We offer wide range of solvent based adhesives for a variety of applications that meets the needs of customers. The performance of solvent-based adhesives is largely determined by the polymer system in the formulation. The choice of adhesive type depends on the specific substrates and environmental resistance needed – temperature resistance, oil and plasticizer resistance, etc. Most solvent based adhesives contain flammable solvents which require proper precautions for safe handling. In addition, many organic solvents are regulated due to environmental concerns with emissions.

Within each type of solvent based adhesive, formulations are available to match the application requirements of the process – brush, roll, bead or ribbon, spray. Once the adhesive is applied, solvent evaporates relatively quickly causing an increase in viscosity of the adhesive film. Bonds can be made immediately after adhesive application or after some solvent has evaporated but before the adhesive has dried to the point where it will no longer wet (open time). Waiting for some evaporation prior to bonding (set time) increases the initial strength of the adhesive bond and allows assemblies to be processed more quickly.

Solvent based adhesives are a mixture of ingredients (typically polymers) dissolved in a solvent. As the solvent evaporates, the adhesive hardens. Depending on the chemical composition of the adhesive, they will adhere to different materials to greater or lesser degrees.

Contact adhesives are used in strong bonds with high shear-resistance like laminates, such as bonding formica to a wooden counter, and in footwear, as in attaching outsoles to uppers.

Natural rubber and polychloroprene (Neoprene) are commonly used contact adhesives. Both of these elastomers undergo strain crystallization.

Contact adhesives must be applied to both surfaces and allowed some time to dry before the two surfaces are pushed together. Some contact adhesives require as long as 24 hours to dry before the surfaces are to be held together. Once the surfaces are pushed together, the bond forms very quickly. It is usually not necessary to apply pressure for a long time, so there is less need for clamps.
