You can make a variety of projects with acrylic and other strong plastics — from small sculptures to large fish aquariums. When it comes to attaching these materials, you'll need an adhesive that can bond and connect them. Weld-On 40 is one cement that can do the job. This product, made by IPS Corp., is designed to bond acrylic to polyester, butyrate, PVC and other materials. Using Weld-On 40 is fairly easy and will connect the needed pieces in your project.
Things You'll Need
- Sandpaper, 240- to 400-grit
- Weld-On 40, Component A and Component B
- Wooden mixing stick
- Plastic glue applicator
Prepare the surfaces of the items you plan to bond with the Weld-On 40. These two items should fit cleanly together without being forced. Sand the surface of the materials where they'll be connected, using a 240- to 400-grit sandpaper.
Bring both parts of the adhesive to room temperature. These components are marked Component A and Component B.
Mix the components together to create the adhesive. For every 100 cc or grams of Component A, add 5 cc or grams of Component B. Stir the mixture together using the wooden mixing stick that comes with the kit. This adhesive can now be used for 20 minutes before it begins to cure.
Place the mixture in a plastic glue applicator with an attached hypodermic needle. This will give you greater control as you apply the adhesive. Apply the adhesive in a thin line to the surfaces you wish to attach.
Put the two materials together, applying enough pressure to remove any air bubbles in the Weld-On 40 mixture. When attached, cover the pieces with cellophane to protect the curing process from the air.
Allow the Weld-On 40 to bond. When the adhesive is applied at about 3/4 inches thick, it will take seven or eight minutes to tack and 20 minutes to cure. The connection will become completely hard within 45 to 60 minutes. The joints should be ready for handling in four hours.
