BD3131 is a 10:1 two-part structural adhesive designed to substitute or complement welding, riveting, clinching and other mechanical fastening techniques used in the manufacture of transportation vehicles and assembly components. BD3131 is suitable for bonding sidewall panels, floors and parts made of aluminum, stainless steel, galvanized steel, fiberglass reinforced polymers, acrylic panels, gel coated panels, and many other plastics. This product is suitable for use by experienced professionals only. Test with actual substrates and conditions must be performed to ensure proper adhesion and material compatibility.
Cure Mechanism : Two-component mix, based upon free radical polymerization.- Method of Application
- Substrate Preparation : Surfaces should be clean and dry. Remove heavy oils an dirt with suitable solvent that will not harm the substrate. A 2 to 1 solution of isopropyl alcohol to water solution is recommended, bust substrate compatibility must first be tested. Heavily contaminated areas must be more rigorously cleaned before bonding.
- Mixing from Cartridges : We recommend a high-quality pneumatic dispenser should be used. Avoid manual dispensers as they can create non-uniform dispensing due to the pulsing nature of the operator. The preferred dispenser is a Sulzer MixPac DP400/10 with a dispensing cradle. The recommended static mixers are the Sulzer MixPac MFX 10-18; MFX 10-24, MFQX 10-24, or the MGQ 10-19 for high flow applications.
Insert the cartridge into the proper dispenser, and unscrew the camlock nut from the nose of the dispenser. Attach the airline to the dispenser, and adjust the air pressure to the lowest possible pressure using the air regulator on the dispenser. Dispense a small amount of product into a paper cup, until you see both the A-side and the B-side protrude from the nose of the cartridge into the paper cup. Only a few CC’s of the product should be dispensed to balance the pistons. Insert the manufacturer recommended static mix tip and secure the tip with the camlock nut. Slowly increase the air pressure, and dispense about the length of the static mix tip into the paper cup. Mix the contents of the cup with a wooden mix8 stick and toss away into the trash. Now begin the application. using the dispenser tool air pressure to achieve the desired flow rate. If application stops for a period of time exceeding ½ of the gel time, the static mix tip must be removed and a new one installed using the steps outlined as above.
Note : Cooler temperatures will afford a longer working time, whereas warmer temperatures will afford a shorter working time. It is best for storage of partially used cartridges to retract the air pressure on the dispensing tool, remove the cartridge from the dispensing tool, remove the static mix tip. And replace the static mix tip with the nose plug that was on the cartridge. Store in an upright location. - From Meter Mix/Bulk Dispensing Units : For advice on setting up meter mix equipment, please see manufacturer’s recommended products and set up procedures. Any questions can be directed toward our Technical Services Department.
- Important Note : Large quantities of BD3131 will generate significant heat during the curing process. Therefore, limit the bond-line thickness to approximately .125 inches. Large masses, greater than 50 grams may boil or blister, therefore purge volumes should be limited to amounts less than 50 grams. Exposure of materials, cartridges greater than 95°F (35°C) will rapidly decrease shelf life.
- Removal : Excess material can be best removed before curing with a dry wipe. Uncured material may be removed from tools and equipment with an eco-friendly product, such as a citrus cleaner. Strictly follow the solvent manufacturer’s warnings and instructions for use. Also, if surfaces that were cleaned are to be re-bonded, they must be thoroughly wiped with a 2 to 1 isopropyl alcohol and water solution. Adhesion testing is always recommended in these cases. Cured material can only be removed mechanically. A solvent wipe should follow mechanical removal if re-bonding is to be done.
- Overpainting : If over painting is desired, the paint and the paint process compatibility must be tested before use. BD3131 should not be exposed to paint baking temperatures until it has achieved its full cure. It should be understood that the hardness and film thickness of the paint may impair the elasticity of the adhesive and lead to cracking of the paint film over time.
- Limitations : BD3131 will not bond polyolefins or other low energy surfaces, including such products as polyethylene and polypropylene, Teflon, polytetrafluoro-ethylene, fluorine containing polymers, polyacetals, or nylon. Adhesion to, and compatibility with composites with these materials should be tested before using. Cure may be accelerated with heat, but avoid temperatures over 110°F (43°C). Product will cure at temperatures well below 40°F (4°C), but will do so very slowly.

- Storage and Shelf Life
- Storage : Keep stored in original containers between 50°F (10°C) and 75°F (24°C) and avoid exposure to direct sunlight. Prolonged exposure of product to temperatures above 90°F (32°C) should be avoided. Exposure to temperatures above 95°F (35°C) will rapidly decrease shelf life. Naturally, the cooler the product is stored in, the longer the shelf life. Refrigeration of components will extend the shelf life. Products should not be frozen!! No formal recommendations can be made since storage conditions at customer locations may fluctuate and are beyond the manufacturer’s control. Before any product is used, customers must acclimate the product to normal room temperature (75°F/24°C) for several days before use for optimal properties.
- Shelf Life : 12 months (Drums, Pails, Cartridges). Stored at or below 75°F (24°C) and no direct sunlight.
