Thermosetting Adhesive Based on Tannin and Poly(N-Hydroxymethyl Acrylamide)

A thermosetting adhesive consisting of tannin and poly(N-hydroxymethylacrylamide) was studied. This adhesive is an environmentally friendly one using only water as the solvent and is partly based on a natural product. It showed good bonding strength and water resistance for a wood product although those properties were lower than the level of phenol-formaldehyde resin.     

Factors affecting initial bond strength in solvent-based contact adhesives

Novel interpretation is given for the development of initial bond strength maximum in solvent-based contact adhesives at particular elastomer/resin ratios in the adhesive films. Complex relations between initial bond strength, tack of adhesive films, adhesive open time, solvent retention, and resin content in adhesive films are discussed. These results are based on data using polychloroprene adhesives modified with butylphenolic resins and also on previous studies with other contact adhesives. It is suggested that solvent retention is the main factor affecting initial bond strength in solvent-based contact adhesives.

Reduction of solvent content in toluene–neoprene adhesives and in acetone–polyurethane adhesives

The desorption of toluene in a polychloroprene (neoprene)-toluene adhesive and in a commercial neoprene adhesive was studied in air at three different temperatures by monitoring the weight loss vs time. Similarly, the desorption of acetone in a polyurethane adhesive and in a commercial adhesive was also considered. The experimental weight variations are correlated with the solution of the second Fick law at non-steady state. As the volume is highly reduced when the solvent is evaporated from the solvent-polymer mixture, the correlations obtained are discussed on the basis of the variation of the diffusivity with the solvent concentration, assuming that the product of the diffusivity and the polymer volume fraction to the power 2 is approximately constant. Apparent activation energies were obtained for the four adhesives used.

The effect of surface properties on the adhesion of modified polychloroprene used as adhesive

The adhesion properties of polychloroprene can be improved by addition of such materials as piperylene–styrene co-polymer (PSC), VeoVa-10 polymer, VeoVa-11/methyl methacrylate/2ethylhexyl acrylate co-polymer (VeoVa-11/MMA/2EHA) and poly(vinyl acetate) waste (wPVAc). Here, the relationship between adhesion properties and surface tension of polychloroprene was investigated. Contact angle measurements have been used to study the effects of nature and content of polymeric additives on the adhesion and surface properties of polychloroprene. Low-surface-tension VeoVa-10 polymer has the tendency to migrate to the surface of polychloroprene; thus, adhesion is determined mainly by this additive property. Enrichment of polychloroprene film bottom layer by the additive was observed using high-surface-tension PSC and wPVAc. In this case, the adhesion properties of polychloroprene depend on the interactions at the interface. Adhesion properties of polychloroprene were found to depend not only on compatibility between adhesive components, but also on compatibility between the adherend and the adhesive.

Behavior of adhesion forces of the aqueous-based polychloroprene adhesive magnetically conditioned

This research is an innovation proposal for magnetic conditioning of the aqueous-based polychloroprene contact adhesive with the purpose of increasing the adherence capacity between the adhesive and the substrate. Today, the aqueous-based polychloroprene contact adhesive presents an adhesion capacity variation between 1.15 and up to 2.75 kgf/cm². On the other hand, the solvent-based polychloroprene adhesives support average tensions of shearing of 3.8 kgf/cm². To promote an increase in adhesion to the aqueous-based polychloroprene contact adhesive, we formulated one adhesive using a nano-additive, carbon dioxide as catalyst, and a magnetic conditioning process before the phase of application on the substrates. The results obtained show an average increase of 292% in the shearing tension of the adhesive magnetically conditioned when compared with an adhesive of same formulation without the magnetic conditioning and when compared to the commercial aqueous-based polichloroprene adhesive, the increase reaches 122%.
