Today’s hot-melt formulators face many challenges, including variations in the availability of raw material supply and the pressure to reduce formulation costs. High-efficiency polymers can help formulators by reducing formulation viscosity or increasing formulation flexibility, which allows for the exchange of resin or oil for polymers.
Acrylic polymers are widely used in pressure-sensitive adhesive (PSA) applications in the form of emulsion, solvent or radiation-cured systems. They combine good UV resistance, transparency, tailored tack, and stiffness due to a large choice of acrylic and methacrylic comonomers.

The Pressure Sensitive Tape Council’s Tape Summit 2013 will be held May 13-17 at the Sheraton New Orleans Hotel in New Orleans, La. Industry professionals will benefit from a variety of focused learning opportunities, including Tape University, TECH 36, and the Exhibitor and Technical Poster events.
I would like to achieve the high performance of a two-component polyurethane coating, but my application process is only able to handle a one-component system. Can any existing formulations help me make this performance leap?
The adhesives and sealants community will gather April 21-23 to share business information, discover the latest innovations, and network with industry leaders.

Technological advancements, industry innovations and regulatory updates: all these features and more will be highlighted at the 2013 Adhesive and Sealant Council (ASC) Spring Conference and Expo in Atlanta, Ga. The adhesives and sealants community will gather at the Hyatt Regency from April 21-23 to share business information, discover the latest innovations, and network with industry leaders.
Today’s elastomeric joint sealants are quite remarkable. For a relatively low cost, they provide much of the protection against air or water intrusion for many types of assemblies. In these applications, a sealant must adhere tenaciously to the substrates and maintain prolonged flexibility while being bombarded by wind, rain, heat, ultraviolet (UV) light, ice, dirt, and so on.
Moisture-cure polyurethane adhesives, or more particularly, moisture-cure polyurethane binders, are used extensively to combine particulate materials into a solid form either by molding or other processes. These particulate materials can be diverse in physical characteristics ranging from sand and small stones to recycled tire crumb, flexible urethane foam scrap, wood, and fiber.
