光滑的泡沫!该系列由两组分硬质泡沫组成,用途广泛,使用方便。泡沫吧!每立方英尺的密度为3磅、5磅、8磅、10磅、15磅或26磅。A和B部分的测量和混合按体积相等(注:泡沫)!8按重量测量并混合2a:1b)。然后将混合物倒入模具或其他形式(如有必要,可涂上隔离剂)。混合物会膨胀很多倍的原始体积(取决于哪个泡沫)!并开发出一个统一的细胞结构。泡泡吧!3、5、10、15和26在大约4-6.5分钟内无粘性,在20分钟内提高处理强度,在2小时内完全固化。泡沫吧!10慢是10磅密度泡沫,工作时间较长,3.5分钟,1小时达到处理强度,4小时固化。泡沫吧!10 Slow设计用于大型浇注应用,可用于各种工业、艺术相关和特殊效果应用。泡沫吧!8是一种独特的自表皮泡沫,具有比其他泡沫更细、更均匀的细胞结构!产品。泡沫吧!26是一种高密度刚性泡沫,它非常坚硬和非常坚固。泡沫吧!8、15或26可以作为一个可加工的原型建模板铸成块。全泡泡啦!产品可作为直浇材料、空心铸件的回填料(增加结构强度)或作为封装材料等。它们可以用如此强烈的颜色着色,用于各种艺术/工艺、工业设计和特殊效果应用。 Smooth-On's FOAM-iT!® Series are two-component water blown rigid foams that are versatile and easy to use. FOAM-iT!® products are available in 3lb., 4 lb., 5 lb., 8 lb., 10 lb.,15 lb. or 26 lb. per cubic foot densities. Parts A and B are measured and mixed in equal amounts by volume (Note: FOAM-iT!® 8 is measured and mixed 2A:1B by weight). The mixture is then poured into a mold or other form (apply release agent if necessary). The mixture will expand many times original volume (depending on which FOAM-iT!® product you are using) and develop a uniform cell structure. FOAM-iT!® 3, 4, 5, 10, 15 and 26 have a handling time of about 20 minutes and reach full cure in 2 hours. FOAM-iT!® 4 Black is pre-pigmented to a very deep black color. FOAM-iT!® 10 SLOW is a 10 lb. density foam with a long, 3.5 minute working time, taking 1 hour to reach handling strength and 4 hours to cure. FOAM-iT!® 10 SLOW is designed for large-pour industrial, art-related and special effects applications. FOAM-iT!® 8 is a unique, self-skinning foam with a finer, more uniform cell structure than the other FOAM-iT!® products. FOAM-iT!® 8, 15 or 26 can be cast in blocks as a machinable prototype modeling board. All FOAM-iT!® products can be used as a straight casting material, backfill material for hollow castings (adds structural strength) or as an encapsulation material, etc. They can be color pigmented with SO-Strong®, UVO® or IGNITE® colorants and are used for a variety of art/craft, industrial design and special effects applications. |
