Adhesion Promoter 丨 Filler Treatment Agent 丨 Surface Modifier

Product description:

Crosile® 5203 is a low-viscosity amino-functional silane polymer that forms a weather-resistant bonding interface on inorganic substrates (aluminum, glass, concrete) and various plastics. It also acts as a coupling agent for mineral fillers, imparting flexibility and hydrophobicity to the system

Technical Specifications

Amino Silane Polymer Application

Construction Adhesives & Sealants

- Compatible with MS, SPUR, PU, epoxy, RTV-silicone systems; can be blended directly or

used as a primer to simplify application. Transparent Decorative & Electronic Sealants

- Maintains optical clarity; suitable for bonding PC, PET plastic frames or lamp covers. Mineral-Filled Composites

- Pre-treatment of fillers such as aluminum hydroxide, calcium carbonate, or silica powder

improves dispersion and reduces brittleness. Industrial Marine & Protective Coatings

- Dilute and apply by roller or spray to concrete, glass, or aluminum surfaces to create a

hydrophobic, salt-fog-resistant layer.

Usage

- Additive: 0.5–2.0 phr, added directly during mixing. - Primer / Filler Treatment: Dilute to 5–20 wt% with alcohol or hydrocarbon, apply or mix

and dry before further processing
