a Resin Descriptions Chlorendic Polyester Resins Chlorendic polyester resins are based on the incorporation of chlorendic anhydride or chlorendic acid (also called HET acid) into the polymer backbone. Their most notable advantage is superior resistance to mixed acid and oxidizing environments, which makes them widely used for bleaching and chromic acid or nitric acid containing environments, such as in electroplating applications. The cross linked structure is quite dense, which results in high heat distortion and good elevated temperature properties. This is a dense structure that can display reduced ductility and reduced tensile elongation. Despite good acid resistance, chlorendic resins should not be used in alkaline environments. Due to the halogen content, chlorendic resins display flame retardant and smoke reduction properties. The DION® 797 series are chlorendic anhydride based resins with good corrosion resistance and thermal properties up to 350° F. DICING 797 is supplied as a pre -promoted and thixotropic version. An ASTM E-84 flame spread rating of 30 (Class II) is obtained with the use of 5% antimony trioxide. Many thermal and cor- rosion resistant properties are superior to those of competitive chlorendic resins. Castings APR 2 6 2016 Atprime® 2 Bonding & Primer Atprime® 2 is a two -component, moisture -activated primer that provides enhanced bonding of composite materials to a variety of substrates, such as FRP, concrete, steel, or thermoplastics. It is especially well suited for bonding to non -air -inhibited surfaces associated with contact molding or aged FRP composites. This ability is achieved due to the formation of a chemical bond to the FRP surface. Atprime® 2 is free of methylene chloride and features good storage stability. Atprime® 2 is well-suited for repairs of FRP structures. Many FRP structures have been known to fail due to the failure of secondary bonds, which can serve as the weakest link in an otherwise sound structure. Thus Atprime® 2 merits important consideration in FRP fabrication. The curing mechanism relies on ambient humidity and does not employ peroxide chemistry.
