Storage

The usable shelf life of unopened containers of BONDiTTM B-481 resin is one year, and should be stored in cool, dry place. When not in use, containers should be kept tightly closed. BONDiTTM B-481 is available in side-by-side handheld and pneumatic actuated gun cartridges, quarts, gallons, pails and drums, as well as custom packaging, such as premixed and degassed frozen cartridges. B-481 is offered as paste for caulking, and electrically and thermally conductive with or without metal filler. A very high wear ceramic version is also available

Easy to Use

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.

Curing Guide

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.

Product Info

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
