Product Manual:
Dynasylan ® 2201EQ is a bifunctional silane that includes urea groups and hydrolyzable ethoxy groups. It can be used as a bond between inorganic materials (such as glass, metals, and fillers) and organic polymers (including thermoplastics, thermosets, and elastomers). Promoters, surface modifiers and raw materials for the synthesis of other compounds. Dynasylan ® 2201EQ is a colorless liquid with a mellow taste, soluble in solvents such as alcohols, aliphatic and aromatic hydrocarbons.
Features and use:
In the presence of water, the ethoxy functional group of Dynasylan ® 2201EQ can be hydrolyzed to form the corresponding silanol, the reactive silanol can be bonded to the inorganic substrate, and the urea of the organic substance can be combined with a suitable polymer . Acidic conditions can catalyze the hydrolysis of Dynasylan ® 2201EQ. Dynasylan ® 2201EQ and suitable inorganic substrates are glass, fiberglass, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite and mica, aluminum hydroxide, kaolin, talc, other silicate fillers, metal oxidation Objects and metals. Organic substances include epoxy resin, polyurethane, phenolic resin, furan resin, melamine resin, polyethylene, polypropylene and silicone rubber.
Application:
Dynasylan ® 2201EQ is an important and even essential component in many applications, such as:
Glass fiber / glass fabric composite material
Primer for glass and metal
Mineral fiber, insulating material, abrasive material: used as an additive for phenolic resin binder
Resin for casting: used as an additive for phenolic, furan and melamine resins
Sealants and adhesives: used as primers or additives, and chemically modified
Mineral filled composites: pretreatment of fillers and pigments
Paints and coatings: used as additives and primers to increase the adhesion to the substrate
The important effects that can be obtained with Dynasylan ® 2201EQ are
Improve product performance
Improve bond strength
Improve mechanical properties, including bending strength, tensile strength, impact strength and elastic modulus
Moisture resistance and corrosion resistance
Electrical properties, such as dielectric constant, volume resistance
Improve processing performance
Better dispersion of filler
Rheological behavior: reduce viscosity, Newtonian behavior
Higher filling level
Craftsmanship
When used for substrate pretreatment, for example, as a primer (approximately 1-10% solution), Dynasylan ® 2201EQ can be conveniently used in various forms, can be added in organic solvents such as alcohol, or in solution, or Add to the polymer in pure Dynasylan ® 2201EQ mode or as an additive.
