General Use
How would you explain the difference between regular Lab-metal and Lab-metal 450?
Regular Lab-metal air dries and can be sanded smooth.
Lab-metal 450 air dries but then needs to be heat cured prior to sanding and should only be used if for powder coating temps up to 450F.
How do I determine the shelf life of Lab metal/ Hi Temp Lab metal
Lab metal shelf life = 2 years in an unopened can
Hi Temp Lab metal shelf life = 1 year in an unopened can
Batch sticker on top of can = expiration date
Distributors are advised to rotate stock, Lab metal and Hi Temp Lab metal should not contain any lumps (should be like creamy peanut butter) Contact Alvin Products for replacement.
After filling and air dried, can the hi-temp be sanded smooth before baking?
Repair needs to be baked first then sanded.
Can Lab-metal be powder coated?
Yes. Lab-metal will accept ground during coating. Powder coating of cast metal parts is a rapidly growing process due to environmental problems with solvent based coatings. The powder coating process normally requires the exposure of the metal part to temperatures in the range of 400ºF to 425ºF. Although these temperatures exceed Lab-metal's maximum recommended exposure temperature of 350ºF, because the time in the oven is normally less than 20 minutes, regular Lab-metal is being used very successfully in this process. Hi-Temp Lab-metal has also been proven in the powder coating process.
