无影胶无影胶（uv胶）又称光敏胶、紫外光固化胶，无影胶是一种必须通过紫外线光照射才能固化的一类胶粘剂，它可以作为粘接剂使用，也可作为油漆、涂料、油墨等的胶料使用。
UV是英文Ultraviolet Rays的缩写，即紫外光线。
紫外线(UV)是肉眼看不见的，是可见光以外的一段电磁辐射，波长在10~400nm的范围。
无影胶固化原理是UV 固化材料中的光引发剂（或光敏剂）在紫外线的照射下吸收紫外光后产生活性自由基或阳离子，引发单体聚合、交联化学反应，使粘合剂在数秒钟内由液态转化为固态。

单体有：单官能（IBOA、IBOMA、HEMA等）、二官能（TPGDA、HDDA、DEGDA、NPGDA等）、三官能及多官能（TMPTA、PETA等）引发剂有：1173，184，907，二苯甲酮等助剂可加可不加,它可以作为粘接剂使用，也可作为油漆、涂料、油墨等的胶料使用。
无影胶常见应用塑料与塑料、塑料与玻璃、塑料与金属等材料的粘接。
主要针对工艺品行业塑料的自粘和互粘，家具行业，例如茶几玻璃与钢架粘接，玻璃鱼缸粘接，包括PMMA亚克力（有机玻璃）、PC、ABS、PVC、PS等热塑性塑料。
无影胶产品特点通用型产品适用范围极广、塑料与各种材料的粘接都有极好的粘接效果；粘接强度高、通过破坏试验的测试可达到塑料本体破裂而不脱胶，UV胶可几秒钟定位、一分钟达到最高强度、极大地提高了工作效率；固化后完全透明、产品长期不变黄、不白化；对比传统的瞬干胶粘接、具有耐环测、不白化、柔韧性好等优点；P+R 按键（油墨或电镀按键）破坏实验可使硅橡胶皮撕裂；耐低温、高温高湿性能极优；可通过自动机械点胶或网印施胶、方便操作。

Refer to SDS for further information.StORAGESensitized Alpha E-50 emulsion has a shelf life of 4 to 6 weeks at room temperature (60 to 80°F). To maximize sensitized shelf life use only distilled water to dissolve diazo sensitizer.Protect from freezing. Alpha E-50 is not freeze/thaw stable. Freezing during shipping may result in clear gel spots which may resemble pinholes or emulsion may appear lumpy.Coated, unexposed screens can be stored as long as one month in a clean, cool, dry and completely dark area.Expiration date. Always check the expiration date on sensitizer bottle to assure freshness.Work under yellow lights.INStRUCtIONSDEGREASEUsing Degreaser 260 mesh degreaser, work up a lather on both sides of mesh. Flood screen and frame thoroughly with water, then dry.MIXMix emulsion and sensitizer according to instructions on bottle. Let emulsion stand at least two hours before using. Always stir emulsion before use. Contents may settle over long periods oftime. Gentle stirring will ensure that the emulsion is properly mixed. COAtFill scoop coater with room temperature emulsion. Slowly apply first coat to print side. Then coat squeegee side with one to three coats depending upon thickness required. If thicker stencil is required, additional coats may be applied to print side after initial drying of stencil. Be sure to dry thoroughly between coats. DRyThoroughly dry screen in horizontal position, print side down, using a dark, clean drying cabinet. Temperature should not exceed 110°F (43°C).EXPOSEPlace emulsion side of photopositive in contact with print side of screen.DEVELOPGently spray both sides of screen with tepid water, wait 30 sec-onds then gently wash print side of the screen until image is fully open. Rinse both sides thoroughly. Dry screen completely and you are ready to print.RECLAIMApply Chroma/Strip™ screen reclaimer to both sides of screen. Scrub area to be reclaimed with a stiff nylon brush to ensure entire surface is wet and let it work a few moments until stencil begins to dissolve. Remove stencil residue with pressure washer, then rinse with water, thoroughly flooding screen and frame. EXPOSURE GUIDELINESRefer to the Chromaline Exposure Calculator to determine optimal exposure times. Individual exposure times may vary depending upon equipment used, bulb age, and other shop conditions. AVOID fAILURE: Dual cure emulsions have a very wide expo-sure latitude. Underexposed stencils often appear acceptable, but premature breakdown can occur on the press. When determining exposure speed, always overexpose your test stencil. Then, using the Chromaline exposure calculator, reduce exposure time until acceptable image quality is achieved. This will help assure good durability.130208fOR tECHNICAL SERVICE Call Toll Free: 1-800-328-4261Email: *******************(Outside North America Call +1-218-628-2217)。

感光胶配方(多类型感光胶配方感光胶一般可分为耐溶剂型和耐水型两种。
耐溶剂型感光胶,可耐各种有机溶剂,适用于油性油墨的印刷;耐水型感光胶,适用于水性油墨(水溶性印刷涂料,如纺织品印花色浆的印刷,前者网版可以脱膜回收;后者一般不能脱膜回收。
专用耐水性感光胶有尼龙感光胶和重氮感光胶等。
用户必须根据承印对象,参照有关说明书选择使用适当的感光胶。
感光胶是用于直接法制版的丝印制版感光材料,还可分为单液型和双液型。
单液型感光胶在生产时已将感光剂加入乳胶中,使用时不需配制即可涂布;双液型感光胶在使用前要先将感光剂按配方说明溶释,然后再分散混合于乳胶中,消泡后方可涂布。
感光胶的型号、品种繁多,生产厂家的配方也不尽一致,选用时可根据承印物要求,参照产品说明书适当选择。
1.重铬酸盐感光胶。
此类感光胶的感光剂为重铬酸铵,成膜剂为水溶性高分子物质,如明胶、PVA及PVAC+PVA等。
此类感光胶可以自行配制,典型配方如下:①明胶感光胶配方明胶16g柠檬酸0.5g重铬酸铵 4.5g氨水3ml水70ml此胶的材料来源方便、价廉、水显影容易。
但胶液易冻、涂布不强、湿强度差、清晰性差,且日久会脆裂。
因此逐步被合成高分子材料所替代。
②PVA感光胶配方甲液:PVA(1788 50g十二烷基磺酸钠 0.5g水400ml乙液:重铬酸铵6g水50ml配方中十二烷基磺酸钠为分散剂。
PVA的聚合度为1200~1700,皂化度为88%,能兼顾到版膜强度和显影性能。
此胶较明胶的制版操作方便,版膜质量也有所提高。
缺点是分辨力低,耐水性差,受湿度影响大。
③PVA+PVAC感光胶配方甲液: PVA(1788 40g十二烷基磺酸钠0.5g冰醋酸 4.0ml水250ml乙液:重铬酸铵5g水30mlPVAC乳液 40ml曙红少量配方中冰醋酸可加速PVA溶解,改善显影;PVAC乳液的加入能提高版膜的粘网力和耐水性。
此胶的特点是各种耐抗性均有一定的提高。
重铬酸盐型感光胶是使用时间较长并得到广泛利用的一种丝网印刷感光胶,这种感光胶具有以下特点;光谱的光敏度在370~530mm之间;感光胶膜层可按比例进行光敏化;可选用任何一种光源进行晒版;曝光时间比较短;价格比较便宜。
光胶的原理
光胶，是一种用来固定物体或在表面上形成图形的物质。
通常是将树脂或光敏物质涂在玻璃上，然后经加热使其固化，可做成各种形状。
光固化胶通常是以紫外线为光源的，根据不同的要求，可选用不同波长的紫外线。
当紫外光照射在材料上时，紫外线被吸收了，而其它波长的紫外线则会被材料中的自由基所吸收。
此时，自由基数量增多，当达到一定数量时，就会产生“光化学”反应，产生新的自由基。
这些新的自由基又会与其他物质发生反应，形成新的物质。
如此循环往复，便形成了固化物质。
光胶在生产和生活中应用广泛。
例如：在电子工业中用作电路填充、芯片表面粘接、精密仪器制作、金属装饰、玻璃雕刻、雕刻宝石等；在建筑工业中用作模型粘结；在国防工业中用作激光固封；在医疗器械行业中用作外科缝合线等；在化学领域中用作各种反应和化学反应的催化剂。
光胶由光引发剂和光促进剂两部分组成。
光引发剂是使光胶固化的物质，它是由含不同基团的化合物组成的大分子。
