CASABOND™ 1201

CASABOND™ 1201 by Thomas Swan acts as an adhesion promoter. It can be formulated into systems based on natural rubber, SBR, BR, NBR, EPDM, CR and blends of NR/SBR, NR/BR and BR/SBR.

• It enhances adhesion to brass- and zinc-coated steel during vulcanization and direct bonding to textiles such as rayon, nylon and polyester, as well as glass and aromatic fibers.
• It improves handling, dispersion as well as reduces energy consumption and fuming.
• It requires the presence of a methylene donor such as hexamethylenetetramine (HMT) or hexamethoxymethylmelamine (HMMM).
• It is used in hoses (textile or wire reinforced-hydraulic/oil suction/ discharge hoses), belting (textile or wire reinforced-conveyor-/transmission-/ V-belting), tires (textile or wire reinforced-passenger/truck/aircraft tires (both cross-ply and radial)) and rubberized fabrics (protective clothing, tarpaulins, diaphragms with synthetic, woven fibers).
• Its recommended dosage level is 3.0-4.0 pphr along with 1.5-2.0 pphr of hexamethylene-tetramine.
• To improve further bond strength, 10.0-15.0 pphr of reinforcing silica can be added.
• CASABOND™ 1201 has a shelf life of 24 months.
