ANEROBIC ADHESIVE GRIPS LIKE A VISE IN SECONDS

AN ANEROBIC, TWO-COMPOND ADHESIVE THAT CURES IN TWO OR THREE MINUTES AT ROOM TEMPERATURE HAS BEEN DEVELOPED BY LOCTITE CORPORATION USING THE ADHESIVE, STEEL-TO-STEEL BONDS HAVE A 3,000-PSI TENSILE SHEAR STRENGTH EQUIVALENT TO THAT OF A HEAT-CURED EPOXY ADHESIVE. BECAUSE OF ITS TWO-COMPONENT SYSTEM, THE LOCTITE ADHESIVE DOES NOT REQUIRE PREMIXING. THE ADHESIVE SETS HARD ONLY WHEN DEPRIVED OF AIR. BECAUSE IT IS SLIGHTLY FLEXIBLE, MINUTE BOND 312 HAS BETTER FATIGUE AND IMPACT PROPERTIES THAN OTHER, MORE BRITTLE ADHESIVES. IN PROPERTIES, PERFORMANCE, AND COST IT IS SIMILAR TO EASTMAN CHEMICAL'S 910 ADHESIVE, A CYANOACRYLATE, WHICH BONDS ALMOST ANY NON-POROUS SURFACE AND GIVES BOND STRENGTHS UP TO 5,000 PSI. BOTH OF THESE ADHESIVES ARE RATHER LOW IN VISCOSITY SO THAT COST PER APPLICATION IS USUALLY LOW. NEITHER ADHESIVE IS RECOMMENDED FOR BONDING LARGE AREAS BECAUSE OF THEIR QUICK SETTING TIMES.
