“…TC was used as a standard procedure for simulating the aging process [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. It utilizes the differences in the thermal coefficients of the expansion of the metal and acrylic resin, which induce stress in the adhesive bonding of various functional monomers contained in the utilized primers to the studied metal surfaces.…”

“…It has been also reported that the sulfur-containing monomers promoted the adhesion between the resin and pure metals, such as Au, Ag, Cu, and Pd [ 12 , 13 ]. The sulfur-containing monomers contained in commercially available metal primers were effective for improving the bond strength of resin to noble alloys [ 18 , 19 , 20 , 21 ]. However, particular types of the sulfur-containing metal primers that result in the most durable bonding between the resin and the metal elements of gold alloys still remain unknown.…”

This study investigated the effect of sulfur-containing primers for noble metals on the shear bond strength of self-cured acrylic resin after thermal cycling (TC). Four pure metals (Au, Ag, Cu, and Pd) and type IV Au alloy were either untreated, or treated with one of the five sulfur-containing metal primers (V-Primer, Metaltite, Alloy Primer, Metal Link Primer, and Metal Primer Z). Afterwards, a brass ring was placed on the metal surface and filled with self-cured acrylic resin (n = 10). The bond strengths were measured after 24 h (TC0) and after 2000 thermal cycles at 4–60 °C (TC2000). Three-way ANOVA and Tukey compromise post hoc tests were used to analyze the data (α = 0.05). All of the sulfur-containing primers significantly improved the resin bond strength as compared to that of the non-primed group at TC0 regardless of the metal type (p < 0.05). However, at TC2000, the bond strengths between the resin and the five metals significantly decreased with respect to the values obtained at TC0 regardless of the primer (p < 0.05). The sulfur-containing metal primers, except for Metal Link Primer, were found to be more effective for improving the bond strength between the self-cured acrylic resin and Ag as compared to the other three pure metals (p < 0.05). The bond strengths between the resin and Au and type IV Au alloy at TC2000 were the highest ones when Metal Primer Z was used.

“…Primers are capable of bonding nonpolar surfaces, and their use could be to increase the bond strength between adherends after surface treatment. 8,9 This primer must be able to penetrate into the leather grain layer increasing the cohesion of the collagen fibers and also, it has to be compatible with the adhesive. And primer was also applied to avoid roughening of leather and to improve adhesion and mechanical properties of adhesive.…”

Because of their low surface free energy and absence of polar groups at the surface, polyolefins are substrates whose wetting and adhesion are very difficult. Free radical grafting of monomers to backbone polymer is one of the most attractive ways for the chemical modification of polymers. Synthesis of graft copolymer through graft polymerizations of PE and/or PP with phthalic anhydride (PhAn) was made and FTIR spectra of the graft polymer were the examined. And also the effects of phthalic anhydride content on the grafting ratio, thermal properties and contact angle of the graft polymer were examined.
