S-18 All-Purpose Adhesive

Why do so many trust S-18? Probably because it does so much.

  • Bonds leather, glass, metals, crepe rubber, neoprene and more
  • Remains strong and flexible even in weather extremes
  • Resists water, oil, grease and harsh chemicals
  • All 4 oz. through 32 oz. cans come with a brush-cap top

The rule of thumb is that one ounce of adhesive will cover one square foot of both surfaces to be bonded. For more details, click here for our product calculator.

Why do so many trust S-18? Probably because it does so much.

RH Adhesives’ most versatile neoprene adhesive bonds both porous and non-porous surfaces, and it resists sunlight, water, oil, and heat.  S-18 forms a powerful bond that gets even stronger over time.

S-18 is the go-to choice for the glazing of “drop-in” aluminum windows and is used in the repair and manufacture of fiberglass, Formica, vinyl laminates, EVA foam, and vinyl foam. It’s an excellent way of bonding leather to other substances, too.

S-18 is widely used in the manufacture and repair of a variety of materials to themselves and to each other.

Compatible Materials:  Concrete, crepe rubber, EVA foam, fiberglass, Formica, glass, leather, metals, neoprene, some plastics, vinyl foam, vinyl laminates
