ZINC POLYCARBOXYLATE DURELON Not as strong as zinc phosphate but is less irritating to the pulp. The mixed cement appears to be too thick but flows easily when applied to surfaces. The liquid reacts with the calcium in the tooth. (providing a stronger bond with the enamel, verses a weaker bond with dentin). Zinc Polycarboxylate provides chemical retention.

Zinc Phosphate Cement - an overview | ScienceDirect Topics

2.2.4.1 Zinc phosphate. Zinc phosphate cements have been used for decades, with high success rates. For this reason, they are the standard cement for assessing clinical efficacy. Although the cement does not offer either covalent or ionic bonding to the tooth, mechanical retention and high initial strength makes these materials suitable for cementing indirect restorations.

The zinc phosphate cement structure consists of excess zinc oxide particles in a non-crystalline, amorphous phosphate matrix. Crystals of hopeite (Zn 3 (PO 4) 2 ·4H 2 O) can grow from the cement surface if excess water is present. Extensive pores and surface layers of crystals, which are dependent on moisture conditions, affect the strength and adhesive properties of the cement.
