The ZOE impression paste is essentially a two-paste ZOE cement. One paste is formed by plasticizing the zinc oxide powder with 13 % of mineral or vegetable oil. The other paste consists of 12% eugenol or oil of cloves, 50% polymerized rosin, 20% silica filler, 10% resinous balsam (to improve flow) and 5 % calcium chloride (accelerator). 

Tolu balsam, a plastic solid, is derived from a related tree in Colombia. Its uses are similar to Peru balsam. Source of tolu oil. Odorless. 

Both the terms resin and plastic are in common use but there are no explicit definitions for them. The term resin originally referred to vegetable-derived organic products of relatively high molecular weight, the best known of which are rosin and balsam obtained from coniferous trees. But, the term is now used much more broadly, and rather loosely, to include the manmade polymeric substances used in a variety of applications, such as in plastics, textiles, and paints. It is often used interchangeably with the term plastic . 

Rosin family s most common form of adhesive is colophony, a hard amorphous substance derived from the oleoresin of the pine tree. This material is applied in solvent solution form as a hot-melt mastic. It has poor resistance to water, is subject to oxidation, and has poor aging properties. Plasticizers are usually added to reduce its brittleness. Bond strengths are moderate and develop rapidly. These materials are used as temporary adhesives in bonding paper and as label varnishes. They are also used as components of PSAs based on styrene-butadiene copolymers and in hot-melt adhesives and tackifiers. These materials have been largely replaced by synthetic-resin adhesives. One specialized form of rosin adhesive is Canada Balsam, covered by the obsolete Military Specification MIL-C-3469C, titled Canada Balsam. This material was intended for cementing optical elements.

Balsam tolu is obtained from the tree trunk of M. balsamum by making V-shaped incisions through the bark and sap wood. The liquid balsam is collected in gourds and solidifies on aging. The balsam is a plastic solid with a brown or brownish-yellow color that darkens and hardens on aging. Like halsam Peru, it is a true balsam. Tolu balsam has an aromatic vanilla-like odor and an aromatic, mildly pungent taste it is insoluble in water but soluble in alcohol, acetone, benzene, and chlorinated hydrocarbons.
