Description Hysol 143 is a modified, two-component, impact resistant epoxy adhesive formulated for a good balance of properties. Its medium viscosity and 1:1 ratio makes Hysol 143 easy to apply. The neutral color of this adhesive provides almost invisible bond lines. Recommend Substrates: metals, plastics and wood. Features Excellent tensile lap shearImpact resistant Room temperature or heat cure1:1 mix ratio Neutral Color Typical Properties Part A Part B Mixed Color Milky-white Amber Cream Viscosity, Poise 3000-4500 145-175 - Specific Gravity @ 77°F 1.7 1.06 1.10 Handling Mixing: This product requires mixing two components together just prior to the application. Complete mixing is necessary. The temperature of the separate components prior to mixing is not critical, but they should be at room temperature. Part A Part B Mixed By weight 100 85 - By volume 1 1 - Pot life @ 77°F, 100 grams 20 – 25 minutes Application Mixing – Bulk: Combine Part A (resin) and Part B (hardener) in the correct ratio and mix thoroughly until the color and consistency are uniform. Ratios given above can be used for measuring larger amounts. Mixing the adhesive just prior to use is recommended. Heat build-up during or after mixing is normal. Do not mix quantities greater than two pounds as dangerous heat build-up can occur causing uncontrolled decomposition of the mixed adhesive. Mixing smaller quantities will minimize the heat build-up. Mixing – Cartridges: Place cartridge in proper dispenser. To begin using a new cartridge, remove cartridge cap and dispense a small amount of adhesive, making sure Part A and Part B are extruding. Attach nozzle and dispense approximately 1-2" before applying onto the part being bonded. Partially used cartridges can be stored with mixing nozzle attached. To reuse, remove and discard the old nozzle, attach new nozzle and begin dispensing. Application: Bonding surfaces should be clean and dry. For optimum surface preparation, consult Dexter's bulletin "Preparing the Surface for Adhesive Bonding". Once the adhesive is applied, the bonded parts should be held in contact until the part has developed handling strength. It is not necessary to clamp the parts unless movement during cure is likely. Cure: Hysol 143 may be cured for 3 days at 77°F to achieve normal performance. Accelerated cures up to 200°F (for small masses only) may be used as an alternative. For example 1 hour at 180°F will give complete cure. Clean up: It is important to remove excess adhesive from the work area and application equipment before it hardens. Many common solvents and citrus cleaners are suitable for removing uncured adhesive. Consult with your supplier's information pertaining to the safe and proper use of solvents.
