Joint Seal

Ramseal 70 DS

Two-component 100% solids zero VOC casting resin — 70 Shore D

Overview

Ramseal 70 DS is a 100% solids, zero VOC, two-component, 70 Shore D hardness casting polymer designed to produce dimensionally stable, high-impact, and durable fills. It provides excellent impact resistance, working time, abrasion resistance, and strength. Highly chemical resistant and insensitive to water, it remains thermally stable from -20°F to 150°F (-29°C to 65°C). Ramseal 70 DS is designed for horizontal pour application or use in molds, joints, or voids.

Key Features

70 Shore D Hardness

High Shore D 70 ±5 hardness (ASTM D2240) delivers exceptional rigidity and impact resistance — ideal for structural void fills, spall repairs, and joint fills subject to heavy wheeled traffic and point loads.

High Tensile Strength

5,000 ±500 psi tensile strength (ASTM D412) provides superior structural integrity for concrete repair, casting applications, and load-bearing joint fills in commercial and industrial floors.

Zero VOC / 100% Solids

Fully solids formulation with zero VOC — safe for use in occupied spaces including food-processing plants, cold storage facilities, and interior commercial environments.

Chemical & Abrasion Resistance

Highly chemical resistant and abrasion resistant with low temperature stability down to -20°F — suitable for refrigeration floors, food-processing plants, and chemically aggressive industrial environments.

Typical Applications

  • Concrete spall repair and void filling
  • Expansion joints and crack filling
  • Open molds and castings
  • Commercial and industrial floor repair
  • Food-processing plants and cold storage facilities
  • Walkways, balconies, and horizontal pour applications
