The 10-2055 and 10-2055 HV were developed to produce a general purpose, semi flexible polyurethane adhesive for bonding a wide variety of plastic and metal substrates. The flexibility of these adhesives allows bonding to substrates with high coefficients of thermal expansion (CTE) and substrates with different CTE’s. The same Iso component is used separately with each Polyol at a convenient 1-1 ratio by volume. The selection of Polyol determines the initial viscosity of the adhesive. 10-2055 produces a light paste consistency similar to honey and 10-2055 HV produces a heavy paste consistency similar to grease. Please note each Iso and Polyol offer good low viscosity handling characteristics and turn thixotropic upon mixing.
