Hapflex™ 780

About
HAPFLEX 700 & 800 products are a series of low hazard, colorless, high strength, elastomers available in Shore hardnesses from 65A to 72D. HAPFLEX 700 & 800 products exhibit high tensile strength, high tear strength, and excellent elongation. All HAPFLEX 700 & 800 products cure at room temperature and can be accelerated with heat. Another key attribute of the 700 & 800 SERIES is that the base color of all components is colorless. For user convenience, HAPCO has designed this series in 2 speeds so the user can “customize” production rates and cure times. The fast and regular versions can be blended to user customize the gel time and cure time. HAPFLEX 700 & 800 SERIES can be used for mechanical, electrical, and mechanical/electrical applications. In addition, HAPFLEX 700 & 800 products show superior water immersion properties and superior adhesion when used in combination with Hapco’s one part PRIMER 200.&&
