  • Superior dimensional stability
  • High degree of flexibility
  • Excellent thermal shock resistance
  • Fluorosilicones offer chemical resistance capability
Urethane modified epoxies
  • Very good dimensional stability
  • High elongation
  • Low modulus
Polysulfide modified epoxies
  • Excellent toughness

  • Good dimensional stability

Low/medium/high viscosity liquid elastomeric systems including pastes provide safe, reliable protection against dust, dirt, fluids, gases, contaminants. These high elongation compounds exhibit good weathering characteristics, aging properties and offer resistance to cracking, blistering, and embrittlement under harsh conditions. Most noteworthy is their ability to withstand vibration, shock, impact, heating/cooling cycles, humidity. Select durable, flexible compounds have proven effective in sealing dissimilar substrates and joints subjected to high/moderate cyclic movement even at low temperatures. Additionally systems have been developed for damp conditions, chemical attack, abrasion and wear. Multipurpose sealants offer fast fixture speeds, low shrinkage, gap filling, good electrical insulation for interior/exterior use. They have proven successful in guarding key components against high pressure.
