Tackifiers

Pressure sensitive adhesives, when in the dry state, are aggressively tacky at room temperature and possess a high degree of "quick stick" or initial grab. They can adhere to a variety of dissimilar materials without the need for much more than slight pressure. Often the pressure is applied by hand, but rollers, presses, and other mechanical devices can also be used. There’s always a scope for tailored performance for a particular high-end application. But, how to select the right additive for your requirement? Learn here, the additives and polymers that are used in pressure sensitive adhesives and how overall performance properties...

Thanks to the fast setting speed, relatively low cost (materials and processing), and low environmental impact, hot melt adhesives are widely used in applications (book binding, hygiene etc.). And like any other adhesive formulations, hot melt adhesives require a delicate balancing of constituents relative to the performance and processing properties. The selection of formulation components is determined primarily by the chemical compatibility of the components both during the formulation stage and during the service life stage. Optimal properties and performance can only be exhibited by a formulation where all the components are compatible. Become an expert by learning about:   » Basics...

Tackifiers are important constituents in adhesives formulations in order to maintain the correct balance between adhesion and cohesion. They must be considered with regard to the end-used properties, adhesive processing as well as compatibility with base polymer to achieve desired performance requirements. Get an in-depth understanding of the various classes of tackifiers and their mechanism, applications as well as benefits and limitations. Also, get tips to select the right tackifier for different polymers.
