SO-FLEX®

SO-FLEX®

SO-FLEX®为软化剂,可降低各种Smooth-On软质聚氨酯产品的固化后硬度。下表显示SO- FLEX®按混合总量百分比添加,在完全固化(7天)时对PMC®-121/50和PMC®-744的效果。SO-FLEX®也可以添加到Vytaflex®10中制作聚氨酯“凝胶”型材料。

说明

Safety – Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Store and use products in a warm environment (73°F / 23°C). This product has a limited shelf life and should be used as soon as possible. Wear gloves and eye protection to minimize risk of contamination.

MEASURING & MIXING...

Use SO-FLEX® by weight: For best results, you should use an accurate scale to properly use SO-FLEX® with PMC®-121/50, PMC®-744, Vytaflex® or any other flexible Smooth-On polyurethane product. SO-FLEX® should be weighed and thoroughly mixed (at least one minute) with the appropriate amount of Part B before combining with Part A.


Softening PMC®-121/50 with SO-FLEX® - Normally, PMC®-121/50 cures to a hardness of Shore A 50. PMC®-121/50 can be made softer and more flexible by adding different percentages of SO-FLEX® as indicated below.

Part B SO-FLEX® Mix Thoroughly Part A Hardness
50 g 0 g Mix 50 g Shore 50A
50 g 20 g Mix 50 g Shore 43A
50 g 40 g Mix 50 g Shore 35A
50 g 50 g Mix 50 g Shore 30A

Using SO-FLEX® by volume with PMC®-121/50: If you want to add SO-FLEX® by volume instead of by weight, you can do so by measuring out equal amounts of parts A, B or SO-FLEX®. As indicated above, this will result in a cured Shore A hardness of 30.


Softening PMC®-744 with SO-FLEX® - Normally, PMC®-744 cures to a hardness of Shore A 45. PMC®-744 can be made softer and more flexible by adding different percentages of SO-FLEX® as indicated below.

 

Part B SO-FLEX® Mix Thoroughly Part A Hardness
50 g 0 g Mix 100 g Shore 45A
50 g 20 g Mix 100 g Shore 40A
50 g 40 g Mix 100 g Shore 35A
50 g 50 g Mix 100 g Shore 30A

 


Softening Vytaflex® 10 with SO-FLEX® - Normally, Vytaflex® 10 cures to a hardness of Shore A 10. Vytaflex® 10 can be made into a much softer and more flexible ‘gel’ type material by adding different percentages of SO-FLEX® as indicated below.

 

Part B SO-FLEX® Mix Thoroughly Part A Hardness
50 g 0 g Mix 50 g Shore 10A
50 g 10 g Mix 50 g Shore 00-62
50 g 20 g Mix 50 g Shore 00-50
50 g 50 g Mix 50 g Shore 00-30

Note: The softened Vytaflex® 10 will be ‘tacky’ when cured. This tackiness can be eliminated by applying baby powder or talc to the surface of the cured rubber.
