CHEMPhenol Formaldehyde Resin
Phenol Formaldehyde Resin is irregular transparent solid and soluble in ester, gum turpentine, gasoline solvent, dry oil, etc. It's made from condensation of para-tertiary butyl phenol (p-t-butyl phenol) and formaldehyde under catalysis of calcium hydroxide. Due to its reactive methylol groups, it's most widely used in making polychloroprene contact cements that exhibit long open times and metal coatings. It's soluble Aromatic and aliphatic hydrocarbons, esters, ketones, and partially in higher alcohols. It's completely compatible with nitrile and polychloroprene rubbers. It has a compatibility limit of approximately 25 parts by weight in combination with 100parts by weight of SBR, natural, and reclaimed rubbers.
High quality paint, coating and adhesive agent & vulcanized agent of rubber products. It's extensively employed in the preparation of general purpose and heat-activating polychloroprene cements. It can also be used in formulating adhesives with NBR, SBR, natural and reclaimed rubbers.
