ALNOVOL® PN 650/60B

ALNOVOL® PN 650/60B by allnex is a bisphenol A- & F-free, non-self curing, o-cresol/formaldehyde novolak resin. It acts as a modifier of heat curable phenolic/polyester resin combinations (BADGE-free & BPA-NI systems), epoxy-free combinations and phenolic-/epoxy resin formulas. It has a very low free formaldehyde content of <0.1% and a very low free monomer content. An addition of 20-40% of ALNOVOL® PN 650/60B as solid on total dry film solid improves the flexibility of the coating by maintaining the chemical resistance. It improves leveling and substrate adhesion. It is compatible with high molecular weight epoxy resins of type # 7 and type # 9, polyvinylbutyral (PVB) and polyester resins like e.g. the food contact compliant DUROFTAL® grades. It is used for interior and exterior coatings of metal packaging goods like collapsible tubes, containers, cans and drums for water, oils and food. For this product, glycol ethers, esters, alcohols and higher ketones are suitable as solvents and diluents. And, aromatic hydrocarbons can be used as thinners. A recommended dosage is 1/3 of PN 650/60B as solid and 2/3 of the resole phenolic resin as solid. ALNOVOL® PN 650/60B has a shelf life of 365 days.
