1. 3-Glycidoxypropyltrimethoxysilane (CAS NO.2530-83-8) is a kind of coupling agent with epoxy group.
It can be used as caulking glue or sealant of polysulfide and polyurethane and as adhesive of epoxy resin.
2. This product can also be used in thermosetting resin of filling or reinforcement mode, glass fiber
adhesive and thermoplastic resin of inorganic filler or glass reinforcement, etc. It can be used to improve
 the intensity properties of hard composite materials which use glass fiber roving as reinforcement. It keeps
 the intensity at maximum point after humidity period. 3-Glycidoxypropyltrimethoxysilane can enhance the
electrical properties of epoxy resin-based sealants, packaging materials, and printed circuit boards.
It is capable of improving the adhesiveness between fillers or between resin and matrix.
3. This product can enhance electrical properties of composite materials of inorganic filling, including
nylon and polybutylene terephthalate. It is effective to various fillers, matrix, clay, talc, aedelforsite, silica
and quartz, or metals like aluminum, cooper and iron.
4. 3-Glycidoxypropyltrimethoxysilane (CAS NO.2530-83-8) can also be used to improve the cohesiveness
of caulking glue and sealant with water containing acrylic latex used in polyurethane and epoxy resin coatings.
It can improve the solubility, dispersity and fluidity of adhesive when put it into the organic toner.

Packaging and Storage:

3-Glycidoxypropyltrimethoxysilane is packed in 25KG/200KG drum, IBC tank or ISO tank.
It is sealed and stored in cool and well ventilated place away from fire and water.
