CASABOND™ 1200

CASABOND™ 1200 by Thomas Swan is a blend of resorcinol and stearic acid in the ratio of 75:25 which 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 bonding to textiles such as rayon, nylon and polyester, as well as glass and aromatic fibres.
• CASABOND™ 1200 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.
• Used in hoses (Textile or wire reinforced- hydraulic / oil suction / discharge hoses), belting - textile or wire reinforced (Conveyor- / transmission- / V-belting), tyres (Textile or wire reinforced- passenger / truck / aircraft tyres (both cross-ply and radial)).
• It is also used in rubberized fabrics (Protective clothing, tarpaulins, diaphragms with synthetic, woven fibres).
• Its recommended addition 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 reinforcing silica can be added.
