A solvent-based adhesive such as rubber cement is an ideal gluing agent for latex. Rubber cement is much better to use than latex milk or liquid latex. Latex milk does not curl as much as rubber cement, but it does not hold as tight. It also tends to have uneven texture and become bubbly. Rubber cement, on the other hand, makes latex curl up, but it dries fast. When rubber cement dries, the latex uncurls on its own. Another benefit of rubber cement is it dries clear. Your work will look nice and neat sans traces of glue. Latex is a challenging fabric to wear, so the adhesive joining the seams must be strong enough not to snap any moment. You can use these adhesives recommended by latex garment makers to secure your seams. Solvent-based Rubber Cement Rubber cement is made from a solution of natural latex and an organic solvent which is usually heptane. The latex seams adhere to each other through contact welding. The solvent in the rubber cement has an important role in making the latex pieces fuse when they come into contact after applying the adhesive. The rubber cement adhesive is more effective when you allow it to sit for 12 to 24 hours after fusing the latex pieces. Most brands of rubber cement need to be mixed with solvent at a certain ratio, usually one part rubber cement to 1 part solvent (heptane). Apply rubber cement to the seams that need to fuse and let the solvent evaporate. This step will take around 5 to 10 minutes. Then, press the joined pieces firmly together using a roller. Let it sit for a while for the rubber cement to reach its optimal strength. Elmer’s, Best-Test and other solvent-based contact cement for latex are available on Amazon. Rubber Cement Water-based The water-based rubber cement practically works like the solvent-based one. It also uses the principle of contact welding but uses water instead of the solvent. Ammonia is added to the solution as a dispersing agent to keep it from clumping. Similar to the solvent-based rubber cement, the water-based glue also needs to be thinned for proper application. But this time, water is used. It also follows the same procedure in applying the adhesive to your latex seams. Check out Copydex and other water-based rubber cement adhesive on this Amazon link. It is important that you use the right glue in joining latex fabrics. Latex glue works only based on physical glue reaction. Adhesion of the latex pieces works differently from chemical adhesives where the bonding takes place due to chemical reaction, the process used with two-component glue. When you apply glue to natural latex with 0.25 to 0.6 mm thicknesses, you will notice the curling of the latex fabric. The solvent in the latex glue increases the surface area of the latex, making it expand, displayed by the curling. Thicker latex fabrics will not show curling because they are thick enough not to deform. The best thing about latex glue is that it is transparent and flexible and remains flexible after curing, which is a good quality for an adhesive when making latex clothing.
