URE-FIL® 7

URE-FIL® 7

Smooth-On URE-FIL®填充剂可轻松分散在Smooth-On材料中。它们可以以不同比例添加到材料中,以实现各种工作特性和效果。一些填充剂是为了节约成本而设计,一些填充剂是为特定的浇注效果或改进物理性能而设计。一些UREFIL®填充剂专为增稠材料而设计,于刷涂或镘涂应用场合。
 
URE-FIL®7与聚氨酯树脂和可浇注环氧树脂充分混合,将改善尺寸稳定性(降低一些树脂的收缩率,例如)。它也经常添加到材料中,使其阻燃。URE-FIL®7可与Smooth-Cast®325和SO-Strong®颜色混合,形成大理石效果。不影响固化树脂的物理特性,可以添加到树脂中的最大量为1A:1B添加2份填充剂。1A:1B添加3份填充物的混合比将使树脂可镘涂,但固化后的树脂也会变脆。

特征

说明

URE-FIL® fillers must be thoroughly dispersed in liquid rubber or resin to a uniform consistency. When adding large concentrations of filler, it is recommended to add the filler to completely mixed rubber or resin - combine both parts A and B of rubber or resin, mix throughly, then add filler. Mix the filler in and confirm that there are no lumps of filler present. Often, employing the ‘double-mix and pour’ technique can produce better results.
 

Guarding Against Moisture - All powder fillers will absorb atmospheric moisture over time which will react with urethane materials. If you experience bubbling or foaming in your resin/filler mix, your filler probably contains moisture.

Remedy: Line a cookie sheet with foil and spread filler evenly over the cookie sheet at 3/8”-1/2” thickness (0.95 cm-1.25 cm). Place in an oven on warm setting (100°F / 38°C) and bake for two hours. Remove cookie sheet from oven (don’t burn yourself!) and redistribute filler on cookie sheet. Place back in oven and bake for two hours. Let filler cool to room temperature before mixing with urethane materials.

Storage - To prevent moisture absorption, use filler as quickly as possible after purchasing. Decant filler from container and replace lid immediately...do not leave container opened for more than a minute. If filler will be stored for prolonged periods, obtain dessicant pouches at your local hobby/arts and crafts store and place one or two dessicant pouches in container. Replace used dessicant pouches every other time you open container. Make sure container lid is secure before storing.
