CASABOND™ 1202 by Thomas Swan acts as an adhesion promoter and 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 improves handling, dispersion as well as reduces energy consumption and fuming.
• 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 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), tyres (textile or wire reinforced- passenger/truck/aircraft tyres (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™ 1202 has a shelf life of 24 months.

Fine-Blend® CMG9801 distributed by DKSH is an adhesion promoter. It is a maleic anhydride modified polypropylene with excellent long-term thermal-aging property. It can provide excellent adhesion between PP and polar substrates such as glass, metal & minerals and high reactivity with some chemical groups(-NH₂, -OH).

• It can be processed over a wide range of conditions.
• The typical processing temperature range is from 180°C to 280°C.
• Fine-Blend® CMG9801 is suitable for fiber glass reinforced & mineral filled PP compounds, PP based WPS and alloys, especially in aging-resistant composite material system.
• It is available in Europe, North America and Asia Pacific.
