Silco
Silco Inc. is a leading manufacturer of high-performance sealants and adhesives, specializing in advanced silicone and hybrid technologies. They are committed to solving critical application problems such as poor adhesion, seal failure, color mismatch, and UV instability across commercial, industrial, and residential construction.
The Silco product line at Chemical Concepts features a full spectrum of sealant chemistries designed for diverse applications and substrates:
- Neutral Cure Silicones: These formulations are prized for being non-corrosive and low-odor, offering superior, primerless adhesion to a broad range of materials, including plastics and masonry. They maintain excellent permanent flexibility and high capacity for joint movement.
- Hybrid Sealants (Silyl-Terminated Polyether – STPE): Representing the next generation of performance, these sealants combine the strength and paintability of polyurethane with the extreme weathering and UV resistance of silicone. They are a high-performance, low-VOC, solvent-free choice for durable seals.
- Acetoxy Cure Silicones: This versatile category provides high elasticity and exceptional UV stability. Included are specialty formulas, such as those engineered for high-temperature applications.
