On Jan. 27, the Environmental Defense Fund, along with several other organizations, submitted a petition to the Food and Drug Administration that urged the agency to limit the use of the chemical bisphenol-A (BPA) in food packaging. BPA is just one of many chemicals used in plastics that a...
Flexible Epoxy Resin GluesEpoxy glues and adhesives aren't recognized for being particularly flexible. Long-chain aliphatic epoxy resins, on the other hand, allow epoxy adhesives to be made more flexible. Nonetheless, the use of this flexible epoxy resin reduces the glue's hardness. As a result...
Glues and adhesives for wood and plastic So, what tools will you need? In the coming article, you'll learn about tools that measure, cut, drill, nail, tighten and loosen, hold, clamp, test, paint, and more. Most important, you'll see which ones you really need and how to use them...
A:For hot glues or other commercial adhesives stuck to fabrics, ice can be used to freeze the stained area. Place ice cubes in a bag and set them over the stain to harden and freeze the glue. Once frozen, the glue should be easier to separate from the fabric using a dull edged tool...
Before attempting to glue metal to plastic, it's important to know what types of adhesives can accomplish the task. Not all adhesives are alike — wood glue and school glue, for instance, are designed for porous materials and would not work well on either metal or plastic. Certain glues th...
This is the most durable kind of plywood types available and makes use of hardwoods like spruce, mahogany, and birch plus adhesives to create strong boards that are moisture and heat resistant. The design of aircraft plywood incorporates very thin veneers that make it flexible and light while ma...
The technology of animal and fish glues advanced during the 18th century, and in the 19th century rubber- and nitrocellulose-based cements were introduced. Decisive advances in adhesives technology, however, awaited the 20th century, during which time natural adhesives were improved and many ...
and beeswax were used as sealants (protective coatings) and adhesives in ancient andmedievaltimes. Thegold leafofilluminatedmanuscripts was bonded to paper by egg white, and wooden objects were bonded with glues from fish, horn, and cheese. Thetechnologyof animal and fish glues advanced during the...
fastening challenges. These tapes come in a wide variety of backings, each suitable for specific end-uses. This is exactly why adhesive tape use is on the rise in high-performance building and construction. If you’re still using glues, sealants or even nails, consider pressure-sensitive tape...
Specimens bound with ductile adhesive (PUR) showed a slightly higher number of cycles to failure (Nf) at low-stress levels and lower Nf at high-stress levels in comparison to more brittle adhesives (MUF, fish glue). In general, the performances of animal glues and MUF were similar in both...
