Product Description

Product Information

Product CodeLT-5701

Chemical Name:γ- (methacrylate) propylmethoxy isopropylsilane



LT-5701 is a reactive chemical with methacrylate organic functional groups and hydrolyzable inorganic functional groups. This bifocal structure gives LT-5701 special properties: it is able to bond inorganic materials (such as glass, silica) and organic thermosetting resins together to promote adhesion, crosslinking agents and/or surface modifiers.


It is a colorless transparent liquid sensitive to light and heat, with a distinct sweet odor, soluble alcohols, aliphatic or aromatic hydrocarbons.


Technical Data


Note: the above data are for reference only, can not be used as a technical specification



In the presence of water (and a suitable catalyst such as acetic acid), LT-5701's alkoxy groups will hydrolyze to form alcohols and active silanol groups, forming bonds on various inorganic substrates. Methacryloxy can react with suitable polymers.


Suitable inorganic materials such as: glass, glass fiber, glass wool, mineral wool, silica, quartz, sand, quartzite and mica; As well as aluminum hydroxide, kaolin, talc and other silicate fillers, metals and metal oxides.


Suitable resins for treatment include unsaturated polyester, acrylic and vinyl resins.



LT-5701 is used as a bonding accelerator in many applications, such as:

 Components of glass fiber infiltrators (glass fiber fillers for filling unsaturated polyester resins and polyolefin).

 Finishing agent for glass fibers filled with unsaturated resins.

 Surface modifiers for pigments and fillers of thermosolids (unsaturated polyester resins, MMA), thermoplastics (polyester and polyolefin) and elastomers.

 Used as an additive to peroxide-initiated crosslinked filled elastomers.

 Used as an additive to casting resins (unsaturated polyester, MMA).


LT-5701 can pretreat inorganic substrates by dipping, spraying or coating. It can also be added directly to the resin system (adding process). As a pretreatment, silane can:

 add directly.

 pre-dissolved in organic solvent.

 dissolves in a mixture of organic solvents and water to achieve partial hydrolysis.

 When fully hydrolyzed in an aqueous solution to prepare an aqueous pretreatment solution, LT-5701 should be dissolved in water in 1-5wt.- % and PH adjusted to 3-4 with acetic acid. When the silane is completely hydrolyzed, if the solution becomes cloudy again, it can no longer be used. In the addition process, LT-5701 can be mixed with resin or polymer beforehand or added simultaneously with filler. The prerequisite for this method is the compatibility between silane and the corresponding resin, so that silane must not react with the resin in advance.


The correct use of LT-5701 can achieve the following effects in unsaturated polyester resin systems with high filler loads:

 Improve dispersion of pigments/fillers

 Reduces pigment/filler deposition

 Reduces viscosity and improves resin fluidity

 Improve the mechanical properties of mold products

 Improve the mold product resistance to boiling water, acid and alkali


LT-5701 can also be used as a monomer in synthetic resins (e.g., emulsion dispersion polymerization) to partially replace the monomer oxidized by methylacrylyl (generally 0.5-3%, but sometimes up to 20%).

The introduction of silane into resin products can lead to a number of performance improvements in the final application:

 wet bond strength

◆ resistance to chemical attack

◆ Scratches resistance
