UV三防漆是一種單組分UV紫外線光固化的改性丙烯酸酯密封涂料，三防膠水表面的涂層遇到紫外線，可達到瞬間表面固化，固化速度快是一般三防膠無法比的；主要用于PCB電路板、電子元器件、防水器件、電機電器產(chǎn)品、光電產(chǎn)品、玻璃、金屬及各種塑料的表面披覆后起保護作用。  具有粘度低、滲透性強、流平性好、固化速度快等特點；固化物韌性好，對大部分材料附著力優(yōu)良，具有良好的三防及耐溫，耐濕，耐老化功能。披覆過后的材料表面具有防潮、絕緣、防塵、防電暈等功能。

UV三防漆與其它種類的三防漆一樣，主要作用都是用于保護線路板。不同種類的三防漆，性能與特點也都有一定的區(qū)別。

產(chǎn)品特點：
 1. 粘接材料廣泛，對各種電路板基材、塑料、玻璃、金屬等材料都有極高的附著力；
 2. 表面固化速度快，高功率紫外線燈照射下可迅速達到表面脫粘效果；
 3. 柔韌性配方，可以對軟性電路板及軟性塑料進行披覆；
 4. 粘度低，具滲透性，可應用機械進行噴涂；
 5. 可防潮、耐高溫、高濕、抗紫外線，產(chǎn)品在惡劣環(huán)境下性能保持穩(wěn)定；
 6. 選擇熒光效果配方，  固化后用低功率紫外線燈在暗室照射膠層會呈藍色，具有可檢查性。

 7.環(huán)境影響固化后的UV三防漆雙固化披覆膠對機械沖擊、沉積物、潮濕、灰塵、腐蝕氣體等都有非常好的耐腐蝕效果。

UV three proofing paint is a kind of one component UV UV curing modified acrylate sealing coating. The coating on the surface of the three proofing glue can achieve instantaneous surface curing when it encounters ultraviolet light, and the curing speed is faster than that of ordinary three proofing adhesive. It is mainly used for the surface coating of PCB circuit board, electronic components, waterproof devices, electrical and electrical products, photoelectric products, glass, metal and various plastics After that, it plays a protective role. It has the characteristics of low viscosity, strong permeability, good leveling property and fast curing speed; the cured product has good toughness, excellent adhesion to most materials, good three proofing, temperature resistance, humidity resistance and aging resistance. The coated material surface has the functions of moisture-proof, insulation, dust-proof and corona proof.
