Overview of 3-Glycidyloxypropyltrimethoxysilane
3-Glycidyloxypropyltrimethoxysilane, also called GLYMO or GPTMS, is a versatile organosilane used in plastics and rubber to help organic polymers stick to surfaces like glass fibers, metals, and fillers. The chemical formula for it is C9H20O5Si (CAS 2530-83-8). The epoxy group reacts with resins, while the trimethoxysilane groups bond to surfaces after hydrolysis. This additive improves strength, water resistance, and durability in composites, coatings, and sealants for the plastic and rubber industries.
Applications of 3-Glycidyloxypropyltrimethoxysilane
Coatings, Paints & Adhesives
3-Glycidyloxypropyltrimethoxysilane helps coatings like epoxy, polyurethane, and acrylic stick better to glass, metal, and mineral surfaces. It also increases the resistance to corrosion and water. When used in sealants and adhesives it improves wet strength and, in many cases, eliminates the requirement for primers, thus making it suitable for polysulfide and urethane system that are used in rubber and plastics.
Plastics, Rubber & Composites
It is used to treat glass fibers and fillers in reinforced plastics, rubber, and composites. This treatment improves strength, durability, and the even spread of fillers. It is often found in FRP, engineering plastics, and rubber products for the automotive and construction industries.
Other Industrial Uses
In inks, foundry resins, and electronics encapsulation, 3-Glycidyloxypropyltrimethoxysilane modifies surfaces for better compatibility and electrical properties. Pair it with products like Zinc Stearate for rubber processing or Cobalt Octoate for resin curing, and explore more at the homepage.
Safety & Handling Guidelines
- Store in a cool, dry, and well-ventilated place below 30°C. Keep containers tightly closed.
- Wear protective gloves, goggles, and clothing; avoid skin, eye contact, inhalation, and moisture as it is moisture-sensitive and causes serious eye damage.
- Keep away from heat, sparks, and incompatibles; dispose per local regulations and review MSDS for full details.
