10 lt

  (net weight: 0.66 kg) Chemically composed of glass, their hollow form helps reduce matrix density. Their spherical shape prevents stress concentration and, as a consequence, increases cracking resistance of putties. In comparison to microballoons, they are physically harder, more waterproof and somewhat more difficult to sand. They have a fractional survival rate of 80% or more, for continuous use at 250 psi in highly filled resin systems. As a result, glass bubbles are also used as an additive for a number of buoyancy applications, in depths of up to 600 m in seawater. Suggested quantity to add in putties depends upon application.   Technical characteristics Isostatic crush strength (psi): 250 True density (g/l): 100 to 140 (typical 125) Bulk density: 60% of true density Thermal conductivity at 21 oC (Wxm-1xK-1): 0.047 Alkalinity (mEq/g): ≤ 0.5 Mean particle size (μ): 65   Conversion data 1 l = 1.057 qt = 33.814 fl oz   Intrastat Number for this product: 70182000..

microballoons, phenolic resin spheres, brown putty for wood filling, microballoons for epoxy resin (net weight: 1.20 kg) Hollow phenolic resin spheres have a distinctive reddish/brown color. This makes them particularly useful for cosmetic joints in wood construction. Although not as waterproof as glass bubbles, microballoons have excellent sanding characteristics. Suggested quantity to add in putties depends upon application. Not compatible with polyester and vinylester resins. Store in tightly closed containers.   Technical characteristics Average hydrostatic compressive strength (psi): 300 Liquid density (g/l): 0.21 to 0.25 Average bulk density (g/l): 104 Mean particle size (μ): 65 to 90 Moisture content (% by weight): 5   Conversion data 1 l = 1.057 qt = 33.814 fl oz   Intrastat Number for this product: 39094000..

microfibers, wood cellulose fibers, putty for wood bonding, microfibers for epoxy resin (net weight: 2.50 kg) Very fine wood cellulose fibers, used to reinforce the matrix and create structural adhesives for various applications. Microfibers absorb and hold great amounts of resin. Very hard wearing, hard to sand, very good for bonding wood. Where a strong bond is required microfibers should be preferred. Suggested quantity to add in putties depends upon application.   Technical characteristics Loose density (g/l): > 40 Moisture content (%): < 7.5 Average Fiber Length (μ): 155 Average Fiber Thickness (μ): 1 to 2 Average Fiber Width (μ): 20   Conversion data 1 l = 1.057 qt = 33.814 fl oz   Intrastat Number for this product: 68062090..
