Pioneer Epoxy Adhesives entered the PBA 3x3 in 2021, fielding the Pioneer Pro Tibay as a guest team. [1] They were forced to forfeit two games in the opening day of the first leg of the inaugural 2021 PBA 3x3 season due to inability to secure a medical clearance from the Games and Amusements Board.
The first batches of Araldite epoxy resins, for which the brand is best known, were made in Duxford, England in 1950. [1] Araldite adhesive sets by the interaction of an epoxy resin with a hardener. Mixing an epoxy resin and hardener together starts a chemical reaction that produces heat – an exothermic reaction. [2]
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline. Simple epoxides are often referred to as oxides. Thus, the epoxide of ethylene (C 2 H 4) is ethylene oxide (C 2 H 4 O). Many compounds have trivial names; for instance, ethylene oxide is called "oxirane".
The left component is Epoxy Base Resin and the right one is Epoxy Hardener. Both are to be mixed thoroughly in equal quantity to get epoxy putty. Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application.
Use of epoxy requires careful attention to the mixing ratio of the two parts. It bonds to most cured wood glues (except PVA). [ 25 ] Two-part epoxy adhesive is very resistant to salt water, most epoxy is heat resistant up to 177 °C (351 °F), the formulations containing powdered metal and rubber or plasticizers are very tough and shock resistant.
The Pioneer plaques are a pair of gold-anodized aluminum plaques that were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by intelligent extraterrestrial life. The plaques show the nude figures of a human male and female along with several symbols ...
The purpose of the cush is for dampening of chatter, absorption of impact landings, airs, grip, and overall added protection for a light epoxy board. Jim Richardson, 25-year veteran shaper on the North Shore of Oahu, first pioneered this technology in the mid 1990s.
