B-482 handles harsh environments easily and is particularly effective against moisture, salt water, acids, alkalies, oils, and detergents. B-482 has high thermal
stability, readily handling 350°F continuous. B-482 offers good corrosion resistance. The intrinsic flexible resin properties of B-482 permit assembly of materials with dissimilar thermal expansion and survive thermal cycling. Yet it offers high tensile strength with the flexibility. Likewise mechanical vibration, shock and impact are easily absorbed by B-482 and while protecting surfaces, bonded assemblies and encapsulated sensitive electronics. The B-482 system is often superior in performance to urethane adhesives, sealants and coatings.
B-482 is unfilled and low viscosity, while B-482TH is silicate filled and thixotropic, meaning a thick coating on vertical surfaces will not sag, but is easily poured from a can. Apply B-482 by roller or brush. B-482 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-482 as the unfilled version is most useful for potting and clear coating applications to replace urethanes while the filled version B-482TH is most useful as an adhesive

- 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 4 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.
- Applications Notes
When interpreting adhesion test data care must be taken. The data is highly dependent on a number of factors, particularly curing regime and geometry of the bond joint. The test data differences between ambient cure and post cure demonstrate significant variation in adhesive tensile strength. Increased tensile strength tends to produce higher bond strength. Higher temperature cure also produces higher adhesion to the substrate, a consequence of chemical reactions being more active at higher temperatures. Time of cure also is an important factor. The adhesive bulk will continue curing forthirty days, becoming stronger. But also, the adhesive links to the substrate continue to develop in number and cross-link density...thus continuing to increase the bond strength over a long period...even months as the adhesive may actually slowly migrate into the substrate. So, an ambient cure will continue to develop until, for example, reaching something in the neighborhood of 75% of ultimate bond strength by high temperature curing. Geometry of the bond joint is critical for maximizing the joint strength, as seen in comparing the difference in lapshear data of UHMW/UHMW with that of UHMW/ Steel. Both tests are identical, except the steel substrate is rigid. Under increasing load the more flexible UHMW/UHMW joint rotates out of 180° shear angle, and peel forces take affect...thus lowering the break strength of the joint. The stiff UHMW/Steel joint stays nearly 180° parallel to the direction of force and thereby maintains almost true shear angle. That results in much higher test values.The caution is the test data is comparative, rather than absolute for any particular application.
