- Product Info
B-45 handles harsh environments easily and is particularly effective against moisture, salt water, acids, alkalies, oils, gasoline and detergents. B-45 has high thermal stability, with a continuous operational rating of -50°F to +350°F. B-45 offers good corrosion resistance. The flexible properties of B-45 permit assembly of materials with dissimilar thermal expansion and will survive thermal cycling. Likewise mechanical vibration, shock and impact are easily absorbed by B-45 and it protects surfaces, bonded assemblies and encapsulated sensitive electronics is superior in performance to urethane adhesives, sealants and coatings. B-45 is useful as a direct replacement for urethane elastomers with the superior benefits that it requires no primer for adhesion and offers high chemical resistance. B-45 is also available as a paste or caulking compound and electrically or thermally conductive compounds. Apply B-45 by roller or brush. B-45 is very easy to use with low HAZMAT impact with no plasticizers that bloom to the surface and no solvents causing VOC problems. The product is also available in the thixotropic version B-45TH, providing a thick coating on vertical surfaces which will not sag, and yet is easily poured from a can.
Applications & Uses

- Curing Guide
A wide range of curing regimes may be employed: ambient set in 4 hours, tack free in 12 hours, and 97% cure in 24 hours. Post curing at 150°F, after 2 hours at ambient to allow bubble escape, will cure 98% in 4 hours; or 3 hours at 200°F for 100% cure. Mix part A with part B, 2:1 ratio by volume or weight. Degassing is optional. Pot life is typically 30 - 40 minutes, at ambient temperature. Surface prep by abrading or grit blasting substrates with #100 AlOx followed by degrease and/or alcohol wipe for optimum adhesion.
- High Chemical Resistance
Superior chemical resistance for moisture, gasoline, oil, acids and bases in continuous full submersion. High thermal stability in a rugged flexible system. Excellent for exterior and interior applications
- Easy Use
Two part, primerless, flexible epoxy, ambient and thermal cure. Low HAZMAT impact. Available in handheld and pneumatic gun actuated cartridges, quarts, gallons and drums
