The epoxy functionality of Silquest A-186 silane can react with a variety of organic functionalities, offering low yellowing adhesion in many resin systems. The trimethoxy silane functionality has a fast hydrolysis rate which can help accelerate the attainment of final properties.

With a combination of functionalities Silquest A-186 silane can help deliver numerous property enhancements to formulations, including:

• Bonding between resin and substrate or filler, and determent of water ingress and/or surface corrosion in electronic encapsulants and packaging materials, thereby supporting the stability of electrical properties and the reduced risk of electronic component failure
• Substrate adhesion in many water-borne acrylic and vinyl-acrylic caulks, adhesives and coatings.
• Adhesion to glass and metal substrates for epoxy, urethane and acrylic-based adhesives, sealants and caulks
• Adhesion with minimized yellowing in SPUR+ prepolymer applications
• Shelf stability and adhesion to glass and metal substrates in urethane applications
• Wet and dry adhesion, tensile strength and water resistance in quartz-filled epoxy encapsulants, sand-filled epoxy concrete repair materials, and metal-filled epoxy resins for mold die tools
