Wikify date July 2011 Porcelain and ceramic fixtures are being more commonly glazed with 2 part epoxy compounds. The first component is a clear or opaque resin combined with a catalyst or hardener. The proper procedure requires that the non porous fixture be sand blasted to create a rough surface for the epoxy primer to adhere to. Once the primer has dried the topcoat is applied. Since a true epoxy begins to yellow at the age of 1 year acrylic urethane compound is used in the topcoat. This resin is also catalyzed with a hardener and can last up to 15 years or more with proper maintenance. Formica countertops can also be glazed in this fashion using a faux stone or granite look.

Epoxy putty is a room temperature hardening substance used as a space filling adhesive. It is stored until use as two components of clay like consistency. Kneading the two components into each other creates an exothermic chemical reaction that activates the substance for use by catalyzing an epoxy epoxide polymerisation reaction.

BT Epoxy belongs to the group of thermoset resin s used in printed circuit board s PCBs . It is a mixture of epoxy resin , a common raw material for PCBs and BT resins. BT stands for Bismaleimide Triazine resin. This is in turn a mixture of Bismaleimide , which as such is also used as a raw material for PCBs and Cyanate Ester . Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name. In presence of a bismaleimide the double bond of the maleimide group can copolymerize with the cyano groups to heterocyclic 6 membered aromatic ring structures with two nitrogen atoms pyrimidines . The cure reaction occurs at temperatures up to 250 degrees C, and is catalyzed by strongly basic molecules like Dabco diazabicyclooctane and 4 DMAP 4 dimethylaminopyridin . Products with very high glass transition temperatures Tg up to 300 degrees C and very low dielectric constant can be obtained. These properties make these materials very attractive for use in PCBs.

Epoxy granite is used instead of cast iron and steel for better vibration damping , longer tool life, and lower assembly cost. Machine tool base Machine tools and other high precision machines rely upon high stiffness, long term stability, and excellent damping characteristics of the base material for their static and dynamic performance. The most widely used materials for these structures are cast iron, welded steel fabrications, and natural granite. Due to the lack of long term stability and very poor damping properties, steel fabricated structures are seldom used where high precision is required. Good quality cast iron that is stress relieved and annealed will give the structure dimensional stability, and can be cast into complex shapes, but needs an expensive machining process to form precision surfaces after casting. Good quality natural granite is becoming more and more difficult to find, but has a higher damping capacity than cast iron. Again, as with cast iron, the machining of natural granite is labour intensive and expensive. Process Image Aggregate.jpg thumb Epoxy granite aggregate Precision granite castings are produced by mixing granite aggregates which are crushed, washed, and dried with an epoxy resin system at ambient temperature i.e., cold curing process .

Vinyl Ester , or Vinylester , is a resin produced by the esterification of an epoxy resin with an unsaturated carboxylic acid monocarboxylic acid . The reaction product is then dissolved in a reactive solvent, such as styrene, to a 35 45 percent content by weight. It can be used as an alternative to polyester and epoxy materials in matrix or Composite material composite materials , where its characteristics, strengths, and bulk cost intermediate between polyester and epoxy. Vinyl ester has lower resin viscosity approx 200 cps than polyester approx 500cps and epoxy approx 900cps . In homebuilt airplanes, the Glasair and Glastar kit planes made extensive use of vinylester reinforced fiberglass structures. It is a common resin in the marine industry due to its increased corrosion resistance and ability to withstand water absorption.

B staging is a process that utilizes heat or UV light to remove the majority of solvent from an adhesive , thereby allowing construction to be staged. In between adhesive application, assembly and curing, the product can be held for a period of time, without sacrificing performance. Attempts to use traditional epoxy epoxies in IC packaging often created expensive production bottlenecks, because, as soon as the epoxy adhesive was applied, the components had to be assembled and cured immediately. B staging eliminates these bottlenecks by allowing the IC manufacturing to proceed efficiently, with each step performed on larger batches of product.

unreferenced article date July 2008 Mortite putty is a type of putty that consists of titanium dioxide as its main ingredient. The putty has a specific gravity of 1.34, and has the characteristics of being pliable, off white and giving off very little odor. The material stays soft and pliable for an extended period of time. Mortite putty can be used as caulking around conventional windows installed in conventional wooden or metal frames see glazing . It is also used as a form for epoxy work, since epoxy does not adhere to this material. Mortite putty has also been applied to the metallic structure supporting the magnet for a dynamic speaker to cut unwanted resonance of the metal structure, leading to improved speaker performance. It has also been used as a sonic damping material in sensitive phonograph components. chemistry stub Category Plastics ... more details

Image Rifle Bedding.JPG thumb Bedding epoxy in a stock howto date November 2011 Rifle bedding also known as glass bedding is the process of filling gaps between the action and the stock of a rifle with an epoxy based material. The bedding creates a stable and precise fit for the contact surfaces. Bedding is a technique employed in accurizing a rifle and to a lesser extent prolonging the life of the stock. Purpose Increased Accuracy Bedding increases accuracy in part by relieving stress on the action. The rifle s action will rarely sit flush in the stock without bedding. This causes the action to flex when tightening the bolts holding the action to the stock. The flexing results in a loss of accuracy. Bedding will create a flush surface for the action and prevent flexing. Bedding also reduces movement of the action in the stock. Without bedding, the action may be more likely to shift after a shot. If the action shifts and does not return to same spot in the stock the rifle will lose the ability to maintain zero. Prolonged Stock Life Bedding can help prolong the life of the stock. Repeated recoil forces can cause movement of the action in the stock. As the action moves, friction can create wear in the stock surface. Eventually the repeated wear can ruin the stock. Methods of Bedding Several different methods of bedding can be used depending on the type of stock, desired results and level of experience of the person attempting to perform the bedding. Methods include Full contact bedding of the action with the barrel floated. Full contact bedding of the action and the barrel. Full ... a slow, hard drying epoxy is used as bedding for a rifle.
