Abstract
Adhesives, particularly pressure sensitive adhesives, and adhesive tapes, e.g., harness tapes, that exhibit low-fogging characteristics. The adhesive is a cured composition of an elastomer and a cure system including a sulfur-containing and a zinc-based curing agent.
Claims25
A low-fogging harness tape, comprising:
- a backing, a reinforcing layer, and a pressure-sensitive adhesive,
- said adhesive is a cured composition, comprising:
- an elastomer including predominantly isoprene,
- a cohesion enhancer,
- a tackifier, and
- a cure system comprised of zinc-containing curing agent, thiuram present at about 0.15 phr or more, and thiazole present at about 0.5 phr or more, said thiuram and said thiazole being present in a ratio of about 1:3,
- said elastomer, cohesion enhancer, and tackifier having Fogging Numbers of about 60 or more when measured neat in the amounts present in said composition, and
- said tape having a Fogging Number of about 50 or more following cure of said adhesive.
