue commonly used in the production and installation of aluminum honeycomb panels is polyurethane glue.
A small amount of molecular sieve powder should be added in the production process of polyurethane rubber products to ensure that polyurethane materials are in a state of low water content in different use environments.
