High Quality Adhesives – Desmodur RE / Isocyanate RE for adhesives CAS 2422-91-5 – Theorem Detail:
High efficient adhesive Isocyanate RE can alternate DESMODURE RE
Product details:
Chemical Name : Triphenylmethane-4,4′,4”-triisocyanate
Molecular Formula: C22H13N3O3
CAS: 2422-91-5
M.W: 367.36
Character: manufacturer
Structure formula: HC[ NCO]3
Density: 1.0g/c m3, 20℃
Melting point: 89℃
Our RE is a highly active cross-linking agent, Used in the adhesives made by hydroxyl polyurethane, natural or synthetic rubber, it has excellent bonding strength in rubber and cab be used in resin, antioxidant, plasticizing agent, pressure-sensitive etc. It can be used as crosslinker instead of BAYER’s Desmodur RE.
Two-component adhesive must be used within the applicaable period after putting in RE. The length of applicable period is not only related to the polymer content of adhesive, but also other relevant components(like resin, antioxygen, plasticizer, solvent,etc. When close to the applicable period, usually a few hours or one working day, adhesive becomes more difficult to operate, and viscosity rises soon. Finally, It becomes the irreversible jelly. 100 quality adhesive, Hydroxyl polyurethane (Polyurethane account for around 20%), RE dose 4-7. Chloroprene rubber (Rubber account for around 20%), Our RE does 4-7.
Packing:
750g/bottle, 20 bottles in one carton, 24 or 30 cartons in one pallet;
20kg/drum, 18 drums or 27 drums in one pallet;
55kg/drum, 8 or 12 drums in one pallet;
180kg/drum, 4 drums in one pallet
Storage:
Please stored in the original sealed jar under 23℃, the products can be preserved stable for 12 months. It very sensitive to the mosture; it will be produce carbon dioxide and insoluble urea in the reaction with water. If exposure to teh air or light, it will speed up color changes, but the practical function will not be affected.
