Product Application

Plastic Modification:

PE/PP Crosslinking: Used with peroxide initiators to crosslink via the vinyl group, improving heat distortion temperature, environmental stress crack resistance, mechanical strength, and heat resistance.

TPE Reinforcement: Improves the interfacial bonding between TPEs and fillers (e.g., silica, calcium carbonate, talc), enhancing mechanical properties, wear resistance, and tear strength of composites.

Rubber Industry:

Silica Reinforcement: A key additive for manufacturing "Green Tires." Reacts with silanol groups on silica surfaces, reducing filler agglomeration, lowering mixing viscosity, and improving tensile strength, abrasion resistance, and wet skid resistance of vulcanizates.

Filled Rubbers: Enhances dispersion and interfacial bonding of fillers like carbon black, clay, and mica in rubber matrices, boosting reinforcement effects.

Coatings & Inks:

Adhesion Promoter: Added to resins (e.g., acrylic, polyurethane, epoxy) to chemically bond with substrates (metals, glass, ceramics, concrete) via hydrolyzed silanol groups, significantly improving coating adhesion.

Surface Modifier: Improves pigment/filler dispersion and enhances coating leveling, gloss, and weather resistance.

Adhesives & Sealants:

Increases bonding strength to difficult-to-bond substrates (e.g., polyolefins, engineering plastics, metals, glass) for silicone, polyurethane, and epoxy adhesives/sealants.

Surface Treatment Agent:

Directly used for treating metal, glass, ceramic, and fiber surfaces to form an ultra-thin, inert organosilicon layer, altering surface energy to improve wettability, stain resistance, lubricity, or serve as a primer for subsequent coatings.

Resin Synthesis:

Used as a comonomer in synthesizing functional silicone resins and silicone-modified acrylics, polyurethanes, etc., imparting new properties (flexibility, temperature resistance, biocompatibility).

Composites:

Improves interfacial bonding between reinforcements (glass fibers, carbon fibers, mineral fillers) and resin matrices, serving as a vital additive for high-performance Fiber-Reinforced Plastics (FRP) and prepregs.

Storage

Store in a cool, dry, well-ventilated dedicated warehouse away from sparks and heat. Storage temperature should not exceed 30°C. Keep containers tightly closed. Separate from oxidizers, acids, and bases. Do not store together. Use explosion-proof lighting and ventilation facilities. Prohibit spark-producing machinery/tools.
