Novel isocyanate-free 1k moisture cure protective coatings based on vinyi neo esters and alkoxysilanes

摘要

Reactions between silanes and organic monomers offer an infinity of possibilities to optimize the performance of resins intended for coating applications.These copolymers are well-suited for high-durability protective applications.In particular,coatings based on acrylic-alkoxysilanes copolymers are currently used as isocyanate-free alternatives for a variety of highly demanding applications,such as marine coatings.Additionally,these systems can,in principle,be formulated as moisture-cure single-component(1K)coatings.However,acrylic-alkoxysilanes exhibit drawbacks,such as slow room-temperature cure and high raw material cost.Despite their high potential,acrylic-alkoxysilanes have had so far only fairly limited market penetration.
