BONDiT™ B-481

B-481 handles harsh environments easily and is particularly effective against moisture, salt water, acids, alkalies, oils, fuels and detergents, and is suitable for autoclave applications. B-481 has high thermal stability, readily handling 350°F continuous. B-481 offers good corrosion resistance. The intrinsic flexible resin
properties of B-481 permit assembly of materials with dissimilar thermal expansion and survive thermal cycling down to -65°F. Yet it offers high tensile strength with the flexibility. Likewise, mechanical vibration, shock and impact are absorbed while protecting surfaces, bonded assemblies and encapsulated sensitive electronics. The B-481 system is often superior in performance to urethane adhesives, sealants and coatings. B-481 may be pigment or dyed for color, or be made conductive.
B-481 is unfilled and low viscosity, while B-481TH is silicate filled and thixotropic, meaning a thick coating on vertical surfaces will not sag, but is easily poured from a can. Apply B-481 by roller, brush or spray. B-481 is very easy to use with low HAZMAT impact as a 100% solids epoxy system--no plasticizers that bloom to the surface and no solvents causing VOC problems. B-481 as the unfilledversion is most useful for potting and clear coating applications to replace urethanes while the filled version B-481 TH is most useful as an adhesive

A wide range of curing regimes may be employed: ambient set in 6 hours, tack free in 12 hours, and 95% cure in 24 hours; cure at 150°F tack free in 2 hours 98% in 6 hours; or 3 hours full cure at 200°F with no ambient incubation time. Mix part A with part B, 2:1 ratio by volume or weight. Degassing is optional. Pot life is typically 40 minutes, at ambient temperature. Surface prep by abrading or grit blasting substrates with #100 AlOx followed by degrease and/or alcohol wipe. Often no abrasion is necessary with tolerance to dirty substrates.

Superior chemical resistance for moisture and oil, acids and bases, fuels and solvents in continuous full submersion. High stability to 350°F continuous as a rugged system. Suitable for autoclave applications.

Two part, primerless, semi-rigid epoxy, high tensile strength, ambient and thermal cure. Available in handheld and pneumatic gun actuated cartridges, quarts, gallons and drums.
