In another study, it was determined that pine and coniferous tannin species including higher amounts of resorcinolic type flavonoids and Pinus brutia might well result in a similar case. Pizzi reported that the Pinus brutia tannin gel-time was half-way between that of predominantly resorcinolic A-rings tannin such as wattle and that of a totally phloroglucinolic A-rings tannin such as Pinus radiate. The main properties of pine tannins have considerably fast rates of reaction with formaldehyde. Pine tannin has higher reactivity (10 to 15 times) than wattle and quebracho tannins leading to problems of resin potlife, and their higher degree of polymerization also leads to lower strength of their formaldehyde cured network [17].
