Product Description
STWD169 is a two component room temperature curing epoxy adhesives; it is particularly recommended as bonding agents for dry-fixing curtain wall, bonding agent for external reinforcement (steel plate stiffeners to concrete/steel structural members), anchoring grout for reinforcing steel and prestressing cables in concrete and rock, and repairing material for concrete cracks. It has high density, high strength, low viscosity and good liquidity. Which is insensitive to temperature and humidity during application, reinforcement impact and strong with high adhesive strength to metal and concrete substrate. It has stable anticorrosion properties against many chemical media, good impact resistance, wearable, acid, alkali and salt spray resistance. It is anti-aging, seawater immersion resistance. It can be applied inside water and curing under water.
