Andisil® 1189 silane
- Chemical Family
- Silanes
Andisil® 1189 Silane is a bifunctional silane possessing reactive secondary amine and hydrolysable methoxysilyl groups. The dual nature of its reactivity allows Andisil® 1189 Silane to bind chemically to both inorganic (glass, metals, fillers) and organic polymers (thermosets, thermoplastics and elastomers) functioning as an adhesion promoter or surface modifier and can be used for the chemical modification of substances. Andisil® 1189 Silane is a colorless to slight yellowish liquid with a light amine-like odor that is soluble in alcohols, and aliphatic or aromatic hydrocarbons.

- Application
Andisil 1189 Silane has many important applications:; As a size constituent or finish for glass fabric composites; As an additive and for the chemical modification of adhesives and sealants; For pretreatment of fillers and pigments used in mineral-filled polymers; As a primer and additive for improving the adhesion of paints and coatings to the substrate.; As a high flexible adhesion promoter in SMP-systems; The most important product properties that can be achieved using Andisil® 1189 Silane include:; Flexural strength, tensile strength and modulus of elasticity; Improved moisture and corrosion resistance; Andisil® 1189 Silane reacts rapidly with isocyanate groups and (being a secondary amine) eliminates the undesirable side reactions produced by primary amines. This allows a very clean reaction with isocyanate terminated pre-polymers to produce SPUR polymers resulting in trialkoxy terminated pre-polymers. The polymers cure rapidly upon exposure to moisture, but no longer contain free isocyanate groups which present a sensitization hazard. Also, isocyanate functional adhesives and sealants can generate bubbles upon reaction with excess water which are detrimental to product performance. These are very useful in adhesives, sealants and coatings. This allows the formulator to develop proprietary SPUR polymers that are not commercially available, so properties can be tailored to their specific needs
