Dynasylan® VPS 4721 is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows VPS 4721 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent and/or surface modifier. Dynasylan® VPS 4721 is a colorless liquid. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

Dynasylan® HYDROSIL 1151 is an amino-functional silane which acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers). Dynasylan® HYDROSIL 1151 is a colorless to slightly yellowish aqueous solution with an amine-like odur, miscible, with alcohols or water. Dynasylan® HYDROSIL 1151 contains about 40% active silane content in water.

Exolit® AP 740 S is a white free flowing powder. It is a non-halogenated additive flame retardant based on ammonium polyphosphate which develops its effectiveness through phosphorus/nitrogen synergism. Exolit® AP 740 S differs in its mode of action from chlorine or bromine containing flame retardants by achieving its effect through intumescence and has compared to Exolit® AP 740 a reduced water uptake. The flame retarded material foams on exposure to flame. The carbon foam layer so formed protects the polymer through its heat-insulating effect and reduces further oxygen access.
