Glycidyl Methacrylate Chemical Raw Materials GMA for polymer synthesis and modification

Description

Glycidyl methacrylate ( GMA ) is an ester of methacrylic acid and glycidol, it is a common monomer used in the creation of epoxy resins.

While typical home epoxies contain diglycidyl ether of bisphenol A ( DGEBA ), glycidyl methacrylate is instead used to provide epoxy functionalization to polyolefins and other acrylate resins.

For adhesives and non - woven fabrics, it can improve the adhesion of metal, glass, cement, polyfluoroethylene and other adhesives. The non - woven fabric used for the synthesis of latex can improve its resistance to washing without affecting the sense of touch. When used in the processing of synthetic resin materials, it can improve the injection molding, extrusion molding, and obviously improve the adhesion of resin and metal.

Used for synthetic fiber, it can improve its shading force and color fastness, improve the anti - wrinkle and anti-shrinkage ability. This product can improve the sensitivity, resolution and corrosion resistance of photoreceptors. This product and polyolefins grafting can improve tensile strength and bending strength.In addition, this product can be used as the raw material for ion exchange resin, chelating resin, selective filtration membrane for medical treatment, anticoagulant, dental materials, and dissolubility adsorbent. It is also used in rubber modification.

Application

Glycidyl methacrylate has a double bond and epoxy groups, so it can both have free radical reaction and ionic polymerization, which is widely used in medicine, photographic materials, organic synthesis, polymer synthesis and modification, and many other fields.

It is mainly used in the following areas:

A. Industrial protective topcoat, alkyd resin, which helps to improve the heat resistance and impact resistance;

B. Plastic modification;

C. Adhesives for thermosetting coatings, fiber treating agents, antistatic agents, vinyl chloride stabilizers, rubber and resin modifiers, ion exchange resins and printing inks;

D. Flame - retardant materials, absorbent materials;

E. Pressure - sensitive adhesive, anaerobic adhesive, non - woven plastic adhesive and other adhesives;

F. Acrylic and polyester decorative powder coating which is to improve the compatibility of thermoplastic resin;

G. The synthesis of acrylic emulsion or resin synthesis; PVC coating.

3- Mercaptopropylmethyldiethoxysilane Chemical Raw Materials for metal oxide-cured elastomers

Description

Chemical Name: 3- Mercaptopropylmethyldiethoxysilane
Specification:
Purity: ≥98%
Formula: C8H20O2SSi
Molecular Weight: 208.3937
Molecular Structure:
 

Applications

1. Silane coupling agent - 3- Mercaptopropylmethyldiethoxysilane is a mercapto-functional silane that finds use as a coupling agent in polysulfide and polyurethane caulks and sealants.

2. It is especially useful in sulfur-cured and metal oxide-cured elastomers. Chemically bonding reinforcing minerals like silica, clay, mica and talc to the polymer matrix, properties including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time are improved in mineral-filled elastomers.

3. It can be used as a pretreatment on minerals or added at the time of compounding. Being a rather efficient and fast sulfur containing silane, typically lower silane loading levels are used.

Packing & storage

200L PVF steel drum or on request.
Stored in a cool, dry place. Avoid light.
