SUPER-HYDROREPELLENT COATING COMPOSITION, A SUPER-HYDROREPELLENT COATING LAYER WITH HIGH DURABILITY INCLUDING THE CURED PRODUCT OF THE COMPOSITION, AND A HEAT EXCHANGER INCLUDING THE SUPER-HYDROREPELLENT COATING LAYER

摘要

PURPOSE: A super-hydrorepellent coating composition is provided to the characteristics of the cured material of polyorganosiloxane having high bondability, thermal expansion, elasticity and temperature stability, low surface tension, and thermal shock durability and the characteristics of nano materials having high contact angle.;CONSTITUTION: A super-hydrorepellent coating composition(4) comprises, based on 100 parts by weight of polyorganosiloxane, about 0.1-500 parts by weight of nano materials(8), about 1-200 parts by weight of cross-linking agents, and about 0.001-10 parts by weight of catalysts. A method for preparing a super-hydrorepellent coating layer comprises a step of applying the super-hydrorepellent coating composition including nano materials to the surface of a base material(6) and curing the resultant.;COPYRIGHT KIPO 2012
