TERPENE PHENOL RESIN

Terpene phenolic resins can also be added to solvent-borne CR adhesives to increase open tack time and to provide a softer glue line than /-butyl phenolic resins. To provide adequate hot bond strength, these resins are used in combination with a polyisocyanate curing agent. [Pg.664]

Terpene phenolic resins can also be added to polychloroprene latex without great reduction in hot strength as the resin content is increased, but contactability is reduced. However, an adhesion failure is obtained, even at the 50 phr level. Furthermore, terpene phenolic resins have relatively poor tack and impart the best... [Pg.668]

Terpene monomers are another class of interesting natural monomers because they give, on polymerization, hydrocarbon therplastic resins that exhibit a high degree of tackiness useful in pressure sensitive tapes [25]. They are also used for sizing paper and textile materials. Terpene-phenol resins are effective heat stabilizers for high-density polyethylene. [Pg.419]

Polymerization of terpenes using acidic catalysts such as AICI3 and BF3 is another major reaction for terpenes. B-Pinene and dipentene yield almost quantitative amounts of polymer in the 600-2000 MW range, while a-pinene yields only about 60% polymer in this range (32). More recently, it was claimed that an all a-pinene resin can be prepared by using chlorosilane as a catalyst (33). Monoterpenes condense with phenol in the presence of BF3 to form terpene-phenolic resins. [Pg.1173]

EVA copolymer compatibihsed with terpene-phenol resins (TPR) (165). [Pg.23]

Ethylene-vinyl acetate copolymer, terpene-phenol resins, polyethylene oxide, PMMA and some of their blends were solution cast on basic (aluminium oxide) and acidic (hydroxylated glass) substrates. Fourier transform infrared reflection absorption spectroscopy (IRRAS) was used to determine both the nature and the free energy of interfacial adduct formation in the polymer/metal systems. A correlation between IRRAS and adhesive strength may be used to predict both the acid-base work of adhesion and the density of interfacial interacting sites. 14 refs. [Pg.98]

The Desmocoll polymers show compatibility with some or all of the following polymers to the extent that they give clear solutions and films phthalic resins, xylene-formaldehyde resin, cyclohexanone-formaldehyde resin, highly chlorinated terphenyl, terpene-phenolic resin, acetyl cellulose, nitrocellulose, nitrile rubber, chlorinated PVC, vinyl chloride-vinyl acetate copolymer, rosin esters and coumarone resin. [Pg.234]

Terpene resins will be effective as solid solvents for an elastomer when their Hildebrand solubility parameters are close to the Hildebrand solubility parameters of the respective polymer. For example, from Table 22.4 it can be seen that pure polyterpene resins are suitable tackifiers for poly(ethylene) (PE), natural rubber, and polybutadiene polymers. Further, terpene phenol resins are suitable tackifiers for poly(vinyl acetate), poly(methyl methacrylate), and poly(ethylene terephthalate). [Pg.215]

Predominantly Midblock Compatible Resins. Aliphatic olefin derived resins, rosin esters, polyterpenes, and terpene phenolic resins derived from petroleum or terpentine sources and having relatively low solubility parameters tend to associate with the polydiene midblocks and not with the polystyrene endblocks. As the molecular weights or softening points of these resins are lowered, their solubility in the end-... [Pg.248]

The stability of Neoprene cements containing metal oxides could be increased with about 10 parts of hydrated calcium silicate, (e.g., Sil-ene EF, PPG Industries) or terpene phenolic resin (e.g., Durez 12603, Occidental Chemical Co.). The presence of the former increased the cohesive strength of Neoprene about threefold, while the latter lowered its cohesive strength at elevated temperatures. [Pg.285]

A tackifier is a component to provide initial tackiness to adhesives. The compatibility of the tackifier to the main components is very important to increase the tackiness without degradation of the adhesive mixture. For that purpose, natural resins such as rosin and dammar, modified rosins such as coumarone-indene resin, polymerized rosin, hydrogenated rosin and rosin ester, and polyterpene resin are used. Recently, alkylphenol resins, terpene phenol resins, and xylene resins are out of use because of their hazardous nature inducing sick building syndrome. [Pg.1013]
