Abstract
본 발명에 따른 고경도 내후성 하드코팅 조성물은 아크릴 폴리올 수지, 실란 화합물, 충전재 및 유기용제를 포함함에 따라 기재, 특히 금속기재와의 부착성이 뛰어나고, 우수한 표면의 경도, 내스크래치성을 확보할 수 있다. 여기에 금속기재의 녹슬음을 방지하고 오염 및 변형 방지 등의 고기능성을 발현함으로써 표면 보호를 위해 하드코팅층의 형성이 필요한 목재, 건축자재, 가구, 장식, 자동차내외장재, 패널 등에 폭넓게 사용 가능하다.The high-hardness, weather-resistant hard coating composition according to the present invention includes an acrylic polyol resin, a silane compound, a filler, and an organic solvent, so that it has excellent adhesion to substrates, especially metal substrates, and can secure excellent surface hardness and scratch resistance. there is. Here, it can be widely used in wood, building materials, furniture, decoration, automobile interior and exterior materials, and panels that require the formation of a hard coating layer for surface protection by expressing high functionality such as preventing rusting of metal substrates and preventing contamination and deformation.
Description
본 발명은 고경도 내후성 하드코팅 조성물에 관한 것으로, 상세하게는 금속 자재에 부여되는 코팅층을 통하여 표면의 경도를 높임과 동시에 내화학성, 내오염성, 내마모성, 내황변성 및 방청성 등의 고기능성을 부여할 수 있는 고경도 내후성 하드코팅 조성물에 관한 것이다.The present invention relates to a high-hardness, weather-resistant hard coating composition, and in detail, through a coating layer applied to a metal material, to increase the hardness of the surface and at the same time to impart high functionality such as chemical resistance, stain resistance, abrasion resistance, yellowing resistance and rust prevention. It relates to a high hardness weather resistant hard coating composition.
락카는 건축물, 가구, 전선 등의 물체 표면에 칠해져 고체막을 형성함으로써 물체의 표면에 방오, 방청, 방염, 방수성 등의 기능과 광택 및 컬러로 인한 심미성을 부여하기 위하여 사용되는 것으로, 일반적으로 용매에 수지를 희석하여 제조되며, 여기에 사용되는 수지와 용매의 종류는 매우 다양하다.Lacquer is applied to the surface of objects such as buildings, furniture, and wires to form a solid film, which is used to impart functions such as antifouling, rust prevention, flame resistance, and waterproofness to the surface of objects and aesthetics due to gloss and color.
