Selecting Plasticizers for Adhesives and Sealants
Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants. However, the addition of certain plasticizers to a polymeric emulsion will usually result in increased viscosity. This effect can be used to formulate a waterborne adhesive having greater coating thickness build-up.
Pressure-sensitive adhesives (PSA) - ExxonMobil Chemical
Pressure-sensitive adhesives (PSA) based on Escorez tackifying resins are capable of holding materials together by instantaneous low-pressure surface contact. Most commonly, a PSA is based on selected elastomers that are modified to enhance tackifying and wetting properties. These products require no activation by water, solvent or heat to
Hot Melt Adhesives: Ingredient Selection & Formulation Tips
The most common general-purpose hot melt adhesive is based on ethylene vinyl acetate (EVA) resins. These are used in the packaging, furniture, bookbinding, and footwear industries. For pressure-sensitive hot melt formulations, the base polymer is often a block copolymer, such as styrene-isoprene-styrene (SIS) or styrene-butadiene-styrene (SBS).
Pressure Sensitive Adhesives in EV Batteries: 5 Questions to
Consistent quality relies on how pressure sensitive adhesive (PSA) is handled from the melter to the applicator or nozzle. Hot melt equipment with closed loop control can assure that the material stays at the desired temperature and viscosity for ideal dispense.
Plasticizer resisant hot melt pressure sensitive adhesive
Improved plasticizer resistant pressure sensitive hot melt adhesive compositions are prepared by incorporating in the adhesive polymer, tackifying resin and oil 5 to 70% by weight of...
- What is a pressure sensitive adhesive?
- Pressure sensitive adhesives are a type of non-reactive adhesive which forms a bond when pressure is applied to bond the adhesive with a surface. No solvent, water, or heat is needed to activate the adhesive. Surface factors such as smoothness, surface energy, and removal of contaminants are also important to proper bonding.

- What is a rubber-based pressure sensitive adhesive?
- Rubber-based pressure sensitive adhesives are designed to help optimize coater line speeds. They provide high tack while balancing adhesion and bonding for use in a number of industrial applications. Our rubber-based pressure sensitive adhesive range offers products that are easily removable as well as adhesives for permanent bonding options.
- Does pressure sensitive adhesive need a solvent?
- No solvent, water, or heat is needed to activate the adhesive. Surface factors such as smoothness, surface energy, and removal of contaminants are also important to proper bonding. Pressure sensitive adhesives are designed to form a bond and hold properly at room temperatures.
- What is Henkel water based pressure sensitive adhesive?
- AQUENCE ® PS, Henkel’s range of emulsion-acrylic pressure sensitive adhesives, is used across many industries. The adhesives are coater-ready and provide advanced bonding and excellent results. Henkel water-based pressure sensitive adhesives are commonly used to manufacture products such as:
- What are emulsion-acrylic pressure sensitive adhesives?
- Emulsion-acrylic pressure sensitive adhesives are versatile and provide lower operating temperatures, better UV stability and improved clarity over other formulations. Their applications will withstand moisture and temperature changes to deliver no matter the application.
