In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
The characteristics of polycarbonate compare to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is stronger and will hold up longer to extreme temperature. Thermally processed material is usually totally amorphous, [ 7 ] and as a result is highly transparent to visible light , with better light transmission than many kinds ...
Rabbit-skin glue, in pellet form (left) and partially dissolved in water (right) Rabbit-skin glue is a type of animal glue used as a sizing and an adhesive, it is essentially refined rabbit collagen. The glue has been used for centuries for stretching and priming canvases for oil painting. It has also been an ingredient in traditional gesso.
Advantages of polyurethane glue in the bookbinding industry: PUR is better than hotmelt or cold glue for most applications. Because of the lack of moisture in the glue, paper with contrary grain direction can be glued without problems. Even printed and supercalendered paper can be bound without problems. It is the most economical glue, with a ...
Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.
Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent. [5] Solvent bonding can be performed using a liquid or gaseous solvent.
This so-called phase separation between both blocks can be more or less important, depending on the polarity and the molecular weight of the flexible chain, the production conditions, etc. The crystalline or pseudo crystalline areas act as physical cross-links , which account for the high elasticity level of TPU, whereas the flexible chains ...
Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
