Borealis Borcoat" BB122E-LT Polypropylene
Categories:	Polymer; Thermoplastic; Polypropylene (PP)
Material Notes:	Borcoat BB122E-LT is a maleic anhydride grafted polypropylene (PP) adhesive. The product is non-pigmented (not colored) and supplied in pellet form for processing via extrusion. Borcoat BB122E-LT has excellent low temperature impact resistance and contributes to an exceptional low temperature impact performance of the final coating. Applications: Steel pipe coating. Borcoat BB122E-LT is intended to be used as an adhesive in three-layer-PP based anti-corrosion coatings at design temperatures up to 110°C. The product is recommended especially when low design temperatures are expected. Borcoat BB122E-LT is intended to fulfill below mentioned national and international standards and specifications, when appropriate industrial manufacturing standard procedures are applied, a continuous quality system is implemented and when used in combination with a compatible Fusion Bonded Epoxy (FBE) powder and the top-coat material Borcoat BB108E-1199 or EB133E-1199-LT. Specifications: Borcoat BB122E-LT is expected to meet the applicable requirements included in the below mentioned standards provided it is processed using sound material handling and processing practices as well as appropriate testing procedures. DIN 30678 ISO 21809-1; DNVGL-RP-F106 NF A49-711; Gazprom 2-2.2-178-2007 Information provided by Borealis AG
