3Mâ„¢ Glass Bubbles D32/4500 is engineered hollow glass microspheres that are alternatives to conventional fillers and additives such as silicas, calcium carbonate, tale, clay, etc., for many demanding applications. These low-density particles are used in a wide range of industries to reduce part weight, lower costs and enhance product properties. The spherical shape of 3M glass bubbles offers a number of important benefits, including: higher filler loading, lower viscosity/improved flow, and reduced shrinkage and warpage. It also helps the 3M glass bubbles blend readily into compounds, and makes them adaptable to a variety of production processes, including spraying, casting and molding. In addition, they offer greater survivability under demanding processing conditions, such as injection molding, and also produce stable voids, which results in low thermal conductivity and a low dielectric constant. The chemically stable soda-lime-borosilicate glass composition of 3M glass bubbles provides excellent water resistance, to create more stable emulsions. They are also non-combustible and non-porous, so they do not absorb resin. And, their low alkalinity gives 3M glass bubbles compatibility with most resins, stable viscosity and long shelf life. 3Mâ„¢ Glass Bubbles D32/4500 offer the same combination of strength and light weight as standard 3M glass bubbles, with an added surface treatment of special coupling agents, for use in high- tech applications such as aerospace and hydrospace syntactic foam, radomes and printed wire boards. They are available in a variety of sizes and grades for various product and processing requirements.

D.E.N.® 425 is a liquid reaction product of epichlorohydrin and phenol-formaldehyde novolac. D.E.N.® 425 Epoxy Novolac Resin is an epoxidized phenolic resin of higher functionality than standard bisphenol Abased liquid epoxy resins. Epoxy novolac resins combine, in one molecule, the thermal stability of a phenolic backbone with the reactivity and versatility of an epoxy. They are distinguished by particular good thermal stability, mechanical strength and resistance against chemicals. They find ready acceptance for lining pipelines, storage tanks and pumps. D.E.N.® 425 Epoxy Novolac Resin has been developed to fill the gap between the two functional standard bisphenol F based liquid epoxy resins and the high viscous epoxy novolac resins. It has a viscosity similar to a standard bisphenol A based liquid epoxy resin. The multi-functionality, ± 2.5 epoxy groups per mole, of D.E.N.® 425 Epoxy Novolac Resin produces a more tightly cross-linked cured system than bisphenol A based liquid epoxy resins having improved high temperature performance and improved resistance against various chemical.
