TRO is an industrial acronym most commonly referring to Tall Oil Rosin, a by-product of the wood pulping (Kraft) process. It is a cost-effective resin used similarly to gum rosin as a tackifier in adhesives, a sizing agent in papermaking, and a raw material for producing modified resins, printing inks, and soaps.
Key Characteristics & Benefits:
-
Economical Rosin Source: A lower-cost alternative to gum rosin from pine trees.
-
Good Tackifying Properties: Provides stickiness and adhesion in glue, tape, and sealant formulations.
-
Paper Sizing Agent: Improves water resistance and printability of paper.
-
Chemical Feedstock: Used to produce ester gums, modified resins, and surfactants.
