Phenol Formaldehyde (PF) Resins for Coatings and Inks

Rosin Modified Phenolic Resin 2116 by Foreverest Resources is the vacuum-treated product of esterification of glycerol (or pentaerythritol) with the polycondensate of rosin, phenol (or bisphenol A) and formaldehyde. Rosin Modified Phenolic Resin 2116 has high softening point and provides fast drying. It is soluble in tar, ester, turpentine oil and similar solvents. It is insoluble in alcoholic solvents, partially soluble in petroleum products and mix well with vegetable oils. Used in phenolic resin paints and texture printing inks.

ALNOVOL® PN 650/60B by allnex is a bisphenol A-, isocyanate-, and formaldehyde-free, non-self curing, o-cresol/formaldehyde novolak resin. It acts as a modifier of heat curable phenolic/polyester resin combinations (BADGE-free and 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.
• A recommended ratio 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 730 days.
