Advanced Silane Solutions for Adhesion, Durability, and Surface Performance with Luna-sil
Delivering high-performance formulations in rubber, coatings, plastics, and adhesives requires versatile and reliable solutions. DKSH Performance Materials introduces Luna-sil, a comprehensive silane range designed to enhance adhesion, durability, and surface performance across multiple applications.
Why Choose the Luna-sil Range ?
Luna‑sil is a range of functional silane additives used to improve interfacial bonding, durability, and performance in rubber, coating, plastic, adhesive, and composite formulations. Luna‑sil products can be used either as formulation additives or as surface primers, depending on the application and substrate requirements.
Silanes in the Luna‑sil range act as molecular bridges between inorganic surfaces (such as fillers, glass, or metal oxides) and organic polymer matrices, helping to enhance compatibility and long‑term stability.
Why are silanes used in rubber, coating, and plastic formulations?
Many formulation challenges arise from poor interaction between fillers, substrates, and polymer systems. Without adequate interfacial bonding, formulations may suffer from:
-
Weak adhesion to substrates
-
Reduced mechanical strength
-
Poor durability under heat, moisture, or UV exposure
-
Inconsistent performance across different materials
Silanes are used to address these challenges by chemically linking dissimilar materials within a formulation or at an interface.
How does Luna‑sil function as an adhesion promoter?
Luna-sil silanes contain reactive functional groups that can bond with both inorganic surfaces and organic resins. This dual reactivity allows them to:
-
Improve adhesion between coatings and difficult substrates
-
Enhance bonding between fillers and polymer matrices
-
Increase resistance to moisture‑induced delamination
Because different Luna‑sil grades are compatible with a variety of resin chemistries, they can be adapted to multiple formulation requirements.
How does Luna‑sil influence polymerisation and durability?
When used in reactive systems, Luna-sil can participate in or support polymerisation processes, contributing to:
-
Improved cohesion within the polymer network
-
Enhanced mechanical properties
-
Increased resistance to environmental stress
These effects are particularly relevant in applications where long‑term durability and adhesion retention are critical.
How is Luna‑sil used for surface and filler treatment?
Luna-sil silanes can be applied as:
-
Surface treatment agents, improving substrate wetting and adhesion
-
Coupling agents for fillers in rubber and plastic systems
In filler‑loaded systems, Luna‑sil helps improve dispersion and stress transfer between the filler and polymer matrix, which can lead to better mechanical performance and process stability.
Why is Luna‑sil suitable for UV‑curable coatings?
In UV‑curable systems, adhesion and surface compatibility are essential for achieving consistent curing and coating performance. Luna‑sil is suitable for UV coating applications because it:
-
Supports adhesion to challenging substrates
-
Maintains performance under energy‑efficient curing conditions
-
Helps reduce adhesion‑related defects
This makes Luna‑sil applicable in formulations where fast curing and surface performance must be balanced.
What are typical formulation considerations when using Luna‑sil?
When formulating with Luna-sil, formulators should consider:
-
Compatibility with the selected resin system
-
Whether the silane is used as an additive or a primer
-
Interaction with fillers, pigments, and other additives
-
Processing conditions such as moisture, temperature, and curing method
Dosage levels depend on application type, substrate, and performance targets and should be optimised through formulation trials.
